Remember, there was no "parity" between Axis and Allied armored forces. I'm not talking about the men who served, just the machines they served in. As I said above, the problem is not the FF. It's the overwhelming pressence of them on the battlefield.
Axis Armoured Divisions were destoyed from the air. Although the Red Army did better, in combining armoured tactics, with overwhelming numbers, coupled with their airpower, then the western powers did. "Shermans were rolling coffins" on the western front and no match for even a regular field upgraded PanzerIV.
Seeing a Panzer on the field now is like spotting low lancs...
Mine, Mine, Mine ???
