NOTE: This document was generated by the AAF and was obtained from the National Archives and is provided merely as an historical reference. It is a snapshot-in-time of units and their locations at the time the list was compiled. It is not completely accurate as units were often in transition between the times the list was compiled and published.

Also note that some of the APOs are not necessarily the location of the unit but rather the APO used by the unit.
