ACHIN, AFGHANISTAN - AUGUST 30: U.S. Army Sgt. Don Stolle launches a Raven surveillance drone into the air from the Afghan government district center on August 30, 2011 in Achin, Afghanistan. The military uses the small unmanned aerial vehicles (UAVs) to transmit live video back and watch for possible Taliban movements near U.S. forces on the ground. The craft, controled remotely like a model airplane, can fly for up to 1 1/2 hours and a distance of about 6 miles on its electronic motor before being brought back and relaunched with a fresh battery.
