The SMJ (Schweres Maschinengewehr Johnathan or Heavy Machine Gun Johnathan in english) Heavy Machine Gun is a Commoner designed 14.5×114mm caliber heavy machine gun based on the popular Soviet KPV heavy machine gun. The Soviets built the KPV during the the 1940's as a weapon to counter light vehicles (like armored personnel carriers, light vehicles, and light tanks), defeat defended positions like barriers or bunkers, and combat low flying aircraft like attack planes and helicopters. Commoners were very interested in the design and eventually re-engineered the KPV through a lucrative contract with Wolf Armaments. The SMJ was conceived during the 1950's as a lightweight anti-aircraft platform and vehicle primary armament. Due to its weight and cumbersome construction, plans to use the SMJ as an infantry weapon were nearly abandoned until decades later. Tests conducted by the design team lead by Leroy Johnathan (the weapon's namesake) proved the system's effectiveness as an anti-air weapon - later tests also showed the SMJ's effectiveness in penetrating light vehicle armor, giving Wolf Armaments confidence in the system's abilities as an anti-aircraft and vehicle armament. Once a produced product, the SMJ was first used on a small towed anti-aircraft weapons platform for mobile deployment; the SMJ-MAAG (Mounted Anti-Air Gun) as it was called was a one-to-four barreled 360 degree platform capable of light anti-air operations using turning wheels and standard iron sights. Armored vehicles were the next platform for the SMJ with a standard receiver able to operate on various armored vehicles; these recievers came with a multi-trigger configuration, allowing them to be manned using dual-handles with a trigger(s) system or using an electrical/mechanical trigger system. Aircraft and naval vessels soon saw their own versions being made promptly afterwards.
Modern models of the SMJ are based of its standard model, the SMJ-AP (Armored Platform) - a heavy jacket, shorter receiver version of its much older past version. SMJ-AP's are designed to be used on armored vehicles as their primary armament using an electrical trigger system - although the system could also be mounted on a remote controlled platform on a vehicle as well. Standard models for direct handling use a dual-handle trigger system for tightly controlled operation by the operator. These non-vehicle armament version are often mounted onto armored vehicles, mobile and stationary mounts, and can be rigged into stationary positions. SMJ's are closed bolt weapons that use a short recoil design with gas assistance to rotate the bolt. For enhanced performance, SMJ's use a mixed alloy for its barrel construction with a hard chrome bore for durability improvements. The air cooled barrel can be removed by turning a handle mounted forward of the receiver, allowing a crew to quickly exchange an overheated barrel with a fresh new barrel during combat. Standard engagement ranges for the SMJ are from three to four thousand meters, although bullets retain a lethal force at eight kilometers and can travel up to a ninth kilometer; a two thousand meter vertical height range is the SMJ's effective range against airborne targets. There are three models of the SMJ being produced by Wolf Armaments: the SMJ-AP used by vehicles and infantry forces, the SMJ-MP (Marine Platform) for naval platforms, and SMJ-ABP (Airborne Platform) used on aircraft mounts - the vastly produced MAAG variant has long since ended production, have been modernized, and were placed in storage until sold or needed by reservists. SMJ's play an important role in the TECT Armed Forces as its sole heavy machine gun system and heaviest infantry small arms weapon; its power and long engagement ranges have made the SMJ a favorite weapon system. The standard Commoner designed ammunition can be seen listed bellow as well as the descriptions of each version of the weapon.
AP14: The AP14 is an armor-piercing full metal jacket round with a tungsten-carbide (Tungsten-Cobalt alloy) core. It weighs about sixty-three grams and has a muzzle velocity of one-thousand and three meters per-second. Armor penetration at five-hundred meters is up to forty millimeters of rolled homogeneous armor (RHA) at zero degrees. Similar to the Soviet B-32 standard AP round - the AP14 differs by excluding the incendiary aspects for added performance capabilities, choosing to penetrate over any additional damage done by explosives or incendiaries possibly after penetration. AP14 rounds are intended to achieve better results against more well-protected hostile targets, such as tanks or fortified positions that have thicker armoring or depth to their construction material. A tracer variant of the AP14 allows for a two-thousand five-hundred meter burn.
AP14-B: An incendiary variant to the AP14 - the AP14-B offers an incendiary high explosive compartment that is off-timed to explode mere milliseconds on contact rather then directly on contact. This slight delay allows for the bullet to begin digging into a target before exploding - if the bullet fractures to the point of hitting the explosive compartment before the trigger receives the signal to detonate, the explosion will happen at that moment rather then later. Although usually unnoticed, this change in design can cause serious damage to armor by exploding while still penetrating the armor, causing major fracturing and bending to it. If the round penetrates fully without the explosion happening yet, it will directly explode inside the target as part of its intended result. The affect on ground is almost exactly the same as normal explosive tips, as well as heavier armor, which will often explode even faster as penetration is very little to minimal. AP14-B's weigh about sixty-three grams and have a muzzle velocity of nine-hundred and eighty-two meters per-second. Armor penetration at five-hundred meters is up to thirty-two millimeters of rolled homogeneous armor (RHA) at zero degrees. The tracer variant for the AP14-B can burn for two-thousand five-hundred meters.
