Service in the Philippines is indicated by the sea lion from the coat of arms of the Philippines. The cactus refers to Mexican Border Service in 1916. The fleur-de-lis symbolizes World War I service in France. The green and gold/yellow of the motto scroll are the colors traditionally associated with Armor.
The distinctive unit insignia was approved on 19 June 1989.
