Apparently JBLM is Fort Lewis and McChord Air Force Base. But everything is “joint” now. So you can have an Air Force officer running the Army base, or an Army officer running and Air Force base.
My bad Madigan was the name of the Medical Center at Fort Lewis..and McChord was the Air Force Base...used to do TDY and would stay at the BOQ at Fort Lewis..memory not what it used to be..
