This one's a sore spot.
A couple days after the bad guy attacked the recruiters and the Navy-Marine reserve center in Chattanooga in 2015, the Marine reserves armed up their people at their reserve centers- basically they organized a QRF at each one, a squad-sized element with the small arms they had on hand in their armory. The Marines did that both at their standalone places and ones that they shared with other services (Navy, Guard, for example). Now, when the Navy and Marine reserves share a location/building/fenceline/etc. then the Navy is often the lead agency. The Navy Reserve balked at this and ordered us (the Navy reserve centers) to not let the Marines be armed onboard the property, and that the standing agreements with local law enforcement were still adequate for force protection. Obviously the FOGO discussion on that hot topic didn't reach a consensus so the Navy sorta tried to backdoor the Marines on it.
Way different mentality on the blue side than the green side.
