US Army deploys heat-ray gun in Afghanistan

BBC : The US Army has transported to Afghanistan what it calls its Active Denial System, a truck-based weapon that focuses an intense, but nonlethal beam of microwaves onto enemy soldiers at distances of about 500 m. ADS is part of the Pentagon’s Joint Non-Lethal Weapons Program , which includes optical weapons that distract without blinding and acoustic weapons that focus intense sound to warn off attackers.
