Led by Colonel Dean Sturgis, the C.A.D.S. are a small force of U.S. soldiers who wear the Computerized Attack/Defense Systems suits that make them as deadly as high-tech tanks.Their seven-foot high, 200 pound C.A.D.S. suits are equipped with machine guns, armor piercing shells and flame throwers--all operated by computerized voice commands. After a surprise first nuclear attack on the USA this new unit is the only line-of-defense against the Soviet invaders.
