Think about it-- if you were the dictator of some third world country about to be invaded by the world superpower, and you had the chance to use a sherman even if it stood barely any chance of survival, you you do anything you could to delay them.
But I do think that it is kind of funny that the soldiers even knew how to operate it, considering the technical manuals would be in english!!!
Eventually, we'll be invading some country 50 years from know, and we'll see them using M1's and think that its primitive and pathetic.
