Attached above from a wreath Or and Gules, an American bison statant Proper. Attached below and to the sides of the shield a Gold scroll inscribed "STAND FIRM" in Black letters.
The use of the shield of the coat of arms originally approved for the 115th Cavalry Regiment, differenced by a border, indicates the descent of the Battalion from that organization. The red shield and the five gold fleurs-de-lis are for Artillery service in France during World War I. The chief is blue for the Infantry service in the Philippines. The gold sun recalls both the service in the Far East and the shoulder sleeve insignia of the 41st Division. The parting line is yellow for the Cavalry assignment of the unit and is made embattled to represent the fighting record of the old organization.
The distinctive unit insignia was approved on 23 November 1954. It was rescinded on 31 July 1961.
