I too only had a few years from Air Force Miltary service but then went on and retired from Civil Service giving me a total of 42 years of Militray service. When I retired I was issued a Military CAC card that allows me to use the FAMILY CAMP GROUNDS. I have used several of them on my RV trips... I was a E5 in the Air Force and a GS12 STEP 30 in the Civil Service hehe...
This also gave several other benifits associated with retired military service. I however always felt I was abusing my rights and would be the first one to give up my room or camp site if I knew it was going to bump an active Militray Service person...
When staying in BOQ areas I always informed the front desk to bump me if any military people showed up needing room space...
I probably was bumped three or four times over several years of doing this - always at a BOQ facility...
