The energy-blasting G.I. Joe future that we've all been waiting for is steadily getting closer. Not only is the US Army outfitting trucks with increasingly powerful laser systems, it is also looking to provide similar capabilities to its dismounted troops as well. Dubbed "Burke Pulser" attachments after their creator Army Armament Research electronics engineer James E. Burke, these devices utilize a piezoelectric generator and two protruding antennas to generate powerful bursts of electrical. The entire unit fits onto the end of the Army's M4 carbine just as a standard-issue flash suppressor does.
