Taking down tanks, just as a thought, when shooting a tank head on...try aim for the con-caved part where the tank turret meets the body. it does a lot more damage. plus if you did not know, it takes two shots in the bum of a tank to kill it. They have limited the tanks firing sequence which mean you need to use your ammo sparingly, so what BF4 has done it made the tanks faster with the boost. So on a 1v1 with a tank, best is to charge ahead and take that one or two shots and get behind the tank for a kill cause the enemy tank should already be on 60HP.
