I am in a mission where my infantry are cleaning up but my Panzer III's kept getting destroyed by Russian t-34's. My veteran tank crews can't even seem to hit the T-34's. Whats going on? I'm in hulls down position within 1000 meters and whenever i use shoot & scoot the tanks are taken out pretty quickly. Other tanks firing from about 1300 meters are having the same amount of luck. Is like we are wholly inaccurate in every way. Any tips?
