MCA-3M and L Medium Battle Tanks

Basic Design:

As probably one of the most recognizable and iconic machines within Sumer, among both military and civilian populations, the MCA-3 series of medium tanks continues to have a long lasting effect on a wide variety of subjects from military thinking to even popular culture. Since it's introduction in 10,340 the MCA-3 series has dominated the Sumerian Armed Forces and shaped modern tactical thought in almost every way. With over eighteen million, and counting, units produced to date the MCA-3 is potentially one of the most produced tanks in the world, and is certainly the most numerous tank in the Sumerian inventory. With more then four million MCA-3 series vehicles still in active, reserve, or storage status within the Sumerian Armed Forces, and over a million more in the hands of private citizen owners the MCA-3 has taken a place in history unique to itself, and unlikely to be rivaled in the foreseeable future.

The MCA-3 series, over it's half-century of service has participated in ever war fought by Sumerian forces, and operated in every environment possible for such a vehicle to operate. It has proven time and time again it's worth despite it's simple and lightweight construction and thinner protection then more modern medium tanks. It remains the stockpile tank of choice in Sumer due to it's highly modular nature and easy production. More then fifty years, and countless upgrades and design changes, after the first model rolled off the production lines for the Erimkalam it is still being produced. Production to replace aging storage and reserve stocks, as well as to bring fresh systems into the professional forces.

The MCA-3 is an old design, following the typical layout of most medium tanks with the engine in the rear and the fighting compartment in the middle, slightly forward, with the driver at the front. The MCA-3 was among the first Sumerian tanks to be fitted with composite armour, and was early on retrofitted with modular systems. It's design was highly influential in all MCA project designs following, including the newest MCA-7 series. The design as remained similar to it's roots for it's entire, and ongoing, production run, with advances in electronics, armour and armament all being incorporated into the basic design through it's life.

Although originally intended to fill the primary armoured combatant role, the MCA has over it's life increasingly been shifted to a more secondary role. Although still fully capable of competing with the latest tanks on the battlefield thanks to armour redesigns, weapons upgrades, and electronics upgrades, the MCA-3 is an old design and is becoming too light to sustain armoured formation combat that is necessary on the battlefield. In this respect it has been phased out of use in favor of the newer MCA-7 series of vehicles. This has not removed the MCA-3 from service however, as Mechanized Infantry formations have found themselves lacking in adequate high mobility armoured support, and terrain issues do not allow the MCA-7 to be employed everywhere. To this respect the MCA-3 has remained an active participant in the modern Sumerian armed forces, at the forefront of armoured warfare along with it's descendant the MCA-7. As well, despite two attempts to design a replacement for the MCA-3, it still remains popular with the troops, and is the dominant reserve tank in storage and reserve use. It's modular nature allows for continual production of partially complete vehicles to be put directly into surplus storage, allowing quick activation if needed.

Production of the MCA-3M will come into being shortly in twelve tank plants across south western Sumer, with an intended steady output of 40,000 new production units per year. Additionally the MCA-3L will be produced in four tank plants for a total of approximately 14,000 new units per year. Additionally upgrade kits will be made available and applied to reserve storage J models prior to their transfer to surplus storage.

History:

The MCA-3 was proposed shortly after the MCA-2 entered production as a replacement medium tank for future needs. A decade long design program culminated in prototype testing in 10,337. Within three years the first production vehicles, the MCA-3A, were rolling off the assembly lines to be delivered to Igimekalam units. In the fifty two years since the MCA-3 has undergone many major overhauls and upgrades, all of which it would be impossible to cover in detail.

The MCA-3A through J models were all designed for mutual Erimkalam and Igimekalam use, and are successive upgrades over the service life of the vehicle. The MCA-3K is a special vehicle for special forces use and is still in use today as a top secret system. The MCA-3N was variant designed for the Chamagudkalam and has since been retired in favor of the foreign made Nakil. Currently only J and K models are in service, with many H and I models upgraded to J standards in storage and previous models either scrapped, used as targets, or sold to civilian buyers. As the M and L models come into mutual service, with the only difference between the two being armour and weight, the H and I models are expected to be retired and sold or scrapped or used as targets while the J models are either replaced and sold, or upgraded to L standard and placed in surplus.

Armour:

The latest generation of the MCA-3, the M and L models, are designed with the most modern armour avalible. The general layout consists of three layers of applied armour. The basis for the vehicle is the primary componant armour itself which consists of the load bearing basic chassis which is constructed from a honeycomb titanium material cored with a fiberous synthetic rubber compound between the two honeycomb sections. This strong but lightweight design replaced the solid metal and spaced metal systems of previous chassis designs to add protection and reduce weight. Although older MCA-3 models can be upgraded to near M or L standards with their original chassis.

The second layer of the armour comes in the form of a titanium encased ceramic-metalic material with a depleted uranium mesh. This layer is broken into small modular blocks formed to fit specific parts of the tank and are installed along the hull front and glacias, as well as the hull sides, turret mantlet, front and sides, and on the M model the skirts and parts of the turret roof. These modular armour blocks are derived from the componants designed for the MCA-7 series, but are thinner and lighter and do not offer as much protection, and are additionally only installed on key areas of the vehicle.

Traditionally the third, and outermost, layer of the MCA-3's armour has been a flexible titanium cored synthetic rubber pannel which provides excellent protection and anti-magnetic mine protection. This has been updated with the addition of Shukur explosive reactive elements to the rubberized plates. The Shukur system allows greater protection for lighter weight at the cost of the cheap and disposable rubberized pannels.

Armament:

Both the M and L models of the MCA-3 are equipped with the new Type-3660 115L55 smoothbore tank gun, which is a shorter variant derived from the Type-3655 115L62 smoothbore gun of the MCA-7G. This weapon allows complete ammunition compatibility between the two vehicles, and enables the MCA-3 to gain incredible hitting power without the modifications that would have been required to the design to facilitate the much longer Type-3655.

The main gun is fed by a bustle mounted autoloader housing twenty-two rounds, with an additional twenty-two rounds stored in the hull to the right of the driver. This system is less efficient then the more advanced autoloader of the MCA-7 series, but is cheaper and easier to produce, and can be built by upgrading older autoloader from previous MCA series vehicles.

Also included is a 7.5mm coaxial machine gun, as well as mountings for machine guns up to 15mm in caliber for the commander, as well as the aerosol dispersion system and Enlil APS Type-1 defensive suit of the newest MCA-7 series tanks. This provides the MCA-3 with exceptional protection against all threats despite it's light weight and older design.

Mobility:

The MCA-3M and L variants are powered by the latest Guarita DO86-2S03 engine. The DO86-2S03 is described as the little brother to the DO86-2S99 engine powering the MCA-7 series, and provides a power output of 1200 brake horsepower. The engine itself is a twin supercharged six-cycle, eight cylinder, opposed piston engine and is essentially a scaled down DO86-2S99, with half the displacement. This provides the much lighter MCA-3 with a high power to weight ratio, allowing exceptional mobility on and off the battlefield.

Power is provided to the ground through the same Type-31A enclosed hydraulic transmission as the MCA-7G, and is as well designed to be installed as part of the engine package as a whole. Additionally a small gas turbine under armour APU is installed to allow power usage without running the main engine. The APU is also fully capable of "hot starting" the main engine as it is in the MCA-7.

The vehicle is fitted with seven road wheels per side, as well as four return rollers. The extra wide tracks of the MCA-7 have been retrofitted to the MCA-3 to allow it maximum mobility on the softest grounds as well.

Crew Systems:

The entire electronics and systems suit of the MCA-3 was redesigned for the M and L model, requiring extensive work to be done to rebuild older chassis to current specifications. The fire control system and computer from the latest MCA-7G models were incorporated into the MCA-3M and L, alongside the latest communications and electronics gear. Fully digital electronics, thermal viewing capable optics for the gunner and independent thermal and daylight viewing systems for the commander, as well as full satellite and radio capable communications gear which can integrate flawlessly with the standard Sumerian networks.

All new extra comfortable crew seating arrangements have been designed with built in tubed liquid cooling, as well as fool air conditioning of the vehicle and an NBC overpressure system. Water is carried for the new Guarita engine, as well as for crew consumption, and plenty of room is available for movement within the vehicle to allow crews long periods of operation. The digital and touch screen controls provided in the MCA-7 is also included in the MCA-3M and L versions in equal capacity.

Export Policy:

Recent export permission has been given to Nineveh Armoured Works to supply an export version of the latest MCA-7 series tank, the G, to foreign interests. The MCA-7E, as it is known, is a fully capable MCA-7G, unlike the previous B-to-C modifications for export. No reductions in protection or capability were made to achieve the E, and only a limited number of modifications were made to the vehicle for export. The following writeup is for the MCA-7G, however the E model is completely identical in all aspects except for the following:

- The MCA-7E package does not include the An-1100H round for export.
- The MCA-7E computer systems have all been built with blank software around the standard systems. This means that the FCS or other systems can be configured to foreign languages and needs, while retaining all capabilities except one.
- The MCA-7E is unable to synchronize with the Sumerian Battle Network because of the previously mentioned computer construction, and safeguards in place. It can easily, however, be configured to work with local BattleNets.

