It isn't really any of that, since "generations" only refers to MBTs in the same way that current fighter generations don't include P-51 or the Sopwith Camel but start with the jet age.

You can just go and look up a list of tanks and their generation, although it's worth noting that unlike fighter generations, tank generations aren't nearly as widely used nor are they quite as clearly defined. Current generation tanks are generally defined by their use of bulging plate armor, a higher caliber main gun (120-125 mm), integrated passive thermal sights, the end of the tradeoff between speed and armor (AMX 30 vs. Chieftain), etc. Not every single modern tank has these traits, but they will have most of them.

The problem is that aside from a crew in hull arrangement nothing that Armata does is new. The Russians already had APS. They already had add-on "stealth" plating (which they didn't bother to use). And even the crew in hull arrangement isn't really new, the Russians are just the first ones to think about putting it into production.

It gets even odder when Roski tries to compare it to K2 Black Panther as "another" fourth generation tank (which no one IRL is claiming) because K2 doesn't have a crew in hull arrangement so there is literally no feature or set of features that can be used to define the new generation.

the tank has data-link communication

And? It isn't a new capability.

[Kassaran]

K2 is bae. I love it and I think it is the best tank built. Fite me.

No, but seriously, from the whole list of goodiees it has built-in, it seems like it really is the top-tier MBT in production right now, the only things keeping it from being mass produced is the relatively late introduction of the tank and that it has been specifically engineered to fight one country, China North Korea.

It has worse protection than a number of existing tanks.

This is hardly surprising given how light it is. The switch to an autoloader is not enough to overcome this. It is the same with Type 10.

[Deutschess Kaiserreich]

Can these types of troops be possible? Linking from my factbook

Here it is:

The 72nd cavalry "Death Korps" division

The 72nd cavalry "Death Korps" are among the most mobile forces in the Imperial Army. They have the ability to cross dozens of kilometers in a day. They are among the best for hit and run, Recon, and Reinforcement of units. They are also the best infiltrators in the army and are known to be able to fight behind enemy lines for extended periods and cause havoc. They received their name "Death Korps" during the third Weltkreig and under the command of the current Kaiserin of Germany. Every year ten "Death Korps" are chosen to be in the Imperial guard. While the Kaiserin no longer commands the "Death Korps" but they have pledged their loyalty to her. During the third weltkreig and shortly before the Battle of Kursk began they their unit ambushed Soviet General Lytkin Yefim personal transport convoy and killed him crippling the command structure of the Kursk salient defenses. On their Return to the front lines, they participated in the Second Battle of Kursk were during the battle the 72nd cavalry division attacked the scattered remains of the 23rd Soviet heavy tank battalion and prevented them from merging with the 41st Soviet Light tank brigade. However, these engagements would cost the division dearly and they suffered 46% casualties. The Division was withdrawn to Berlin to remain as a Reserve unit. When they built up their numbers once more they were Just before the Third Weltkreig ended the "Death Korps" received new members and set out to the Chinese front. The "Death Korps" ambushed and chased down retreating Chinese divisions and in the Battle Khalkhin Gol, her division scattered multiple infantry battalions. During the battle, the "Death Korps" smashed a marshaling area that was preparing for a counter attack. Chinese casualties were extremely high in that attack and were recorded to be over 7,000 dead with the "Death Korps" only suffering about a hundred dead. THey returned with celebrations to Berlin

The 5th motorized stormtrooper division



The 5th motorized stormtrooper division is one of the most famous military units in the Kaiserriech. So much so that they are normally referred to as the "5th division". They are the best of the best of the stormtrooper corps and are capable of anything. Be it storming a fortress with only one squad or taking on a whole army and holding them back for entire days (Those two things have actually happened). They are the best at storming prepared positions and strike fear into any force they come across. They are hand selected and train for two years until they go through trials to be considered a basic infantryman. Those that fail the trials are usually taken in by less elite units but are still considered elite. The average soldier is capable of advanced infantry tactics, they have the skills of Junoir officer, and are trained in the basics of operation an armored vehicle. They are also fanatical to the crown and are willing to die at a moments notice for the Kaiserreich. Pray to your god if you hear the 5th division is the area.

