The Air Operations Center (AOC) is the senior element of the Theater Air Control System. In the event of hostilities, the Joint Force Commander assigns a Joint Forces Air Component Commander (JFACC) to lead the AOC weapon system. Quite often the Commander, Air Force Forces (COMAFFOR) is assigned the JFACC position for planning and executing theater-wide air and space forces. When there is more than one service working in the AOC it is called the Joint Air and Space Operations Center. In cases of Allied or Coalition (multinational) operations, the AOC is called a Combined Air and Space Operations Center.
