Erich
the old Sage
I do not think so. True with overwhelming superiorirty in manpower/equipment the Wehrmacht could be almost indestructable in Poland, Holland, France and the first year in the Soviet Union. After 1942 the Soviets used more and more ground flak pieces many of them mobile with their Tank forces. This is proven in STG 2's log-books for one unit which harrassed Soviet MT and armor through the whole war.
