Military, but just barely: Cal Guard -- the Title 32 component of the California National Guard. As rear-echelon as it gets. Protecting California from being invaded by Oregon, Nevada or Arizona.
Went through OCS in 2013-14 at Camp SLO. Attached to the Center for Military History.
The closest I'll ever come to combat is having to walk from my apartment in downtown SF to the BART station (on my way to a drill) while wearing my ACU, and gutterpunks shouting "Nazi" and "baby-killer!" at me.
Always remember: TAHAFE.
