If OP's friend is done with or nearing his ADSO, it's just a paperwork drill to either do an inter-service transfer if staying AD, with various wickets to overcome (getting the AF to agree to it, getting a UPT slot, passing a FC1 physical, taking the AFOQT/TBAS). If going to the guard, it's pretty similar to going AD to ANG as far as getting out then swearing back in, but again all the UPT "rushing" and getting hired has to occur, FC1/AFOQT/TBAS need to be done, etc. Ideally, he'd get all the wickets out of the way, take his required tests/physicals while on AD, get conditionally "hired" by ANG/AFRES/USAF, then go AD to new position with no break in service. Also, if he has over 5 years commissioned time in service or will be 30 by the time he'd enter UPT, he'll have to have waivers as well.
