Air Expeditionary Task Force "Chopped" units are referred to as forces. The top-level structure of these forces is the Air Expeditionary Task Force (AETF). The AETF is the Air Force presentation of forces to a CCDR for the employment of Air Power. Each CCDR is supported by a standing Component Numbered Air Force (C-NAF) to provide planning and execution of air forces in support of CCDR requirements. Each C-NAF consists of a Commander, Air Force Forces (COMAFFOR) and AFFOR/A-staff, and an Air Operations Center (AOC). As needed to support multiple Joint Force Commanders (JFC) in the CCMD's Area of Responsibility (AOR), the C-NAF may deploy Air Component Coordinate Elements (ACCE) to liaise with the JFC. If the Air Force possesses the preponderance of air forces in a JFC's area of operations, the COMAFFOR will also serve as the Joint Forces Air Component Commander (JFACC). Commander, Air Force Forces The Commander, Air Force Forces (COMAFFOR) is the senior USAF officer responsible for the employment of air power in support of JFC objectives. The COMAFFOR has a special staff and an A-Staff to ensure assigned or attached forces are properly organized, equipped, and trained to support the operational mission. Air Operations Center The Air Operations Center (AOC) is the JFACC's Command and Control (C2) center. Several AOCs have been established throughout the Air Force worldwide. These centers are responsible for planning and executing air power missions in support of JFC objectives. Air Expeditionary Wings/Groups/Squadrons The AETF generates air power to support CCMD objectives from Air Expeditionary Wings (AEW) or Air Expeditionary Groups (AEG). These units are responsible for receiving combat forces from Air Force MAJCOMs, preparing these forces for operational missions, launching and recovering these forces, and eventually returning forces to the MAJCOMs. Theater Air Control Systems control employment of forces during these missions. Personnel The classification of any USAF job for officers or enlisted airmen is the Air Force Specialty Code (AFSC). AFSCs range from officer specialties such as pilot, combat systems officer, special tactics, nuclear and missile operations, intelligence, cyberspace operations, judge advocate general (JAG), medical doctor, nurse or other fields, to various enlisted specialties. The latter range from flight combat operations such as loadmaster, to working in a dining facility to ensure that Airmen are properly fed. There are additional occupational fields such as computer specialties, mechanic specialties, enlisted aircrew, communication systems, cyberspace operations, avionics technicians, medical specialties, civil
