It worked in Europe in WWII too.
The Sherman was a pretty average tank, although far better than the dross we were building until 1945, but there were thousands of them. I think I read somewhere they built 35,000 of them - but that might have been the T34.
The Tiger and Panther, both armed with the legendary 88mm gun, were much better but fortunately the Germans didn't have enough of them.
Edit: Wiki says just short of 50,000 Shermans and 84,000 T34s.