The following ammunition is avalible for export under the conditions specified:
- An-1100A: Production rights come with vehicle purchase.
- An-1100B: Production rights come with vehicle purchase.
- An-1100C: Production rights come with vehicle purchase.
- An-1100D: Production rights come with vehicle purchase.
- An-1100E: Production rights come with vehicle purchase.
- An-1100F: Production rights come with vehicle purchase.
- An-1100G: Avalible for $32,000 USD per missile. ($1.6 billion DPR)
- An-1100H: Not Avalible for Export.

Spare parts production rights are avalible. It should be noted that all technology and equipment design integrated within the MCA-7E is property of the Sumerian government and is thusly copywritten. Any attempt to produce, in whole or in part, the MCA-7E or any of it's componants for export will be reciprocated with actions as deemed fit, up to and including military action.
Further, we wish to issue the following disclaimer: Nineveh Armoured Works, nor the Sumerian government or any of the subcontractors involved in the MCA-7 program can be held responsible for the quality of work by foreign producers under domestic production rights. While we strive to aid foreign industry to the quality demanded by the MCA-7, we hold no responsability in their construction.

We thank you for reviewing the MCA-7E, and hope to do buisness with you in the future. Please review the export costs in the statistics section at the end of the article. Avalible is single unit export, limited production export, where you buy the right to build the vehicle in a specific limit based on a lower cost, and full domestic production rights. Full DPRs are more epensive then limited, and are restricted on a case by case basis. We would also like you to review the PIV-28 Heavy Infantry Combat Vehicle, which is also avalible.

Concept:

The MCA-7G model came into existance after practical application of the MCA-7B in combat both on the northern border and aborad. Lessons learned from the B, as well as other tanks in the Sumerian inventory, quickly culmulated with new technological advancements avalible for general use. The MCA-7G was thusly born out of the idea that although the MCA-7B was highly capable and exceptional in it's abilities, it was not at the full potential of the design, and so the G model upgrade project was begun.

Shortly after the release of the MCA-7B to general use within the Igimekalam number of vehicles were set aside specificly for testing new and potential future upgrades. Nineveh Armour Works, the primary contractor for the MCA-7 series, began to redesign aspects of the main armament and drive train for test purposes. Testing proved the design path to be quite strong, with many of the new test systems proving, to a degree, superior to those installed already on the B model.

And so, with combat experiance providing the nessesary information, a program to update the MCA-7Bs was put forth before the Office of the Dictator. After several months of rehashing the program's goals with the Office, the final program was approved for development and brought before the Civil Senate for funding. Several weeks later, and the rewriting of the program to include the approval of systems slated for the MCA-7B upgrade to be used in the MCA-7D and other armoured vehicles, the project was approved for funding and allocated the nessecary funds. The update program, designated as the MCA-7G, was concieved around primarily updating the internal systems of the MCA-7, with a new fire control, battlefield managment system, sensors, and other systems. Additionally the entire drivetrain was redesigned to better suit the vehicles needs and capabilities, as well as new armament and an upgrade to the protection scheme.

Although externally identical to the MCA-7B, the G model holds a signifigant number of improvements that make it a clearly superior vehicle. With primary emphisis on a vehicle to combat other armoured formations in the vast open plains of Sumer, the G model contains a carefully calculated balance of firepower, mobility, and protection, with no detriment to its primary mission.

Armament:

The MCA-7G uses a brand new gun derived from the Type-3655 115L62 smoothbore of the prototypes. The new gun, the Type-3700 140L50 is a 140mm weapon scaled up from the older Type-3655 design. The new gun allows higher muzzle velocities, as well as larger projectiles and gun launched anti-tank guided missiles. The Type 998-X16B autoloader system has been also upgraded to Type 998-X16C standards to keep up with the main gun.

The new Type-3700 smoothbore main gun installed in the G model is a larger version of the Type-3650 installed in the B model and Type-3655 installed on the G model prototypes, as previously stated. The new gun is designed to maximize space within the combustion chamber for propellant while allowing a slightly longer barrel for greater expansion of the higher power rounds. The mantle and gun mount had to be redesigned to accommodate the new systems, and a heavier recoil absorption system had to be designed as well, however the reduced recoil length offered by the new mount allowed for the breech of the weapon to be set farther back in the turret then previously possible, allowing greater balance of the main gun and a limiting of the affects of such a long barrel. The 7m long barrel itself has been redesigned using much more compatible materials for construction and duration, allowing for a much stronger barrel then previous. That, coupled with the mounting farther back, has allowed the G model to retain it's high degree of accuracy while on the move, as well as avoid common problems associated with such long barrels. The Type-3700 gun is fired by a brand new electro-thermal ignition system making use of electrically generated radiation to more efficiently ignite and burn the propellant, providing an increase in energy transfer to the projectile. The Type-3700 gun provides a drastic increase in firing energy over the previous 115mm generation of tank guns, allowing greater kill ranges and greater armour penetration at normal combat ranges.

The Type-3700 main gun is fed by a two-stage Type 998-X16C autoloader. The autoloader consists of two separate storage systems for propellant and projectile, allowing maximum safety while the use of more compact two-piece ammunition allows a reduction in space concerns both during storage and after firing the round. The first stage of the autoloader is the carousel ring inside the hull below the turret ring which stores thirty-five An-1100 series 140mm projectiles in an upright position within individual protected container along the primary carousel ring. An additional five rounds are carried along an inset to the carousel system at the forward part of the tank which can be automatically cycled into the main carousel line by the computer. A round is loaded into the main gun by way of an articulated lift arm at the back of the turret which lifts the round from it's container and rotates it ninety degrees to be level with the gun breech. To load a ram arm in the bustle of the turret forces the round and propellant charge into the gun, with the lifting arm acting as a bridge. Propellant stages are kept in the turret bustle behind an armoured bulkhead and access door. The charges are kept within individual armoured containers along a chain-style autoloader system. The bustle holds forty propellant charges which work with all An-1100 series ammunition. The system is fully electric in operation, and manual backups are provided to cycle the charge and projectile racks for manual loading if necessary. Blow out panels are provided for the bustle storage system. The entire system provides rapid fire capability for the tank, allowing cycle times averaging five seconds. Rapid cycle capabilities of the autoloader system far outweigh its inherent complexity, allowing the MCA-7G to unload it's entire forty round capacity in three and a half minutes, an unheard of rate of fire for a main battle tank. Such rate of fire however would quickly wear out the barrel, and is only used for burst fire of three or four rounds in combat.

The G model retains the 15mm AGH-32 heavy machine gun mounted coaxially to the main gun. The AGH-32 is a dual linkless feed machine gun firing standard 15x120mm caseless ammunition. The AGH-32 is mounted to the left side of the main gun, in front of the gunner's station, and is recessed into the thick mantle with a ventilation port built into the side of the mantle near the barrel. The coaxial gun is fed by two five hundred round drum magazines located under the gunner's reclined position, with either drum able to be selected as the primary feed drum, or both may be selected to mix ammunition types as needed.

A remote weapon station is installed just to the rear of the commander's cupola and slaved to the commander's independent thermal/optical sight. The RWS mount includes a box launcher for two 70mm class heat seeking light anti-aircraft missiles which can be targeted using the commander's independent thermal viewer. The box launcher may be removed as necessary, and can be quickly reloaded by pre-packaged 70mm tubes. The 7.5mm medium machine gun which the RWS mounts standard is derived from the AGS-5 light machine gun with a heavier barrel and is fed by a linkless belt feed drum situated vertically behind the tank commander in the turret.

The MCA-7G additionally comes with a 50mm light adjustable velocity automatic mortar mounted in the rear of the turret bustle. The mortar is fed from two twelve round linkless chutes, allowing a maximum of twenty-four bombs to be carried. The mortar is designed to provide adequate anti-infantry capability at close ranges, with it's ability to angle as high as 90 degrees, as well at standoff ranges out to 3000m when the main gun would not be practical. The system is capable of firing illumination flare rounds and smoke bombs, but is most commonly loaded exclusively with high explosive fragmentation.

Protection:

The armour scheme of the MCA-7G is almost identical to the previous B model, with the exception of more effecient primary bricks designed for the armour. The armour is designed modular around a three layer design. The only signifigant change to the basic armour pattern is the redesign of the interior "hard blocks" which make up the majority of the protection. Each block is, in essence, a titanium shell lined internally and externally with reenforcing high performance polyethylene to provide structural strength even under extreme stress. The interior of the block is filled with a ceramic-metalic material laced with tiny glass fibers for strength and added aggregation as needed. The ceramic-metalic material, developed in secret by Nineveh Armour Works, provides excellent deformation of explosively formed penetrators and other shaped charges, especially in conjunction of the other layers of the armour's system. Additionally, each block contains a pair of crescent shaped depleted uranium bars running lengthwise, suspended within the ceramic-metallic material and coated with copper. The depleted uranium bars are designed to provide complete and overlapping cover of the front and forward cars of protection at all normal strike angles in regular combat. Blocks designed for use in the rear and rear-sides of then turret, as well as the rear half of the vehicle however do not have the depleted uranium inserts.


Pictured: Diagram of the basic structure and workings of Shukur ERA.

