I meant offensively...
Offensively, it's an ACK barge.
Years ago you could do this. You could spawn at your base and defend having a single player man all guns in the buff (or 6 players all manning guns in each of their buffs). On the attack, you could land at a deacked base and kill everything that spawned. This why it was changed, because it became "the" way to defend, or cap a field.
Odds are pretty good it isn't going to go back that way any time soon.
