Army tests drone-killing lasers as threat grows on the battlefield

As Islamic State-piloted commercial drones complicate the offensive in Mosul, sending Iraqi troops scattering as grenades and bomblets rain down, the Army has field tested vehicle-based lasers to combat the growing threat of enemy eyes in the sky. Infantry-carrying Stryker vehicles mounted with the Mobile High Energy Laser, a 5-kilowatt beam that scrambles the circuits of drones, took part in demonstrations at the Maneuver Fires Integration Experiment at Fort Sill in Oklahoma, a 10-day exercise that ended last week.
