Oh make no mistake, as I understand it when healthy and fully operational they were almost unbeatable.
I stood next to a Mark VI Tiger I about a year ago, at a WWII weekend event. It made a fearsome impression, for sure. The driver started up the engine, and the only word to describe it that came to mind was a “roar”. You could “feel” that motor vibrating your chest.
There was also an M4 Sherman there, with the long barreled 76, the “Easy Eight” version (similar to the one in “Fury”).
