It can't be stressed enough - SHOT PLACEMENT! If you know where to place your round, any GV can be taken out with 1 shot. Even those annoying T34's can be taken out with 1 shot from a panzer. Many times when I use M4's, I get called a cheat or "ASP has GOD TANKS!"....yea I wish. Even though you think you have a perfect broad side shot, take your time and adjust for a possible deflection shot. Many times I just rush through trees or around town, come up to any enemy GV point blank, be first to fire and....plink - DEFLECTION.....very sad, hang head in shame and take my punishment - BOOM I'm in the tower. So remember shot placement in vital!
