I am Retired Military, As for as I know only Active Duty Military gets base housing. I retired in 81 from the Military, but continued to work for the government as a drone pilot (Civilian) until 99. I was not allowed base housing as a civilian or retired Military. Being retired Military though, I could and did use the base facilities ie, Exchange, Gas station, Commissary, and MWR. All of the bases (AF,Navy,Army,USMC) I've been on, this was the case. I hope this is helpful information.
Thanks