Additionally, the G is designed to be equiped with Shukur, or "Lance" explosive reactive armour. The Shukur ERA design works by including a series of small, simple, shaped charge warheads aranged at an angle upwards of the ground but offset from the slope of the base armour by some degrees, depending on the slope of the armour. The system incorporates ignition plates offset to the shaped charge modoules such that a line drawn directly from the middle of the chaped charge heading out would line up through the middle of the ingition plates. The system is designed such that when a penetrating threat penetrates the external ignition plate and makes contact with the internal one it sets off the coresponding chaped charge. The resulting deatonation propelles a molten metal jet, as formed by the shaped charge, towards the threat object, either destroying it or severely disrupting it. The Shukur system is compact, light weight, and safe for nearby unarmoured vehicles and personell, and is avalible in a wide range forms for various parts of the G chassis. Additionally, the Shukur system is capable of excellent protection against both chemical energy threats in the form of High Explosive Anti-Tank, or kinetic energy threats such as long rod penetrators. The Shukur ERA system adds, depending on where it is placed and the angle it is placed at, between six hundred and eight hundred milimeters worth of additional RHA equivilant protection. Unfortunately, due to the nature of the design, the Shukur modoules can not be placed on every surface of the tank, and are often situated around the front and side of both the hull and turret. Top mounted Shukur modoules are avalible for the turret roof od the G model however, but they only provide protection directly over the crew compartment.

The Enlil APS was also updated to Type-2 standards, with new detection systems and soft kill systems added. Amongst the many improvements and additions to the Enlil system was the addition of two pulsed IR lights mounted on the mantlet that assist in the disruption of first and second generation anti tank guided missiles, as well as make the entire vehicle somewhat harder to distinguish through some sensors from the right angle. Further the Type-2 added a two-stage laser soft kill system designed to track and then disrupt enemy optical systems. Finally the hard kill componant of the Enlil was upgraded, with the detection, processing, and execution systems all getting a major upgrade to their capabilities, allowing the Enlil APS to engage incomming shaped charge warheads in the form of both missiles and tank fired rounds, as well as engage tank fired kinetic energy rounds.

The grenade dispensation system of the MCA-7 was replaced with an aerosol dispersion system. The areosol dispersion system can cover the forward arc of the vehicle in an aerosol formed screen, limiting the effeciveness of both laser sighting, regular and IR imaging systems. The aerosol system is controled manually by the commander, and has enough shots to completely disguise the tank seven times. The downside to the new aerosol system is that it also blocks the gunner's ability to fire back on an enemy vehicle, however the use of the milimeter wave radar system within the fire control system reduces this limitation somewhat.

Although not entirely for measure of protection, structural aspects of the hull of the MCA-7G were redesigned, or created anew, to provide a much stronger chassis. Strong reenforcing aspects of the chassis along the front of the hull and fenders, as well as along the rear of the hull and fenders, allow the vehicle to put great strain on the chassis if needed, and protect against impacts from objects such as trees. The reenforcements were designed to allow one G model vehicle to push another free if stuck, or to otherwise assist another damaged tank. Additionally the reenforcements have found use in removing objects from the vehicle's path, including concrete anti-vehicle barriers, telephone and light poles, and trees.

Systems:

Internally the MCA-7G is almost a completely new vehicle. a completely new fiber-optic based fire control system has been designed and installed, named the Gagsisa Type 1, the new system provides extraordinary computing capabilities and speeds for a package better suited to the internals of the vehicle. The Gagsisa system includes a digital all weather day/night sighting device for the gunner which may be accessed and operated from the commander's station, as well as a backup optical sight. Input systems include a manual input interface for both the gunner and commander if nessecary, as well as automatic environmental sensors, a two-mode laser range finder, and a new milimeter wave radar system. The two-mode laser range finder can be operated in a pulsed mode or in a constant stream and is capable of being used to paint an enemy target to assist guided missile variants of the An-1100 series tank rounds. The milimeter wave radar system is slaved to the fire control system and is designed for operation in situations where the laser range finder and stadard detection gear will not work. The milimeter wave radar system, although short ranged out to a maximum of three kilometers under ideal conditions, is capable of cutting through IR and laser disrupting smoke and aerosol screens with ease. Further, a small milimeter wave radar system was installed within the lower front hull to provide the driver control system with time-ahead information regarding the terrain, allowing the new suspension to be adjusted automatically by the computer for maximum stability at speed over terrain. A prototype MCA-7B retrofitted with the new system for testing was able to land all shots fired on a remotely opperated target vehicle from two kilometers using An-1000B kinetic energy rounds while moving at top cross country speed.

The crew is equipped with a full array of digital systems, including key backups, in a user freindly environment. Individual air conditioning is provided within the sealed vehicle, allowing comfortable opperation even under NBC conditions. An overpressure NBC system and air filtration system are standard. Additionally each crewmember is provided with an adjustable seat, angled within the vehicle depending on the crewmember it is placed for. The driver's seat is reclined, with an adjustable angle to allow the driver to sit up comfortable while driving with the hatch open. The gunner's seat is permenantly reclined, with comfort-specific adjustments avalible to the gunner, allowing maximum stability and comfort within the vehicle, as well as nessecary room to stretch, despite the cramped quarters. The commander's seat may be raised or lowered both manually and through an electric actuator system to allow the commander to raise or lowe his seat and view from outside the hatch as needed, or recline his seat as needed. All three crew seats are provided with storage spaces for personal items and canteens. Each crewmember is additionally provided with a hot and cold water outlet from the vehicles internal tank, allowing abundant ammounts of drinking water for mandatory consumption or for drinks like tea.

The driver is provided with a completely digital touch-screen engine managment suit, alongside the standard controls. From here the driver can view and to a small extent manage the engine, drivetrain, and fuel vitals. The driver can additionally shift the balance of fuel in the vehicle's tanks if needed, or pump fuel to another vehicle if connected to do such. The driver has a yolk style driving column with hands-on control layout for the automatic transmission and other small items such as lights and turn signals. The driver has three electro-optical periscopes feeding into three adjustable screens providing day and night viewing capability, as well as a rear-mounted electro-optical camera which can be viewed within one of the primary screens if nessecary. The periscope complex, as with the other periscopes, can be switched from electro-optical to the backup standard optical periscope simple by folding the small screen up and away.

The gunner is provided with a trio of adaptable touch-screens for managment of ammunition and the fire control system. The gunner's digital sight allows all weather operation, and may be switched between day and night modes, as well as set to display information from the much less capable milimeter wave rangefinding and targeting system. This allows the gunner to, in times of extremely low visibility which even standard IR and laser systems can not operate, fire upon enemy tanks. While not as accurate or capable as the standard system, the use of the milimeter wave radar system for targeting allows the crew slight advantage in ultra-low visibility situations. The gunner's control column includes a toggle to switch the FCS between operating the main gun, the coaxial machine gun, and the light mortar, with the system automaticly adjusting to the ballistic qualities of the differing weapons systems in relation to the ammunition chosen and the outside environment. Ammunition os selected via one of the three touch-screens.

The commander is provided with a two-tier visual suit for enhanced capability. Eleven digital screens surrounding the driver provide panoramic day and night views from sixteen well protected external electro-optical periscopes. Like the driver's periscopes, if nessecary the digital aspect of the system can be bypassed and the gunner and commander can make use of the sixteen periscopes as standard. Additionally the commander has a touch-screen display for the battlefield command and control system and controls for varios other duties, many of which can be displayed on the viewing pannels.Additionally the commander's hatch has a built in rotating system including six small standard periscopes, and the commanders independent viewing system for both day and night use. The commander needs only to twist this rotating element and designate a target for the gunner with his independent sight, allowing true hunter-killer capability. The design of the external hatch as well accomodates limited viewing through a slightly raised hatch without the need to fully open the hatch.

The combined electro-optical periscopes provide superior visual capability to the tank crew and especially the commander, while not compromising the nessecary standard periscope systems. The system consists of a standard laser-protected armour periscope with an additional level of a wide-angle high definition digital camera feeding an internal viewing system, allowing excellent under-armour viewing capability at day and night.

Mobility:

The most drastic structural change to the vehicle would be in the form of a complete overhaul of the suspension design, replacing the older eighteen roadwheel assemblies with twenty four interleaved roadwheel assemblies, provided with twelve torsion bars per side. The internals of the new suspension system were almost identical to those of the baseline B series, with the exception of more torsion bars and the replacement of the older hydraulic actuators with smaller and more powerful electrical ones. The new suspension system allows a lower ground pressure, essential for such a heavy tank, as well as allowing the vehicle to take advantage of terrain forms, and manipulate it's own mobility as needed. The adjustable suspension height allows the vehicle to lay almost flat against the ground, providing more sirface area on softer terrain by use of the belly of the hull itself, allowing the MCA-7G to be used in desert areas with somewhat softer sands then most armoured vehicles can manage, with somewhat reduced mobility. Additionally the suspension can be adjusted to take advantage of landforms to create hull down positions, or to allow the main gun to be lowered or raised a little bit extra.

The MCA-7G is powered by a modular mobility pack installed in the rear of the vehicle. The mobility pack includes the engine and limited fuel and water systems, as well as the hydraulic transmission and all protected lines. The system allows rapid change of the engine and transmission in as little as twenty minutes with the assistance of a crane, and also allows the high-pressure hydraulic transmission system to be isolated from the rest of the vehicle for safety reasons. The chassis is designed to accecpt the modular mobility pack and hold it securely in place, providing all connections in easily accessable areas behind the turret and under the turret bustle area.

