How about a chain gun with Helmet Sighting System. Wherever you look, the gun points. Just press trigger to erase, and I do mean erase any threat you might encounter with your vehicle.
My definition of Gun Control--- A steady grip and hitting your target.
"In God we trust, all others are suspects."
"If I shoot all the ammo I am carrying, either I won't need any more, or more won't be of any help".
