I am currently TDY Enroute at Nellis. I'm half way through my stay(off base) and Nellis lodging gave me a Non-Availability letter, but only for my first part of the stay. Can they legally force me to move back on base? I've been told by an O-4 and O-5 they can't, but the A1C at the lovely reception desk says they can. I've searched the only reg I can find, AFI 34-246, Air Force Lodging Program, but I can't find anything one way or the other. Anyone have any advise?