The Guarita DO86-2T00 engine installed in the G is an upgrade of the former DO86-2S99 engine fitted to the B. The DO86-2T00 is a revolutionary advance in the standard engine, keeping the stadard engine block system of the DO86-2S99 and most of the internals. The primary difference comes from the new higher-flow and strength air intake system combined with a brand new variable turbocharger system. The new turbochargers are designed to provide high pressure through the high flow intercoolers of approxemetly 10 bar, allowing the engine to take full advantage of it's strong high pressure internals. The ability to run turbochargers as opposed to the superchargers needed previously has come about as a result of combining the previous gas turbine UAAPU with the engine system itself. While still providing the duties of the AUAPU, the new gas turbine is designed to provide the turbine pressure direct to the turbochargers of the engine, providing a constant flow of high pressure air into the engine and eliminating the need for the hot start capability of the B. This allows higher power to be acheived, and exceptionally higher torque, while maintaining the engine's other qualities. The gas turbine does not eat any more fuel as it is simply a redesign using the original system. Still retaining the Crower six cycle design and the water reclamation in the redesigned exhaust systems allowing the engine to recycle the water it uses to keep internally cool. The power requierments for the engine were enormus for a number of reasons, including the ability to power all systems in the vehicle. With the multitude of electrical systems within the vehicle, from electric actuatated adjusted suspension to the digital displays for the crew and the entire FCS including the gun itself, the MCA-7G is a power hungry beast. Additionally, the hydraulic transmission system aids in mobility, crucial to such a heavy vehicle. The transmission runs off solid-line hydraulic pressure lines with pressure provided directly by the engine. This allows the engine to run at optimal operating speeds constantly while providing maximum power and torque as needed, drasticaly increasing fuel effeciency overall. The system allows high average ammounts of power and torque to the tracks, allowing the heavy G to be exceptionally mobile. The transmission as well can, if needed, transfer power into torque if nessecary, allowing the G series to act as a buddy recovery vehicle by pushing other tanks out of areas they may have become stuck. The extra torque, which is automaticly controled by the drivetrain managment sensor which adjusts the transmission as needed, also allows the G to force it's way through more solid obstacles such as trees or anti-vehicle concrete barriers if nessecary, but with strain to both the chassis of the vehicle and the drivetrain.

The gas turbine auxilliary under armour power unit has been kept from the B model, allowing hot start capability with the engine. Other upgrades more easily noticed on the new MCA-7G include the installment of a built in dozer blade under the front hull to facilitate self digging of entrenched postsions. Coupled with the advanced adjustable suspension, this device will allow the quick preparation of defensive postsions in the event the MCA-7G should need to. Additionally the external fuel and water tank system was redesigned, with a close fitting water tank installed to the rear of the vehicle and able to be easily removed. A pair of larger, three hundred liter capacity, fuel drums have been hung from the external water tank on quick release system, allowing greater range then the older system, while still providing the safety of being dropped when nessecary. Finally an improved cooling system, tied to the fire control system's environmental sensors, was installed, allowing the vehicle to better control both the engine exhaust temerature and vehicle temperature in regards to the surrounding area. Coupled with the use of more modern heat release dispersion and semi radar absorbant camofualge netting the MCA-7G is set to be one of the hardest to detect armoured vehicles around under limited visibility conditions such as those seen at night, within sand storms or blizards, or within fog.

PIV-28 Armoured Infantry Vehicle - Avalible for Export

The Dictorial Republic of Sumer has seen fit to offer for export the latest addition to it's armoured forces. The PIV-28 is an advanced heavy armoured infantry vehicle which is designed to provide protection and mobility on par with the MCA-7 series vehicles, while also providing transport and firepower to a squad of infantry.

Click to view image

About:

The PIV-28 was developed to replace the aging PIV-64 heavy armoured personnel carriers now being replaced in Sumerian service. The basic PIV-28 is a modified MCA-7B chassis with the turret removed and the hull built up slightly to accommodate room for soldiers and equipment. The design retains the heavy armour of the MCA-7B, as well as including some additional rear-side, roof, and belly armour while sacrificing some rear armour. The design is intended to keep in close support of medium tanks on the battle field.

To make room for personnel and a passage for personnel to exit the vehicle, the original DO86-2S99 engine of the MCA-7B has been replaced with a much smaller DO66-2S00 engine producing 1800 brake horse power. The transmission is a slightly smaller version of that used in the MCA-7B, and has been moved forward to drive the new forward mounted drive sprocket. The engine, still mounted in the rear to the left side of the hull, provides hydraulic flow for the engines the same way as in the MCA-7B, with the exception of a longer armoured piping system being installed and running along the inside of the left side of the hull. The right side of the hull has been modified to allow for passage of infantry from the main central compartment.

The vehicle has a crew of three, with the driver up front in the centre, and the commander to his left and rear, and the gunner to his right and rear. The internal crew compartment is very low and not designed for soldiers to freely move around in. The crew compartment of the Armoured Infantry Vehicle variant also carries seven infantry who occupy low slung padded folding seats in the middle area of the vehicle. Four infantry are seated in the middle of the vehicle facing outward, two per side, with ammunition storage provided between the seats and an individual periscope and hatch provided to allow firing outside of the vehicle or quick dismounts out the top. Additionally two more infantry occupy seats against the hull of the vehicle, facing inwards, one on each side. These two seats must be vacated and folded for the other four seats to be vacated. And finally a seventh automatically folding seat is provided within the exit passage facing rearward towards the exit ramp. This final seat is spring loaded to retract quickly as soon as vacated so as to allow easy exit of the vehicle, and is placed within the passage facing rearward to allow for operation of the vehicle with the exit ramp down or partially down while maintaining a comfortable position for infantry to fire out.

Other variants of the PIV-28 include a command and control vehicle outfitted with electronic communications and mapping equipment for battlefield management, and an armoured supply carrier which can carry four tonnes of cargo internally.

PIV-30 Armoured Infantry Combat Vehicle

Click to view image


About:

Developed to augment the PIV-28 in Sumerian armoured formations, the PIV-30 is a development of the MCA-7G chassis and components. The PIV-30 uses the same modifications done to the MCA-7B to create the PIV-28, with some modifications to the layout. The engine is still mounted rear left of the vehicle, with the disembarkation corridor and powered ramp to the right of the engine compartment. An upgraded version of the DO66 engine is provided, using the same ultra-high pressure turbocharger technology for compact power. The fighting compartment is where the differences really show, with the PIV-30 being rearranged to seat seven armoured infantry as well as mount an unmanned turret and ammunition.

The new turret is mounted offset of centreline to the left side of the hull, with it's main armament being a 50mm compact automatic cannon offset to the right of the centerline of the turret, providing it with a centerline view of the chassis. The new turret is armoured enough to protect it from light auto cannon fire, but not as heavily as the chassis. Armament is the new compact 50mm automatic cannon which fires the caseless 50x300mm telescoping ammunition loaded into a drum magazine below the turret inside the fighting compartment. An additional AG-12 7.5mm machine gun is mounted coaxially with 2000 rounds of ammunition loaded within the turret bustle. A four-tube multipurpose recoilless weapon launcher system is provided slaved to the main armament and mounted on the right side. The four vertically stacked tubes provide capability of firing any number of unguided rocket propelled infantry weapons, as well as standard Sumerian 130mm diameter anti-tank guided missiles, and light man-portable surface to air missiles. The fire control computer of the turret allows it to operate all options at once, or independently, and to engage both ground and airborne targets.

The passenger compartment has been redesigned with low-slung folding seats mounted along the hull of the vehicle on either side facing inward. Seating for seven infantry is provided with two sitting on the left side facing inward, and three sitting on the right side facing inward. An additional seat is included within the dismount corridor as in the PIV-28, and a rear-facing seat is provided just forward on the left side next to the turret. All three crew are seated forward. Hatches are provided two to the left side, and three to the right, with one on each side being equipped with a pintle mount for an AGS-5 machine gun. All hatches are provided with day-night observation periscopes. All seats along the right side, and the dismount corridor seat, are spring loaded as in the PIV-28.

The PIV-30 is designed to augment the capabilities of the PIV-28 in armoured formations, providing a hard hitting infantry fire support vehicle for armoured infantry formations, and allowing the armoured force more flexibility.

TD-7 Self-Propelled Gun

Click to view Image

About:

The TD-7 is a self propelled gun based on the MCA-7G chassis designed to replace the MCA-3 based TD-5 as the primary assault gun and tank destroyer attached to Brigade sized units. The TD-7 is a complete ground-up design based on the MCA-7G chassis, with no relation to the previous TD-5 or the TD-6 concept vehicle outside of intended role. The role supported is that combined of heavy assault gun for direct-fire support of higher-caliber weaponry then the MCA-7G can allow in support of the infantry, as well as long-range heavy anti-tank firepower to armoured formations. Deployed only in Brigade and Legion formations, the TD-7 is one of the heavier guns available to mobile armoured formations.

