Communism stronk, Anglos too few in number to wage war.
T-10 is also of soviet development. Is improved Joseph Stalin Tank(IS). Basically it is an improved IS-3, but was giving the name T-10 because Stalin died and the government wanted to get rid of everything related to him. Also the tank was moved to secondary tank fleets because Soviet officers knew that heavy armor was outdated by the 70's. Also T-64 more stronk. T-72 week, T-62 was a beefed up T-55 that was dropped on it's head. Not that you care, but now you know.
