True. And they had a LOT of crummy tanks, too, like the BT series, the T-26, and “land cruiser” T-35. But, in 1940, they already had the T-34, which would eventually take them to Berlin.
My Father had several pictures of the first Russian tank to enter Berlin. He took pictures in 1945 of the monument being constructed and a few after it was completed.
Daddy simply described it as a “Stalin tank”. When he was in a nursing home not too long before he died, I took a bunch of his WWII pics to let him look at. Daddy smiled at the Stalin tank and said it was blown up during the night. Daddy had Alzheimers so I wasn’t sure if his memory was right.
Anyway I looked up on the internet, the first Russian tank in Berlin and sure enough, there are now two T-34s. They are in the same place (Tiergarten Square) so apparently after the first one was blown up they simply found two other “first” tanks into Berlin.
