Don't know if someone has suggested this, but I would like to be able to fire my weapon when i'm in a vehicle. It would be great to give cover fire from a small assault boat as you approach the shore, sit in the back of a pickup truck and spread death around you, or fire from a passengerseat of a helicopter. This would be useful to those vehicles that dont have a mounted gun. Your accuracy, trying to fire from a moving vehicle, would of course suffer. But it would be better than to have no cover fire at all when inside a vehicle. You shouldnt be forced to leave the vehicle, just to be able to return the fire.
