Honestly, I don't know the source, but this is true.  When we are performing missions for agencies, companies, individuals or whatever (anything outside the Air Force, Air National Guard and related subsidiaries), we are just considered a corporation.  Many pilots have been buying unofficial patches with the words "Aux On / Aux Off" (see the patch and examples here).  Basically, when we operate for the Air Force family, we are a U.S. Code Title 10 organization; when we operate outside of the Air Force, we are a U.S. Code Title 36 organization.  IIRC, this is a situation that's been on the books for a while, but only recently recognized by the community at large.   T • @ • C
