Staff fills at COCOMS or other big HQs. Most or all staff plus-ups were justified as war-time requirements of one flavor or another. This probably applies to all COCOMS and major HQ's even if their AOR was not the desert.

The navy was always good about putting the right language on the orders, other services perhaps not. But the orders do NOT need to state they are exempt, they just have to qualify under the rules, which can typically be demonstrated by the funding and/or authority under which the recall was conducted (which may well be stated on the orders somewhere).

IP = instructor pilot.
