With the recent overhaul of airborne assault vehicles, players find that they cant take a step outside their base without a helicopters minigun pointed in their direction. We should have a RPG that locks onto a vehicle when you aim at it. It wouldn't be able to fire without a lock, but would deal lots of damage to make sure the vehicle and the player(s) gets destroyed. It would only be a one-time use weapon, to prevent vehicle-jumping.
