The Reserve UPT Selection Board is held every six months at HQ AFRC at Robins AFB, GA. Individual ANG units have their own boards--two commands, two procedures. The Reserve board considers the various unit packages against the number of UPT slots the command has coming up and selects the individuals. Unit commander recommendations count as does other factors--college record, flight experience, test scores, etc. A General Officer recommendation counts a lot, if your wing has a B/G.
