As we know, East Germany fielded multiple Soviet-made tanks during the Cold War such as the T-54, T-55, T-62, T-72 and the T-80; the last Soviet tank fielded by East Germany. It would be a great idea to extend on Soviet made tanks in the German tech tree to complement the T72. Here are my proposals for each vehicle in the German tech tree:
T54 - would most likely be the 1951 variant as T54’s were first fielded in the late 1950’s (BR 8.0) T55 - T-55A (8.3), T-55AMD (9.0), T-55-AM-1 (9.0) T62 - T-62 (8.7)
Any evidence of that, iirc East Germany never operated t80s, the soviets just stationed them there, but was operated by the soviets (It is literally on your source).
I usually use Wikipedia, but ignore the most of what’s on the page and start digging into the linked sources, you can do the same with AI, search something, ignore what it actually says and just look into the source material it is using (you will see the problem with what it actually tells you pretty quick, a lot of it’s vehicle sources are from the War Thunder store page, the wiki or here…).
I won’t pretend it always works, but you would be surprised how often you can find some really good links.
