Tank Bug Strategy
Me and my buddies have found a foolproof strategy to deal with tank bugs quickly and cleanly, and you really only need 1 rocket shot.
Take a recoiless rifle or the disposable AT rocket and shoot it IN THE LEG. After only a single leg shot, weapons fire to that leg will kill it in seconds from only a single player.
Alternatively, a second rocket shot to that leg will drop it right then and there.
