American drones fired more ammunition last year than manned warplanes for the first time, according to new data analyzed by Reuters. The news comes three years after U.S. President Barack Obama said that a drawdown of U.S. military forces after 2014 would "reduce the need for unmanned strikes." The data shows just how much American forces have come to rely on the unmanned vehicles to carry out missions in the Middle East and abroad, even while human rights organizations and some foreign governments have raised concerns over what they call an unnecessary amount of civilian casualties. "In recent months it's definitely flowed more," Lieutenant Colonel Michael Navicky, who commands the Air Force's 62nd Expeditionary Reconnaissance Squadron, said. "We've seen increased weapons deployment in the past few months, and the demand is insatiable."