The TD-7 makes use of the armoured layout of the MCA-7G, providing a high protection, highly mobile, gun system. The armoured protection of the MCA-7G is retained, with the interior layout of the vehicle being shifted. The engine is rotated 90 degrees and placed in the forward section along the left side of the vehicle, with the driver moved to the right. The transmission is placed in the direct front of the hull, ahead of the engine. This layout removes the modular nature of the power train, requiring now more time to remove the necessary plating above the engine to access it. The movement of the engine allows a much larger volume for the fighting compartment now at the back of the vehicle, facilitating a new Type 1000-X19A autoloader which provides full load access to the 28 rounds carried. The vehicle is designed to carry a various assortment of 180mm rounds, with a total of 28 rounds carried stored in the autoloader in the hull. The main gun is the Type-3800 180L50 smoothbore gun, an enlarged version of the Type-3700 140L50 smoothbore found in the MCA-7G. The gun fires similar two piece ammunition, with a standard 180x1000mm projectile size capability, and a gel-core caseless propellant cartridge of the An-1120 family. The main gun and autoloader are capable of a burst fire rate of three rounds in twenty-four seconds, and a sustained rate of three rounds per minute as ammunition lasts. A version of the liquid cooling system of the thermal sleeve is carried over from the Type-3700. The TD-7 makes use of a modified MCA-7G mantle to accept the new gun with a heavier mounting, as such the 15mm HMG is carried over as coaxial to the main gun. Provisions for a light remote weapon station in the casemate roof are also included to mount a 7.5mm machine gun, and this mounting is almost universally used. The main gun is mounted on a semi-fixed mounting allowing traverse of ten degrees to either side of centreline, a maximum depression of five degrees, and a maximum elevation of thirty degrees. The use of the MCA-7G's electro-adjustable suspension allows this to be raised to as high as forty-five degrees, and as low as twenty degrees depression. The main gun is tied to a fire control system derived from the MCA-7G, without any serious ability to fire on the move however. The millimeter wave radar system has been removed as well, with indirect fire capability being added. Additionally an expanded Enlil Mk.II system has been included, along with a larger aerosol grenade dispenser, both moved to the hull sponsons and alligned to fire in a spherical arc around the vehicle in a vertical form. The crew of two are positioned in the right forward section of the hull, with the casemate unmanned. The crew includes a driver, with the commander seated behind him, both with access to the gunnery controls of the fire control system.

The TD-7 is accompanied by a PIV-28D Gun Supply Vehicle, with a further two crew, allocating four crew per gun. The TD-7 system is designed to accompany armoured brigades as an integral company level. Each company consists of twelve guns, twelve support vehicles, and a trio of command vehicles, and can operate both in the indirect fire artillery role, the direct fire assault gun, and the direct fire tank destroyer roles.

ADTV-7 "Kissa" Combat Air Defence Vehicle
Click for Image

About:

The ADTV-7 is an air defence system designed to provide Regiment level air defence to armoured formations in the Sumerian Armed Forces. The system is a complete turret system designed to replace the existing turret on an otherwise unmodified MCA-7G chassis, allowing for maximum compatibility with the MCA-7G and minimal maintenance needs. The vehicle includes all necessary electronics and scanning equipment, as well as ammunition and weapons for providing low level air defence. The vehicle may also be used effectively against ground targets due to the targeting system's multi-use aspect, the nature of the main guns, and the provided multi-use missile tubes.0

The main armament of the ADTV-7 is a pair of 35mm ATG-350L100 auto cannon which can provide a combined burst rate of fire of 3,600 rounds per minute. Each gun is fired from two five hundred round drum magazines through a linkless dual-feed system providing for two different ammunition types to be carried. Standard load is often a mix of 10% frangible armour piercing, 40% high explosive tracer, and 50% high explosive incendiary rounds per drum, allowing multiple targets both in the air and on the ground to be engaged as needed. The guns have an effective engagement range of 5500m, and are computer limited to either 90 or 300 round burst fire to prevent overheating. The ADTV-7 is also fitted with four 200mm multi-use launch tubes, similar in design and purpose of those fitted to infantry fighting vehicles, that provide for a variety of rocket assisted, and recoilless weapons to be used. The tubes can fit standard 130mm Sumerian ATGM packages, a single uiguided high explosive 150mm rocket, four 70mm or a single 130mm surface to air missile package, or a prepared pack of seven 50mm unguided rockets for use on ground targets. An additional four storage tubes are provided in the rear of the turret for additional packages which must be manually reloaded.

The ADTV-7 relies on a complex digital fire control system based on the fiber-optic based FCS of the MCA-7G. The system consists of a Type 310RS X-Band AESA radar which folds down behind the turret when not in use and provides a tracking range of at least 24km and a minimum altitude of 15m with excellent resolution and identification. The Type-310RS can track and identify up to sixty four targets at once in independent operation, and is capable of operating with up to four other ADTV-7 systems as part of a networked air defence unit. Once a target has been identified and selected by the vehicle gunner, the tracking system takes over. The tracking system consists of a single Type 412 Ka-Band AESA radar with a range of 18km and a suite of counter ECM systems, a laser range finder and target designator, and a thermal imaging/digital optical system which allows the ADTV-7 to track targets on the ground or in the air in all weather and climate conditions. The ADTV-7 is capable of engaging targets flying as high as 5km altitude, and as fast as 550m/s. Gun/missile elevation is from -10 to +85 degrees, and the turret can turn the full 360 degrees. Maximum engagement time is approximately 6-8 seconds. The ADTV-7 is fully capable of firing on the move.

TLB-18 Tank Launched Bridge
Click to view image

About:

The TLB-18 is an armoured vehicle launched bridge (AVLB) based on the MCA-7G chassis to provide exceptional mobility to MCA-7 based forces. The vehicle consists of a standard MCA-7G chassis with the turret and integrated dozer blade removed, replaced by a special bridge carrying system and a forward anchor blade. The vehicle is has a crew of two, a commander and driver, and is fully able to keep up with armoured forces based around other versions of the MCA-7 chassis. Because of the large nature of the bridge vehicle as well ballast, in the form of an improved belly mine protection plate has been added to the underside of the vehicle.

The bridge is a 110 tonne class bridge providing carry capacity for all vehicles within the MCA-7 family. The bridge is made of welded titanium and is twenty-six meters when extended for use. A gap of twenty four meters, with a one meter step on each bank, can be crossed at an efficient speed with vehicles under one hundred tonnes. The vehicle includes an anchorage blade at the front which is lowered to provide anchorage as the bridge is extended and lowered. The turret rotation mechanism of the MCA-7G is retained somewhat allowing the TLB-18 to adjust bridge launch angle as necessary over the forward twenty degrees of the vehicle, allowing more flexibility in bridge laying. The bridge can be launched and retrieved in less then five minutes each way.

MCA-7B "Ubara Tirak" Medium Battle Tank
Click for Image

Prmary Design Stages:
- MCA-7A: Initial Prototype Variant. Retired.
- MCA-7B: Primary production variant. In Production.
- MCA-7C: Export Variant. In Production.
- MCA-7D: Rebadged MCA-8. Under Development.

Basic Design:
The primary design of the MCA-7 series of vehicles is to provide the Sumerian Republican Guard with a highly protected, highly mobile, and highly efficient armoured killing platform for use both at home and abroad. As the latest incarnation of the MCA program, it is designed to engage enemy tanks in combat, with limited self protection from infantry as an adverse side effect. The nature of the terrain in and around Sumer forced designers to approach a slightly heavier design with thicker armour on the sides of the hull and turret to facilitate maneuvering in the open savanna that this vehicle would most often be encountering. While the resulting vehicle is able to operate in a limited fashion within mountainous and jungle terrain, the home terrain, as it would be, of this vehicle was deemed more to be the open fields and deserts. Thus care was taken to design a vehicle that would not compromise it's ability to operate effectively in the terrain of choice just to provide a more multi role oriented vehicle, a failure that befell the MCA-5 and MCA-6 earlier.

The hull layout of the MCA-7 series follows the standard Sumerian tank design since the MCA-4 program, that of a base structural armour with added on modular armour components to provide highly replaceable strength. Construction is done mostly of titanium alloys which are more widely available within Sumer then steel materials. Composite materials and synthetic fibers, as well as ceramics are also used heavily.

Power is provided by the new Guarita DO86-2S99 engine and accompanying transmission system, designed in a modular power pack that can be completely removed and replaced quickly in the field with minimal time, and if needed with no lifting crane. The vehicle is equipped with hydraulically adjustable suspension over a large number of small road wheels to lower the ground pressure as much as possible. Wide seventy two centimeter tracks are provided as standard to ensure the vehicle the ability to move through all terrain.

With a large 115mm smooth bore anti tank cannon and supporting machine guns and grenade launchers, as well as an effective armoured protection system the MCA-7 series was designed to be a force to be reckoned with for many years to come on the battlefield. The digital fire control system allows accurate fire from the main gun while moving out to as far as five kilometers. Additionally, advanced optical systems allow the commander and driver greater views of the battlefield around them, providing increased tactical mobility for the vehicle.

The MCA-7B has, overall, exceeded the design requirements for the Sumerian Republican Guard for their next generation medium tank, and has found a welcome home within the Temple Guard as well. As an effective fighting platform and tool, the MCA-7B has earned welcome respect within the Sumerian Armed Forces.

