Shield
Buff is a color traditionally associated with the Quartermaster Corps and brick red with the Transportation Corps. The bendlets symbolizing pipelines, represent a continuous flow of supplies. They also refer to the dual mission of the former unit, supply and transport. The annulet, symbolic of a wheel, alludes to transportation. The Arawe shield, from a Pacific Island people, represents a service by the 25th Supply and Transport Battalion in the Pacific Theatre during World War II and the Korean Temple commemorates service in the Korean War.
Crest
The basic elements in the design represent the 25th Supply and Transport Battalion's service in World War II, the Korean War and Vietnam, with a total of twenty-six campaigns and eleven decorations. The scarlet bands on the rice refer to the six Meritorious Unit Commendations: One for the Pacific, World War II, with the bolo knives alluding to the Philippines and the Philippine Presidential Unit Citation; two for Korea with the taeguk denoting the two Republic of Korea Presidential Unit Citations; three for Vietnam with the sheaves referring to the two Republic of Vietnam Cross of Gallantry with palm awards.
The coat of arms was originally approved for the 25th Supply and Transport Battalion on 9 September 1963. It was amended to add a crest on 17 October 1973. The insignia was redesignated for the 25th Support Battalion with the symbolism revised on 29 March 1991.
