American soldiers should soon get drone support beyond just big, expensive machines flying well above the battlefield. The US Army has requested industry information on the feasibility of making tiny drones (Soldier Borne Sensors in official lingo) that would help infantry gather intelligence on a small scale, such as peeping over a hill or around a building. Its dream recon machine would weigh no more than a third of a pound, launch within one minute and fly for at least 15 minutes. Ideally, the drones would be in service as soon as 2018.