History:
Work on the MCA-7B program began shortly after the MCA-7A finished production. The A model was quickly found wanting in several areas when put into direct low intensity combat usage on the North-Western border. Engagements with numerous opposing armoured vehicles showed that while the A was satisfactory in its design features, it would soon be lacking when brought to bare against modern systems coming out in the near future. Thus a five year improvement development plan was put in effect by the Republican Guard to improve upon the A model in the near future. With detailed evaluations and reports on the performance of the A model and its features coming in almost daily the number and extent of improvements to the basic A design was showing. Within a year the Republican Guard Armour Standards Committee (RGASC) had compiled a list of required performance characteristics which the new model, designated the MCA-7B, would have to meet. The design requirements were shown to the Office of the Dictator, which approved the project for development, and then to the Civil Senate, which after a vote approved the funding needed. Design elements were quickly sent out to various production facilities to be designed in conjunction with the main vehicle components at the Nineveh Armour Works.

Among many design improvements, the pressing need for a more powerful main gun was foremost in the design features. Various approaches were tested to improve the 105-85mm tapered smooth bore of the A model with no success. Eventually more traditional 120mm, 125mm, 130mm and even 135mm smooth bore guns were tested, but again these projects were considered unsuccessful. Armour protection was also a major complaint from field reports, with the protection quality coming under serious question. The final nail in the coffin of the A series was the power plant, which was deemed too heavy and bulky to be effective within the vehicle. Different combinations of various alternative systems were tried, and the resulting nine first-run prototype test vehicles were put through combat trials outside of Nas-Arabeh on the 14th of Simanu, exactly three years after the project had begun. After three weeks of combat testing against each other, the MCA-7A, and several foreign vehicles of expected similar capabilities, all but three of the prototype combinations had been found to be unusable. The three remaining prototypes, BP2, BP5 and BP9, had all unfortunately broken down during the trials as well due to track failure. As all the prototypes used the suspension, road wheels and tracks of the MCA-7A, the order was added to the design requirements for a new track and suspension system.

With lessons learned from the Nas-Arabeh trials, and with neither of the three acceptable prototype designs completely fulfilling the design requirements, the project team returned to Nineveh and began work on the second series design prototypes which were to incorporate features of all three prototypes. Within a year a further three prototypes were under construction, designated BP10, BP11, and BP12. The three second series prototypes were identical to each other, with specific design features now settled on a prototype systems coming in from the affiliated production facilities. Two of the prototypes, B10 and B12, were put through combat rigorous trials outside of Nas-Arabeh again, and then quickly sent to the North-Western border for combat trials. The third prototype, B11, was demonstrated to the Office of the Dictator, representatives from the Civil Senate, and members of the RGASC outside of Nineveh. Following combat reports and the successful demonstration outside of Nineveh, the Office of the Dictator approved a slightly amended design to the second series prototypes for production as the MCA-7B. Production started in Tebetu of the year 10,118, with the first units delivered in secret to the Inanna Temple Guard Regiment by mid-10,119. Increased demand for the MCA-7B has led to increased need for production, and sixteen new manufacturing plants have since had to be constructed to facilitate the demand. Additional production is now avalible, as current goals are being met and exceeded.

Protection:
The armour layout of the MCA-7B is a radical change from the previous MCA-7A and MCA-6 series tanks in that it uses two to three layers of supporting armour types to provide maximum protection, a system inadvertently built into consecutive upgrades to the venerable MCA-3 series of tanks. The armour is, at it's base, an alternating series of solid titanium alloy plate and titanium alloy “box” plates which are made up of a honeycomb like mesh of titanium alloy encased in a titanium “box” like shell. The internal structure, at it's thickest, contains two “box” sections sandwiched within three thick titanium alloy plates to provide a strong and rigid base that is still light weight.

The secondary layer of the armour consists of modular blocks of ceramic-metallic material encased within a titanium alloy shell. Within the ceramic-metallic material are rigid depleted uranium sheets, each a hemispherical shape with the outer curve pointing outwards from the vehicle, set to provide as much overlapping cover of high density material as possible. The ceramic-metallic material is further reinforced through the impregnation of randomly positioned carbon nanotubes throughout the material, in a similar way to the way glass or carbon fiber is used to reinforce plastic. Such carbon nanotubes are produced through simple flame method, and are highly irregular in both size and quality, but add greater strength to the ceramic-metallic integrity then conventional glass, carbon, or synthetic fibers. The ceramic-metallic material is further encased in several layers of resign impregnated sheets of woven high performance polyethylene layered in interlocking and alternating patterns to provide excellent integral strength to the ceramic-metalic material, and together with the loose fiber reenforcement, keep the ceramic-metalic material from shattering, thus allowing it to absorb multiple rounds before failing. These second layer modules are layered in two alternating layers ontop of the structural componant of the armour to provide as few areas for penetration as possible. Each module is custom shaped and constructed for the vehicle, and varries in thickness and area covered, as well as shape, to allow maximum coverage. Modules not designed for the primary fighting arc of the vehicle, the forward and forward-side arcs, are not provided with the depleted uranium insert. Areas such as the hull and turret rear, as well as the rear-top of the hull and turret have only one layer of these modules, with the additional part occupied by integral water storage tanks formed of resin hardened high performance polyethylene, for storage of much needed distilled water.

The third and final layer of the armour is a made up of larger plates of the titanium alloy honeycomb “box” filled with a synthetic rubber material that is impregnated with loose high performance polyethylene fibers to increase strength. The entire assembly is encased in thin titanium plates and coated by several thick layers of resign hardened woven high performance polyethylene fiber sheets. This third layer is designed primarily to offer lower level ballistic protection to the vehicle within a highly modular package that can be changed and replaced as needed.

Finally the armoured protection suit of the vehicle is enhanced by the integral Enlil armoured protection system (APS), which uses milimeter wave radar and various IR sensors to detect incomming rounds and calculate their trajectory. The Enlil APS fire control system, when armeded, then automatically fires the coresponding launcher, or launchers, for the integrated 50mm defensive grenade system. The 50mm grenade system used by the Enlil APS is seperate from the defensive grenade launcher suit, and can only be fired from an active Enlil APS. The grenades themselves lob at a short but high arc, allowing them to cover essentially a sphere around the vehicle. The grenades themselves deatonate to throw a mass of high density tungsten rod fragments in the path of an incomming projectile to distroy, disable, or otherwise distort it's flight path and remove it's effective armour penetrating ability. The Enlil APS uses twenty such grenade launchers built into the turret, each firing from a nine grenade magazine, allowing the use of the system against multiple targets from the same area.

Armament:
The primary armament to the MCA-7B is the new Type-3650 115L60 smooth bore anti tank gun. The Type-3650 gun is a high velocity long smooth bore gun that uses a two stage loading round to achieve maximum power in a compact design. The Type-3650 uses the new An-1000 series of tank munitions which comprise of the projectile and the propellant as separate parts. The propellant stage is made from a compression formed and resin bonded solid propellant outer shell derived from the primary gelatin propellant contained inside. Within the outer case is a high efficiency gelatin propellant which provides greater power and a cleaner more efficient burn during ignition then conventional solid propellants. The propellant is ignited through the insertion of an ignition probe through the propellant casing to contact the gelatin primary propellant. The ignition of the propellant is done through the release of a short but high intensity ultraviolet radiation pulse into the propellant which forces the entire cartridge to detonate through chain reaction of the detonating primary propellant. This type of ignition allows for a design of the propellant which will be less likely to detonate when struck by an enemy anti tank round, as well as propellant that will burn more efficiently within the barrel reducing the amount of cleaning that must be done. Projectiles available to the new Type-3650 gun include the entire spectrum of An-1000 series 115mm rounds. Among the most promising rounds of the new series include the An-1000A Ballistic Shell Rocket Assisted Discarding Sabot Kinetic Energy (BSRADSKE) round, affectionately known as “The Thing” by crews. The An-1000A uses a new long rod penetrator design made of high density depleted uranium alloyed with titanium and molybdenum designed to provider greater penetration capability over previous long rod designs. Because of the inefficient aerodynamic qualities of the new penetrator design the round is encased in a copper ballistic shell which is designed to easily sheer off during penetration, but to increase aerodynamic efficiency of the round and allow it to hold a greater amount of kinetic energy over longer distances. The copper ballistic shell is designed to keep the overall diameter of the penetrator to no more then 34mm diameter, while providing a more streamlined flow of air over the round in flight. Stabilization of the round in flight is provided by four narrow titanium fins forward and four at the rear of the projectile, offset to provide the greatest stability over the length of the penetrator and allow greater accuracy over long range. Finally the An-1000A is equipped with a light weight solid fuel rocket motor which is designed to keep the round at a high velocity, close to that of the muzzle velocity, out to a greater distance, allowing longer ranges to be achieved. The rocket system, conversely, reduces the accuracy of the round slightly over range, however an unrocketed version, the An-1000B, is available with a more conventional kill range but slightly more accuracy out to those ranges. Other rounds available within the An-1000 series include conventional APBC, HEAT, HE, HE-Frag, Smoke, Illuminating, and APFSDS rounds, as well as the An-1000M gun fired guided missile currently under development.

