Not really true. The Americans had lots of 90mm tank destroyers and tanks by the end of the war. We also had large numbers of 88mm German vehicles at our disposal along with vast numbers of good 76mm guns platforms. We would have complete air superiority in days and their tanks and artillery would have been liquidated by air power. The Soviets were bad to mass their forces which didn’t have to worry about strategic bombers by 1945.
If Germany had air superiority in the East, the Soviets never would have made it past Poland before we had overrun all of Germany.
Did the Soviets have the proximity fuze by this stage of the war, I wonder?
Because that was one of the reasons we decimated the Germans.
I read that they thought we had invented semi-automatic artillery.