The 51th Rear Echelon Gaurd Brigade

The 51st Rear Echelon Division maintains order in occupied territory. They are trained to combat counterinsurgency operations and defensive position building. They suppress a rebellion in occupied territory yet they are not ruthless. The average member of the Brigade is trained to be highly compassionate and charismatic. They are also highly skilled builders and often build magnificent positions that can hold entire armies back. They were responsible for preventing the entire annihilation of the 5th Army group during Operation Case Blue in the third Weltkreig. They protected the Army's rear as they retreated and halted the 7th Soviet Amry Group for several weeks in the City of Volgograd. The fighting in the city was fierce with the western half of the city nearly utterly destroyed. Eventually, the Brigade was forced over the Volga but not before they had inflicted serious casualties on the 7th Amry. They are extremely popular in their occupied territory as they are often seen to be distributing aid to the Local citizens. There is saying in the Brigade to goes "Wolgograd brach vor der Wache" which translated means "Volgograd broke before the guard did.".

The 7th "Steel Division" Panzer Division

The 7th "Steel Division" Panzer is fearsome of the Kaiserriech's armored force's. They can pierce any defensive line and move many miles in simply hours. The can overrun any defensive line and crush any army that stands in their way. Their Firepower and skill trumps all divisions they come across. Their tank crews are the best in the Kaiserriech and their kill count often numbers in the dozen. The famous tank commander Woldemar Wittman and Hartmut Himmler come from this Division and their kill counts number in the hundreds. They were born in the fire during the fall of Mittleafrica to the South Africa People Union during the second Weltkreig. For days they fought through the hardiest of Enemy armor and destroyed vast amounts of tanks crippling the SAPU tank arm. They encircled the last army of the French in France and had the honor of marching into Madrid. They are currently under the command of Mark Rommel.

In theory, yes. Though why you would want horse cavalry in an era with Leopard 2s is beyond me.

It's actually designed to fight North Koreans, though. Koreans are not naturally democratic (very likely they have the highest number of coups and strongman dictatorships of any single nation since the end of WW2 and possibly since the time of Christ; their last president was controlled by a Rasputinesque character) and their alliance with America is convenience. They abscond to whoever appears strongest/best positioned regionally, which is either Japan or China historically, depending on who is winning at that moment in time. As soon as the threat from DPRK disappears they will have little need (and desire) to associate with the United States and will defect to the PRC and their vassal Russia, as a sort of cyber age Goryeo/Joseon is the natural state of a unified Korea. It has a bigger chance of being used to kill Americans than it does to kill North Koreans, though, albeit both are small.

USA and Japan have a fairly strong alliance (the biggest danger to Japan is America stops seeing them as useful) but Korea is essentially a egg timer that swaps sides when Kim the Younger dies without an heir or whatever causes the North to implode. Better to have a land border with PRC/Russia and accept tacit vassalization (a known quantity) than to have the Americans run an undefended convoy of merchant ships every few months to provide you with sufficient energy to keep your lights on.

Is there any merit to AA systems being used in modern military forces today? I saw this being tested, back in 2017. 57mm caliber, crew protection to a limited degree, automated and computational systems, no towed vehicles. Surely a decent option for limited forces? And the 57mm is better than the 30mm dual SPAAG/SAM variants at least.

Yes, AAA is still effective against aircraft flying low enough. Generally speaking, if they're below 10,000 feet you can practically engage them with AAA with a reasonable chance of actually hitting them. This notably includes the altitudes that helicopters are usually operating at - attack helicopters are not very survivable in the contemporary speculative high-intensity tactical climate if caught in the open within two or three miles of an SPAAG.

The catch is that SPAAGs can't do very much to counter a high-flying aircraft, but that traditionally was solved by having medium and high-altitude SAMs. Stealth aircraft break this tactical arrangement by flying high and denying the enemy tracking information. Electronic warfare can also do this by denying targeting information - in aerial warfare, it doesn't matter if you know where the enemy is if you don't know precisely enough to hit him with a weapon. There is no such thing as suppressing fire against combat aircraft, so any shot fired without a decent chance of hitting something is a waste of ammunition.

In short, they're still useful against low-flying aircraft and guided weapons. As such, it's a good idea to keep them around to prevent that approach from being exploited by an enemy force in time of war.

EDIT: A bit late to the party on this one, but I felt the need to chime in:

considering literally only the *Zumwalt*-class destroyer and the F-35 really have those capabilities irl, ok

Data links are old technology. What's new about them is that the computers connected to them are much more advanced, which enables a lot of old concepts that used to work in isolation to be incorporated into one big network of lethality. A Littoral Combat Ship can fire a SAM and hand it off to an E-2D Hawkeye for mid-course updates and terminal guidance. An F-35 can fly along the 38th Parallel in Korea and passively detect and identify aircraft sitting cold on the tarmac and in open hangers facing south 20+ miles away, turn that into GPS coordinates, and send that in real-time to a flight of F-16s looking for targets. The data can go over satellites down to Nevada, San Diego, Washington DC, or anywhere else with a command center interested or drone pilots flying aircraft from 10 timezones away. The difference is the number of nodes available now, and the hardware switches to cope with cyber and electronic warfare degrading the system.