The Type-3650 main gun is made from high strength titanium alloys, allowing the use of greater pressure propellants, but at a slight cost in reduced life time of the barrel. The gun itself is fed through the Type 998-X16B two stage autoloader, which uses a mixed carousel and bustle storage system within the tank to store the rounds and propellant sections. The rounds are stored individually within armoured containers around the turret basket similar in operation to older Soviet T-80 auto loaders, storing the rounds upright and ready for loading. This design feature of only the actual projectiles being stored in the turret bustle allows for all forty two rounds carried by the tank to be fired in succession quickly. The projectiles are loaded into the gun by a lifting arm which when level with the breach also acts as a bridge for the propellant pushed in from the bustle. The propellant is however stored in individually armoured bins within the turret bustle and aligned on a chain type automatic selection system. Propellant storage is separated from the rest of the vehicle by an armoured bulkhead, with blow out panels provided encase the propellant is hit and detonated. The propellant sections are fed into the gun by an electric actuator which pushes the round onto the projectile lift arm, and then forces both the projectile and the propellant stages into the gun. Although more complicated then the typical autoloader system, the Type-998-X16B allows for fast and reliable rates of fire while maintaining a high number of rounds ready to fire and providing safe storage for those rounds.

Additional armament of the MCA-7B includes a dual feed 15mm heavy machine gun mounted coaxially to the main gun, as well as a 50mm smoke and fragmentation grenade system which fires four grenades from eight launchers provided around the rank. The heavy machine gun is slaved to the main gun and operated by the gunner, but allows the destruction of light vehicles and infantry without the use of the main gun, while maintaining enough power to penetrate light walls or to reach infantry at a greater range. The grenade dispersion system is designed to give overlapping fields of fire around the tank to lay either a full smoke screen, or to lay fragmentation grenades to discourage nearby enemy infantry from approaching, the system is controlled by the tank commander, who may fire the launchers individually or in groups ranging from two launchers to all of them. Provisions for lighter machine gun mounts are provided for both the commander and gunner hatches as well, but rarely used.

Mobility:
The MCA-7B is powered by the next generation in tank engine to come out of the Guarita Engine Production Facility, the DO86-2S99. This new engine was designed specially for the B series upgrade to replace the previous Flat-12 cylinder engine in the A series, a carry over from late model MCA-6 upgrades. The DO86-2S99 is an opposed piston engine that consists of two banks of four cylinders layered one atop the other, in similar fashion to the H configuration of some Boxer engines. The engine is multi fuel capable, allowing greater versatility in the field, and compatibility with foreign fuel stocks if needed. The major design difference of the DO86-2S99 as compared to previous opposed piston engines is the use of a water injecting six stroke cycle. In this system the engine operates as a typical four stroke engine for the first four strokes, except following the exhaust stroke fresh distilled water is injected into the cylinder where the residual heat of the combustion turns the water into steam, forcing another power cycle after the combustion cycle, as well as cooling the engine. This process allows a close to fifty percent gain in fuel efficiency for a given amount of power, with the added benefits of vastly cooler engine and exhaust temperatures, as well as lower maintenance issues related to normal wear and tear from the heat of combustion.

The cylinder design of the DO86-2S99 is not a pure opposed cylinder design. The two pistons are separated by an hour glass shaped cylinder pseudo-head which contains the necessary injection systems for the fuel and water injection as well as secondary ignition systems, while providing optimum compression and flow through required for linear operation. The layout of the engine is such that exhaust from the engine flows through a central exhaust conduit inside the engine between the cylinder banks, allowing the intake systems to be more isolated from heat on the outside edges of the engine.

The engine itself is made primarily out of milled titanium, and special poured ceramic insulation. The ceramic insulation is mainly used to surround the cylinders and exhaust conduit to isolate residual heat from the rest of the engine. Milled Titanium makes up the primary component of the majority of the engine, including the block, cylinders, pistons and crankshafts. Milled Titanium is used to increase engine life and durability and strength while reducing weight.

In it’s primary configuration the DO86-2S99 uses two mechanically powered twin-screw type supercharges which take in air from the engine filtration system and compress it. The compressed air from the superchargers is fed through an inter cooler before being split evenly between the two cylinder banks through a series of pipes. Each supercharger being individually driven from one of the two crankshafts. The engine itself having two crankshafts, one per side, each running eight pistons, similar in action to a V8 engine.

At half the mass and volume of the previous Flat-12 engines, while maintaining the same power output, the new DO86-2S99 engine enabled the integration of transmission and engine into a single modular removable component of the drive train, which has greatly reduced engine change and repair times in the field.

The Under Armour Auxiliary Power Unit UAAPU of the MCA-7B uses a small gas turbine powered generator system to provide power to the vehicle while the engine is not running, or damaged. An added feature of the UAAPU is that the exhaust from the gas turbine used to generate electrical power can be ducted into the intake system of the main engine performing what is known as a dry start. The dry start capability of this system allows the use of the gas turbine's hot exhaust gases to preheat the DO86-2S99 cylinders before use, allowing much quicker start up times and faster time to power of the engine.

The transmission used is the Type-190 Hydrostatic transmission from the Guarita Production Facility as well. Using the two crankshafts from the DO86-2S99 to power two dual hydraulic pumps, each one both pushing and pulling the fluid through the system, the transmission works using high pressure hydraulic fluid inside specially designed piping to provide both electrical generation power and movement. Through a series of thick double-layer titanium pipes, hydraulic fluid flows through two input transfer pumps which transfer the energy of the hydraulic fluid to the two drive train final gearboxes. The final gearboxes are both automatically variable planetary gear systems, allowing automatic shifting as needed through six forward and four reverse gears. The use of variable volume pumps for both the input transfer pump and the push-pull power pumps allows the speed of the final drive shaft to be altered without altering the speed of the engine or the gear ratios, which allows the engine to run at optimum RPM and power output regardless of the speed of the tank. Forward and reverse gears are used to increase or decrease speed frames in both directions for the whole vehicle, while directional input from the driver changes the speed of either track to change direction. This RPM-independent power system allows the vehicle to utilize it’s full power range at all speeds, giving it superior mobility on all terrains then previous MCA generations, and indeed many contemporary vehicles.

The vehicle is suspended on eighteen road wheels through a long-arm hydro-torsion bar system. The system is based around the standard tube-over half-length torsion bar system of the A series, mounted in a semi-twisting housing that allows the whole apparatus to twist fifty degrees before being stopped by a block in either direction from a set plane. A hydraulic ram system is used to change the angle of the torsion bar assembly allowing the system to change ride height to the road wheels individually while maintaining the suspension qualities of the torsion bar system. In the event of a failure to the hydraulic system the hydraulic ram is locked in whatever position it was in at the time and left to operate as a pure torsion bar system. A pressure relief valve in each ram cylinder allows pressure to be bled from the cylinder if the weight of the vehicle is unequally shared by up to three road wheels on either side, allowing the vehicle to distribute the vehicle weight over all the road wheels available on one side evenly even if the system locks up with the suspension set to different angle planes.

Crew Systems:
The MCA-7B comes with a wide variety of advanced systems to provide both efficient execution of the crew's tasks and provide optimal comfort to the crew within the vehicle. The vehicle is equipped with, among other things, an integrated air conditioning system which controls the general climate within the vehicle as well as controlling the internal atmosphere and protecting the crew from external nuclear, biological and chemical threats. The air conditioning system is further taken to provide each of the three crew members with an adjustable climate at their station, allowing the crew maximum comfort in all temperature ranges. Additionally the use of adjustable gelatin filled seats integrated with the climate control system through the use of air tubes within the seats to carry warm or cold air from the air conditioning system and either heat or cool th seat as needed, for extra comfort and to allow the crew to operate for extended periods of time. Each crew station has additionally, enough room to provide enough limb movement to allow the crew to stretch without having to vacate the vehicle.

Additionally, a water storage system is integrated into the vehicle, as well as a water reclamation system from the engine exhaust and a filtration and distillation system to clean the water. Each crew member is provided with a variable temperature outlet for drinkable water from this system, which is also shared by the engine for it's six-stroke design. This feature allows the crews to drink plenty of water, an essential aspect of operations within the harsh tropical and desert climates of Sumer.

Fire control is provided through a digital fire control computer, and can be operated by both the gunner and the commander if needed. The MCA-7B fire control system allows maximum accuracy for the main gun, and is separate from the rest of the vehicle's systems. The commander has around his station a series of flat screen monitors providing him a day or night image of the outside through a number of carefully placed high definition and wide angle digital cameras on the turret, allowing quick observation of the surrounding terrain. The commander also retains an electrically operated rotating hatch with integrated optical periscopes for use regardless of the state of the digital optics suit. The commander's hatch also contains the combined optical and digital primary commanders sight which provides the commander with both day and night viewing through normal and IR views, as well as the ability to designate targets for the gunner quickly.

All crew controls are provided as digital, with the commanders primary control systems being through touch screen monitors. The driver and gunner however are also provided with limited touch screen capabilities for their stations, including ammunition selection for the gunner and vehicle profile and engine management controls for the driver.

