Another German general upon seeing a T-34 for the first time said, “If the Russians figure out how to mass produce it, we are going to lose the war.”
Yes! The T-34 was a game-changer. The German Mark IV was not nearly as good. The T-34 was very effective in the German retreat from Moscow in late 1941 and early 1942, (until General Model rode to the rescue), as well as the mother-of-all-tank battles at Kursk in the summer of 1943.
