Depends on the map, and at what bases you're fighting at.
Some have very short average range of engagment, while others have very long averages.
But if you're moving, you're going to have a much harder time hitting your enemy than he will have hitting you. He just has to lead. You have to deal with the bouncing of the tank, giving negative lead, and making sure you don't hit a tree and flip. That likely means that if there is a shot, the enemy isn't going to be the one burning.
