Carl Gruenler, vice president of military and government operations for American Technology Corp., says that being within 100 yards (meters) of the device is extremely painful, but its use should be limited to 300 yards to be effectively used. He concedes that the device is powerful enough to cause permanent auditory damage, but that it is only meant to be used for a few seconds at a time.
The device, which weighs around only 45 pounds, is currently being tested in regions of Baghdad Baghdad. The device was originally intended to be used by American warships to warn incoming vessels of their arrival, but have become another piece of America's weapons intended to deter but not kill. A similar device is the Active Denial System, which uses a painful energy beam to discourage would-be attackers.
