I find this to be a great Idea. It would add a whole new dynamic to the game. So many static weapons get over looked because every pilot, tanker and sneaky infantry man knows where they are. With the ability to change the statics it would actually allow defenders to set up a defense.
@ Jimi, this whole game is based on one person representing a crew, think about all the tanks or arty pieces. Its one person, driving, loading, aiming, firing the cannon and machine gun.
