I have terrible problems with GVs. I've been in a T-34 and shot Panzers from point blank range at all angles with AP and HE and not killed them. I've killed ONE Tiger in a T-34, it was a one shot kill, from the right front, an AP round hit where the turret sits on the body. It exploded and disappeared. I've hit Panzers and Tigers there before, from the same range, and done zero apparent damage. Just last night, I was trying to shoot a T-34 from behind a group of trees, with my barrel appearing to stick through the trees. I could not shoot out of the trees. But the T-34 hit me once through the trees, and killed my Panzer. I make no claims as to what is right and what is wrong, the only claim I make is I don't understand what happens, and why, at all. I've had an M-16 literally kill a T-34. It took out the turret from behind before I could move or turn to shoot back.
