The only thing the Sherman had going for it was the astounding numbers of them that were built and sent to the battlefield.
Germany simply could not match those numbers.
Shermans are kmocked too much. They were incredibly easy to fix on a battlefield (15 min to fix a broken tread, one hour to swap out a turret behind the lines. Later up gunned models could hold against anything but Tigers. Their somewhat smaller size made them better in cities.
And the fact we built the average Sherman in 4.5 hour from scratch?
