Fast Goodbye
Capt. Katrina Schweiker maneuvers the antenna on test system 1 of the Active Denial System, a humvee mounted version at the Air Force Research Laboratory at Kirtland Air Force Base, N.M. ADS is a counter-personnel, non-lethal, directed-energy weapon. The ADS focuses beams of millimeter waves that induce the sensation of intolerable heat on an adversary's skin. When the enemy steps away, the skin returns to normal temperature. The enemy is repelled without permanent injury. (U.S. Air Force photo/Staff Sgt. Bennie J. Davis III)