HE14: The HE14 is a high-explosive full metal jacket incendiary bullet that uses an instant action detonation tip. The intention of the bullet is to explode on impact rather then to penetrate, causing shrapnel and force damage. Although not very capable of penetrating most hard armors - HE14 rounds can easily tear apart flesh, light skinned vehicles, and many aircraft build materials. The goal of this round is to explode upon impact, causing an explosion which sends shrapnel along with explosive force to anything nearby; a perfect example of this concept are proximity fuze rounds (although, these explode on proximity and contact) and artillery shells that explode on contact. For ground targets, HE14's blow apart people on direct hits or explode on surrounding surfaces, sending shrapnel and broken debris onto intended targets - they essentially maim their targets to death using shrapnel and explosive force in order to destroy targets, rather then an instant penetration of one projectile. Against aircraft they often penetrate just before exploding depending on the type of aircraft targeted; aircraft are especially at risk of HE14's as exploding incendiary shrapnel can be deadly as shrapnel could shred the air frame or kill pilots. HE14's weigh about fifty-nine grams and has a muzzle velocity of one-thousand and fourteen meters per-second. A tracer variant of allows for a two-thousand five-hundred meter burn.
SMJ-MAAG: The SMJ-MAAG is a mobile anti-air platform designed in the early 1950's. Since its original creation, the MAAG has seen a variety of enhancements that has modernized the system. An electric powered swivel unit speeds up the engagement of the unit; the electric motor also powers a tracking radar unit that guides the guns to fire on target and ahead of targets. The full use of electronics and motors means troops do not have to manually operate or sit on the platform anymore. Similar to other anti-air platforms operated by TECT, a 'Harpoon' FCS is installed on the unit to enhance the system's accuracy by leaps and bounds rather then using iron sights by default (a set of modern sight has been installed in case the electronics fail). The Harpoon FCS is an independent targeting & solution system that utilizes resources attached to it (a Ku Band radar unit in this case, or if other radar units are connected to the unit) to acquire targets and engage them with accurate "ahead" rounds. Although the system has these updates, the system can be operated manually by operators using simply controllers when set to manual. The platform is mounted on a four wheeled mount that is towed and locked down into place using breaks and locking pins. The SMJ-MAAG mounts up-to four barrels for use and can turn a full 360 degrees to engage targets; ammunition is stored on both sides for each set of guns in large box containers holding over four hundred rounds each. MAAG's can fire up to two-thousand eight-hundred rounds a minute onto target; mounts have varied from emplacements, warships, wheeled mounts, and vehicles. Although modernized, SMJ-MAAG's are not widely used due to being outgunned and having a shorter range then modern SPAAG systems that range from twenty to forty millimeter cannons.
SMJ-AP: The SMJ-AP is a vehicle borne variant of the SMJ; its infantry version is often used by infantry with tripods or other mounts where applicable (tripods or on vehicles, for example). Its version for vehicle use uses an electronic trigger system - it is well known for being used on the Puma Wheeled APC and the Bär Heavy APC as their primary or secondary weapons; on many vehicles it can also be a coaxial weapon or a top mounted weapon system. These armored vehicle systems use a connected belt feed line to storage unit that has one long belt rather then normal operating belts of fifty rounds; infantry operators will often use the standard fifty-round or hundred-round belt box of ammunition that attaches to the infantry version's receiver. This is a single barrel variant that can fire at six-to-seven hundred rounds a minute and be used on a variety of platforms.
SMJ-MP: The Marine Platform is a shorter length, short receiver, variant intended for use on naval ships like boats and warships. Used on small naval ships to larger vessels, it is designed to operate on dual or single mount turret units attached often to feed systems or use ammunition boxes. The Marine variant is popular on small fast moving patrol boats and larger naval vessels for its range and power against incoming targets; the often cool waterfront air helps keep the barrel cool from overheating. MP's have a one-thousand two-hundred and fifty millimeter barrel with a short receiver for decreased profile.
SMJ-ABP: The SMJ Airborne Platform is a modified variant of the original SMJ-AP designed for operation on aircraft. The primary differences between other SMJ-ABP and AP are its receiver build and barrel. ABP's barrel features a cover that's better for air cooling, is shorter in length down to one meter, and has a new barrel break that further relieves pressure on the receiver. Its receiver is modified so that it can mount from its roof and its bottom, is slightly shorter, and has a bolt that speeds up the firing action (firing speed is increased). The ABP fires about eight-hundred rounds a minute, features a one meter improved air cooling design, and can be mounted on vehicles or gunner points. ABP's are used on helicopters, attack planes, and other aircraft platforms.
Simunition Conversion
Conversion kits are available for all models of the SMJ HMG; they include a bolt carrier (partly colored blue to distinguish it), blank-firing adapter for firing blanks, and an upper receiver colored blue to distinguish it for its practice use. The standard kit will also include a laser transmitter for laser combat systems to use; such systems would include individual soldiers carrying small laser receivers scattered over their bodies, which detect when the soldier has been illuminated by a firearm's laser. Each laser transmitter would be set to mimic the effective range and potential damage of the weapon on which it is used. Depending on how complex the laser combat system is, trainers can retrieve immediate results and statistics compiled by the system; such examples include readings that give medics a digital readout to determine which first aid method to practice and probability readouts. Using the conversion kit, the SMJ HMG can seamlessly integrate into these laser combat systems.
