I hit a Sherman from about 20 ft exactly broadside with T34 HVAP when he didn't see me hiding in the trees. Did absolutely nothing. He just ignored me and drove off. Hit him repeatedly as he left. Nothing. So I guess "Ronson lighter- Lights First Time Every Time" refers to some other version of the Sherman.
So as a T34 driver, I have yet another tank of which I cannot scratch the paint.
