The US has added EMP (Electromagnetic Pulse) and ADW (Agent-Defeat Weapons) missiles to its arsenal to counter foes armed with chemical or biological weapons.
The U.S. is researching and deploying several 'exotic weapons' such as high-powered microwave weapons and laser cannons to help the armed forces seize or neutralize the so-called weapons of mass destruction (WMD) with greater speed and security -- as well as with less damage to surrounding areas or people, and less danger of inadvertently spreading toxic materials.
