Previously selected for the United States Special Operations Command in 2008, in March 2012 the United States Army ordered the Puma All Environment (AE) and designated it the RQ-20A.[2] In April, the United States Marine Corps and United States Air Force placed a similar order for the RQ-20A.[3][4] Each military RQ-20A system has three air vehicles and two ground stations.[2] The Puma AE can operate under extreme weather conditions including temperatures ranging from −20 to 120 °F (−29 to 49 °C), wind speeds up to 25 knots (29 mph; 46 km/h), and an inch of rain per hour.[5]
