A 50 cal heavy machine gun with auto laser aiming mechanism. Thats a scary thought. Mounted in the back of a plckup truck that is one hell of a mobile weapon I hope I never run into on the wrong end.
Rat Patrol on steroids!
Extremely short wave radar to track the target, A computer to take in all the variables and several servos to aim.
Radar on a quad would be really, really cool!
