Lancer Space Cannon
The Space Cannon is a fully automated, unmanned attack vehicle which operates on reflex power. This means that the Lancer is directed by an artificial intelligence that can actually search out its target, identify, and attack. If the target is beyond its strike range, it will wait until a programmed target comes within range.
The Space Cannon is fairly mobile, able to take evasive action and even plot rudimentary strategies. It was used extensively on the A.R.M.D. orbital defense stations.
