People try to sit in the background and snipe mobile artillery. The key to spoting and killing snipers is to keep as much of your tank out of sight. If you pull back your tank around a corner but continue to take shots consider the possible locations the sniper might be nesting. If you still have a artillery tank pull back as far as you can to repair, pull back out and bombard every possible hiding spot as you move out into the open. Sniper rarely move when they have a sweet spot to snipe artillery. You can heal the vehicle but they can't heal themselves. Happy sniping mobile artillery!
