The U.S. Army confirmed in February that electromagnetic pulse (EMP) grenades, a favorite weapon of science fiction authors and video game creators, are in development. According to Colonel Laurie Buckhout, chief of the branch's electronic warfare division, the device will enable foot soldiers to instantly shut down all computers and other electronics within a large area, like a building or a small village, without harming people.
