The bar dancette also simulates three arrowheads, signifying participation by elements of the battalion in three World War II assault landings, while the three vertical divisions allude to participation in World War I and II and the Korean Conflict. The scarlet chevron at center refers to the Meritorious Unit Commendation, the fleur-de-lis to the French Croix de Guerre and the Taeguk to the Korean Presidential Unit Citation, unit decorations awarded to elements of the Battalion for service in World War II and Korea.
The distinctive unit insignia was approved on 29 February 1972.
