Gustav and RPG but you need to plant a tracer on the vehicle firstWhich weapons lock onto vehicles battlefield bc2?
It's called a tracer dart. If you've unlocked it it's under the pistols tier. It basically sticks to the vehicle for a good 30 seconds and allows you to use any missle launcher with it and it will act as a heat seeker. So the enemy is basically sticking you with the tracer dart.Which weapons lock onto vehicles battlefield bc2?
You have to nail a target (which can be any enemy person or vehicle) and hold a rocket launcher sight over the box until it gives you the distance to target. The rpg, Carl gustave and I think there is another all lock on. But one of the launchers aim by pointing the sight. Hope this helped.
Vehicles can be locked on by an RPG or a Gustav IF a tracer dart has hit the vehicle. for more info check this out:
