Camp Foster
The battalion is currently the only "stand alone" artillery unit in 12th Marines; 2nd Battalion was deactivated following due to defense cut-backs and the relocation of 12th Marine Regiment from Camp Foster to Camp Hansen, both in Okinawa. 3rd Battalion maintains its headquarters at Camp Hansen and sources the Unit Deployment Program as the headquarters element for deployed artillery batteries drawn from across the Corps. 3/12's permanent firing batteries have been reassigned to other units: Battery K to 2nd Battalion 11th Marines, Battery L to 3rd Battalion 11th Marines, and Battery I to 1st Battalion 11th Marines.
