I was at Fort Meade, MD which is a joint installation but isn't advertised as one. All the intel folks from the different branches utilized the same Army housing, we all performed the same types of intel jobs at the NSA, and on base sports was a blast! My shop supervisor was Navy, but the Ops Floor Supervisor was Air Force and Army. Initially, I had an AF supervisor who did my EPR that wasn't even in my AFSC...lol.
Every office had a good mixture of Marines, AF, Navy, and Army personnel. Trying to figure out how the NSA made it work using only two buildings for us all to include civilians.
