It’s an enduring shame that the country that practically invented the car, and the assembly line method of mass production sent it’s son’s to war in a tank that was , quite frankly, a piece of crap. I’ve known men who served in armored units in WW2 and they were in awe, and dread of German tanks. And disgusted by the Sherman.
Yes, plus helping (from materials to vehicles to education) the Soviets so much that they became an advancing army who got to Berlin first, and which kept multitudes of abandoned GIs after the war ended, and greatly infiltrated our government, resulting in continuing proxy wars, cold or hot.
The choice of the Sherman was likely partly due to logistics/ its shipping size and weight, but maybe we should have obtained a flood of T-34S in return for all the help given to the Soviets.
