Buff and scarlet are the colors traditionally associated with Support units. The chevron denotes support. The following images symbolize the home state of the Battalion - the Morion helmet suggests the rich Spanish heritage of the area; the Zia sun is adapted from the New Mexico flag. The sword indicates military readiness and the Warrior spirit. The key signifies the Battalion's logistical responsibilities. The light blue base alludes to coastal waters and the unit's lineage to the 515th Coast Artillery. The sun represents the unit's wartime service in the Philippines.
