But as I say, Matt, that isn't tracking.
Also competitive BF4 - lol
Its exactly the same. Tanks don't just sit still, especially at long range. You often have to lead your target to get a critical hit exactly the same as you do with infantry combat. You can also use a heavy LMG to shoot infantry from long range. It has extreme bullet drop, so accurate tracking and prediction of bullet drop is essential. Its identical to tracking on foot.
By competitive i mean playing with reasonable players.
