The extended support mission of the battalion is symbolized by the interlacing chevrons. The torii gate and the indented partition line simulating coral formations, allude to Okinawa where the battalion was activated. The motto indicates the absolute determination of the battalion to give its all in accomplishing its mission.
The pentagonal fort symbolizes the battalion's five main mission elements: supply, maintenance, transportation, medical service and administration. The bayonet refers to the secondary mission requirement to fight as Infantry, the wings recall airborne qualifications and the Aviation branch. Blue (DOD blue) denotes defense and refers again to airborne capabilities. Gold signifies excellence.
The coat of arms was originally approved on 18 November 1964. It was amended to add a crest on 24 May 2005.
