Death From Above
Ultra rare0.0%ObjectiveOptionalAnywhere
Drop a bomb from a plane and destroy or disable 4 vehicles at once (Campaign only).
This is hard because there aren't many vehicles, and they despawn if you go too far away from them. The easiest way is likely to spawn a plane with bombs, fly it to a garage and land it. Find 4 vehicles and park them super close to the plane (don't stray far or they will despawn!!). Then get in the plane and drop a bomb while you're still on the ground.