MCA-7C "Timber Wolf" Main Battle Tank - Export Model
Click to view Image

The MCA-7C is an export variant of the standard MCA-7 series of tanks designed as a private venture by Nineveh Armour Works into the international market. Some key features of the C variant are visually obvious, with the engine power pack having been replaced for a simplified version of that in the B using the DO66-2S99 instead of the DO86-2S99, and the accompanying change in the external fuel tank mountings in the rear. Along with the removal of sensitive systems and the optimization of the electronics suit for the international market, the C model also does away with the heavy side armour skirts of the B, shooting for a lighter footprint thought more desirable to the international market. The new side skirts are made from two 20mm thick steel plates sandwiching a 10mm thick resin hardened high performance polyethylene fiber core, wrapped in several layers of woven high performance polyethylene fabric hardened with resin as well, the result is a strong yet light weight skirt for protection of the running gear. Additional changes to the vehicle structure include the changing titanium in use outside of the honeycomb structures for improved rolled homogeneous steel armour. These design changes make the MCA-7C lighter then the MCA-7B, and slightly more narrow as well to accommodate foreign roads and railways. Additional changes include the removal of the 15mm heavy machine gun in favor of a coaxial mounted 7.5mm machine gun, and the removal of heat reduction systems from the exhaust manifold of the engine. While the removal of these heat reducing system does make the engine exhaust hotter, because of the nature of the new DO66-2S99 the IR signature of the exhaust from the C is still well below that of contemporary main battle tanks. Running gear of the MCA-7C is also different from the MCA-7B, with the change to fourteen larger road wheels instead of the eighteen smaller ones, this step was taken to reduce the overall cost to produce the running gear as well as reduce maintenance and logistical needs of the vehicle. Final changes to the C variant include the removal of some of the bulk of the armour from the sides of the turret, further reducing the weight without compromising it's excellent protection capabilities.

Overall, the MCA-7C is an excellent option as a main battle tank to foreign nations looking for a modern, highly capable and highly mobile armoured fighting platform. The advanced digital fire control systems coupled with comfortable crew placement and a powerful gun bring the MCA-7C to the forefront of any battlefield.

Export Policy:
Thank you for considering the MCA-7C, the next generation of main battle tank, for your armed forces. While we do hope to do business with you regarding the purchase of the MCA-7C, we are required to inform you of a number of export laws in place. Firstly it should be noted that production rights are unavailable for the MCA-7C. While we realize this may inconvenience some of you, it is necessary to ensure product quality and to keep track of sales. We do offer full spares support however, with each vehicle being shipped with adequate spares for short use, as well as a signed contract for supply of extra spare parts as needed. While in buying the MCA-7C you do commit yourself to paying for future spares, the cost for such is almost negligible over the usually long service life of the MCA-7C. A second concern that must be noted is that in buying this vehicle, you agree not to steal technology within the vehicle and produce it yourself, or export it yourself. Certain technologies may be available for individual purchase, such as the DO66-2S99 engine, however we still do not allow production and export of this vehicle, in part or whole, by foreign nations. Technological theft and unauthorized export will be punished through the removal of export opportunities of the offending nation, as well as a possible declaration of war to ensure said technologies remain safe.

As a final note, the MCA-7B, currently unavailable for export, may become open for export to certain nations in excellent standing with the Sumerian government. Unfortunately, we do not keep a list, and would prefer not to be asked who such a nation may be, thus if you wish to purchase the MCA-7C and are eligible for purchase of the MCA-7B, we will inform you during the purchase interaction. Likewise some nations in excellent standing with the Sumerian government may be open to variable levels of production rights, but as with the MCA-7B, we will inform you if you are eligible for such rights.
Export for the MCA-7C is priced at $8 million USD per vehicle, and as previously stated includes spares and ammunition, as well as a spares and ammunition replacement contract. We are willing to discuss modifications for prospective buyers to facilitate greater logistical compatibility with their nation, and are more then happy to review or explain anything necessary, as well as answer any questions you may have.

To Whom It May Concern;

On behalf of the directing Board of Investors, I have been authorized to open negotiations for the purchase of 800 MCA-7E "Timber Wolves". However, I have been tasked with ensuring the following modifications to the requested systems. First, we do not require fire control, battlefield management or communication integration systems, hardware and software, as we have developed our own proprietary systems we feel can be successfully adapted to suit your weapons platform. The necessary wiring would be appreciated however. Secondly, the Enlil APS will also be unnecessary as we have proprietary technologies that can serve the same purpose. Necessary mountings and wiring would be appreciated, but we will provide our own hardware. My superiors have authorized a starting bid of 8bn USD for the order to take into account the lack of effort intensive computer systems and software development. We look forward to employing your weapons platform in our future operations.

Sincerely,
Robert Flanders, Director of Product Acquisition.

[Turkish Federation]

We, Ministry of Defence of the Turkish Federation, would like to purchase the DPRs of:

- the MCA-7E, for $2 trillion
- the An-1100G, for $1 billion
- the PIV-28, for $400 billion,
- the PIV-30, for $600 billion,
- the TD7, for $700 billion,

Total price: $4,7 trillion.

Realizing our defence budget is exceeded by the total cost of this order, we would like to pay in 10 installments for 10 years ($470 billion/year).

[Dostanuot Loj]

To Robert Flanders

With eight hundred vehicles lacking all computer systems, as well as the APS, we can accept this. This does not, of course, include drive train management systems, which we would be ill advised to remove.

From: Farrell Norton
To: Nineveh International Export Division

Dear Sir,

Our armored formations have long looked up to the products of the Nineveh Land Systems, as the most proven and sturdy tanks available on the market. Unfortunately, the procurement used to be out of the question, as a tank wider than 3 meters would be unable to fit through even the best of our roads.

Lately, however, the growing tensions in Haven and the open warfare have forced our company to adopt a more active foreign policy, which involves remote overseas operations. Despite all the logistical issues of using 80-ton tanks in such operations, it has been decided that having a number of spearhead armor divisions equipped with high-end tanks is no longer a luxury. With the development of an advanced in-house tank yet in an early stage, it has been a nearly unanimous decision that MCA-7E is the best option for filling that role, at least for the time being.

Therefore, we are requesting procurement of the following materiel:
- 12,800 MCA-7E main battle tanks;
- 14,400 PIV-30 infantry combat vehicles;
- 2,400 TD-7 self-propelled guns;
- 800 ADTV-7 air defence vehicles;
- 800 TLB-18 mobile bridges;
- 800 vehicles on a fully armored chassis, modified for a command and control role.
Concerning the last request, I understand that such a vehicle is not offered, but we are sure it can be created. Of course, due to the nature of their role, no electronics associated with command and control operations are required; we will install our own systems. A requirement is, however, that such a vehicle is not easily visually identifiable as a priority target. We would like to know if you would recommend to use the PIV-30 chassis for the role, or a different option.

I should also note that our technical team has been somewhat puzzled by the installation of a 2800 bhp engine in the TLB-18 Tank Launched Bridge. At 84.3t, it has a higher power-to-weight ratio than even the MCA-7E tank, while from our experience with previous-generation tanks, it has been our understanding that already at 20hp/t the only obstacle to a 85km/h speed is rapid tracks wear, rather than engine power.
Seeing as excess engine power tends to lead to higher fuel consumption, and a mobile bridge is not the kind of vehicle that needs the most rapid acceleration, we would be interested in your opinions on the practicality of a variant with the same 2000 hp Guarita DO66-2T00 engine as used on the PIV-30 IFV, for the sake of improved logistics and fuel economy.


In the longer term, while the prospect of an advanced in-house chassis is far beyond the horizon, our company's Engineering Department has offered to start a number of projects using the MCA-7 chassis, starting from a missile launch system, up to an intermediate chassis and a testbed for domestic tank development. So, we would would like to inquire as to what the cost of the MCA-7 chassis would be, with full protection and equipped with the 2800hp Guarita engine, but without the turret or any offensive systems.
Domestic production rights are not sought; we trust your company to produce these chassis more cost-effectively and with a more consistent quality than we would.

With best regards,
Farrell Norton,
Aerospace Logistics Corporation,
Nonconsensual Delivery Department,
XW 01A Commander.

[ooc:
I understand it's not the general policy, but a more detailed reply than 'confirmed' would be helpful. I'm not specifying the total price as it will have to adjust with the different engine for the TLB, specified price for the C&C variant/chassis, or with the addition of raw chassis purchases.

Also, could you look into this thread when you get some time? http://z3.invisionfree.invalid.com/HighTech/ind ... wtopic=130
I'm gradually actually starting to work on the tank, and there are a few crucial questions I really need your input on. ]

[Dostanuot Loj]

To Aerospace Logistics Corp.

Mr. Norton,

First and foremost we appreciate your interest in our products for your heavy armoured units, it is a choice not likely to fail you in the future. That said, I will address your issues. All your purchases specified are confirmed, of course.

To address your command vehicle concerns, the Sumerian Armed Forces developed a variant of the PIV-28 APC for such that role, externally identical to the regular PIV-28. As the PIV-30 is effectively an upgraded PIV-30, the transition should not be an issue. In fact, removal of the interior elements, keeping the gun, would allow for a map table, radios, and comfortable seating for 3-4 easily.

As to your second concern, the TLB-18 is, essentially, an MCA-7E chassis with the turret removed. The engine is a hold over for that reason. The engine, of course, due to the power transmission issues of the hydraulic transmission, does not use all of its power for mobility, and as such it does not fit well within the conventional power/weight theory, such things in application through the transmission are adjustable. A smaller engine is easily doable within the modular power pack element of the MCA-7 chassis. Both power packs, however, are extremely fuel efficient due to the nature of their transmission, allowing optimal RPM running at all times without changes in RPM which increase fuel consumption.

As to your final request, the chassis itself as a single entity can be sold for $5 million USD if desired. They would, in effect, be surplus Erimkalam MCA-7G hulls and should thus be perfect candidates for conceptual work. New hulls may be an issue though, as MCA-7G production is winding down for the future replacement tank project.

Let me know if there is anything else I can do to help you.
