In the modern United States Air Force, the Enlisted Aircrew Badge is still issued to 1A0X1 (Inflight Refueling), 1A1X1 (Flight Engineer), 1A2X1 (Aircraft Loadmaster), 1A3X1 (Airborne Mission Systems Specialist), 1A4X1 (Airborne Operation Specialist), 1A6X1 (Flight Attendant), 1A7X1 (Aerial Gunner), 1A8X1 (Airborne Cryptologic Linguist), 1A8X2 (Airborne Intelligence, Surveillance & Reconnaissance (ISR) Operator), X4N0X1 (Aeromedical Evacuation Specialist). However, the Officer Aircrew Badge is less often awarded (usually to Airborne Surveillance Officers (ASO), Flight test engineers (FTE), and a few communications, weather, and intelligence officers, depending on assignment).[citation needed] Enlisted RPA (Remotely Piloted Aircraft) Sensor Operators (1U0, previously 1N1) were awarded their own aircrew wings in 2010.