• It is not necessarily better. Discounting guided weapons technology supplies us with two different flavours of AAA: High ROF, low caliber (about 1 inch) weapons which rely on a direct hit and low ROF high caliber (about 2 inches) shells that rely on sophisticated proximity fuses. The former is proven effective against all targets, from aircraft to micro-UAVs and mortar bombs, at all altitudes but it is limited by its short range. The latter promises more range and higher ceiling but the sophisticated fuses needed to ensure consistent performance at low altitude and against small targets are comparatively unproven technology. The gun you linked if one of the latter, and development of the required proximity fuses has been part of its development. But it has yet to see any action. The twin gast guns used by the Tunguska and Pantsyr are short range but they are all but assured to work, limited only by the performance of their fire control systems.
• AAA is consistently one of the most lethal air defense systems. Though aircraft can and do avoid AAA entirely quite often by flying above its reach, when they do have to fly into its envelope it is extremely effective.
• Even with the decline of low altitude flight tactics which consistently brought aircraft into AAA range, AAA has found new life shooting down munitions and small UAVs. As recently as the 80s it was considered impractical to directly engage something like a rocket or bomb with mobile AAA, but the great advances in electronics have made this a routine occurrence. This has however made accuracy and fuse performance even more demanding, these targets are quite small physically and can move quite slowly. This has put a squeeze on calibers between about 1 and 2 inches (notably the historically popular 35mm and 40mm) as they are generally excessively large to be used as very high ROF weapons, but fire shells which are still somewhat small for packing super-accurate proximity fuses - while also providing the impetus for dusting off the old 57 mm guns that fell out of favour in the 60s.

Off topic a bit, but do you have a source on the larger guns coming back specifically because of the fuses? I could totally use that for an academic paper I'm writing on CIWS.

1. The idea there being that the medium mortar platoon can dismount with the 82mm, whereas the 120mm is wheeled. It's got better and more powerful ordnance but I wanted the option of something that could support on foot in very built-up areas, forests or mountains.
[/quote]

Okay, a couple of options.

Dual arm your heavy mortars with medium mortars. Stryker units do it an don't seem to have any major issues. or Add a medium mortar paltoon to the heavy mortar battery.

The problem with dismounted mortars is keeping them in business. They can burn through ammo very quickly, much more then a dismount crew can carry.

Your medium mortars might be a candidate for a light 4x4. That way they can be air assaulted if the battalion were to do such a thing

Some highlighted feature :
1.15-20 Km kinematic performance against most air threats from 5 meter to up to 18000 m
2.150 Km range S-band battle management radar, tied to command post
3. All battery component can be towed by typical 4x4 tactical vehicle and can be airlifted with helicopter

pretty much NASAMS eh at this point.

I'll consider it. My plan has always been to use real world vehicles because they have qualified stats, I'm not sure there is the chance of doing what you say with real world Russian/Chinese/Indian weaponry which I try and stick to. With the 2K32 system, it carries around 84 mortars of all kinds (with at least 40 of the 3VO36 rounds). Dismounted crew couldn't carry that, I say if they are burning through that much more ammo it's because they know they have it to expend, are dismounted teams keeping one eye on expenditure and so it looks like they don't burn through their ammo stock as quick? I wonder.

Your medium mortars might be a candidate for a light 4x4. That way they can be air assaulted if the battalion were to do such a thing

The same company that produces the 2K32 system also produces this light 4x4 buggy system.

They're in their own organic unit. a Battalion to be more exact.

I haven't i'd give the system a tracked chassis when im not lazy.

I have a dilemma that has been in my mind for a while:

Using slightly-postmodern military technology (2040s to 2070s), what would it take for one country to forever render Earth uninhabitable for even the blue tits, or send the planet into a death orbit with the sun? I have a feeling that using all nuclear weapons may not be enough to send Earth into death orbit with the sun.

I am asking this, because if it isn't possible, then obviously it makes no sense for anyone in my roleplay to make such a claim without being mocked.

To make earth uninhabitable to that level would require FAR more nuclear weapons than have ever existed. Considering the K-T asteroid that contributed to the extinction of the Dinosaurs delivered 100 million MT of TNT equivalent energy, several orders of magnitude beyond what humanity has produced, and failed to completely render earth uninhabitable to life in general (of course saurids and their relatives would say otherwise)...

National-to-regional societal collapses of areas impacted by atomics as well as good ole fashioned famine and other second-order effects are more plausible.

Whoever is claiming that for 2050-2070 is probably high.
