Don't give up too easily. I'll preface this by saying my information is dated, but when I rotated out of Bagram in Jan 2008, we were sure there would be at least a 3-day layover in Manas, with accompanying subzero temperatures etc. Rode the C-17 up from Bagram and went to the inprocessing brief, where there were specific instructions for "transient aircrew" to go through a separate process to get immigrated into the country. My compatriot and I went over there dressed in our DFDUs and weren't questioned at all, we just let them take our passports over to the civilian side for about 20 minutes and then proceeded on to billeting to get our private rooms. Much better than rooming with 100 of our closest Army friends, in my opinion. We were transients, and we were aircrew, right? No falsehoods required.
Since my fellow aircrew member was female, the billeting airman asked if we'd be needing any help at our alert time since the dorms were separated by sex, at which point I looked at my watch and thought for a second, then told him we'd take care of it. I'm glad he hadn't gotten to the portion of his CDCs that taught insignia and the various types of wings, or he might have realized that there's no aircraft, either stationed at Manas or otherwise, that is crewed solely by two navigators...
