The joint base program is a miserable failure. The 502 ABW ("owners" of JBSA) couldn't occupy one of the many historical buildings on Ft Sam Houston when they needed a new home. No, they had to build a new $9.7 million 25,000-square-foot headquarters just to show those lowly Army types who's in charge!
And sorry, the Air Force still resides on their Air Force Bases, and the Army on their camps/forts/garrisons/whatever. There is no "joint" in "JBSA Lackland,"which is what the signs now say when you drive onto base.
Bottom line, "joint bases" are a fucking joke.
