This is mostly true in my experience. LOTS of reserve Navy folks, and from actual Air Operations Center reserve units and many years removed from flying tours. Imagine that, AOC folks working in an AOC....
My unit would be one of those, we have had a steady stream of folks getting involuntarily MOB'd the last few years and if they have the AOC AQD/NOBC's they usually go to a job related to that. Figure that, using the system how it is supposed to be used.
My assumption is that there are suppose to be X number of folks from each service for the CAOC and the USAF and Navy have good sources for their billets, from what little that has been described here the Marines haven't quite got as good a handle on that yet.
