PERITIA COGNITO (Skill and Knowledge).
Crimson and yellow are the colors of the Ordnance Corps, and the winged cannon ball indicates Airborne Ordnance. Both refer to the present unit's origin as the 782d Airborne Ordnance Battalion. The pheon, a crossbow arrowhead, symbolizes the assault landing in Normandy and the Rhineland, in which the 782d Maintenance Battalion, an ancestor of the present unit, participated during World War II.
The blue disk alludes to the islands of the Caribbean, Dominican Republic and Grenada and the unit's service there. The caravel recalls that Grenada was discovered by Columbus as were the surrounding islands. The points on the star honor the unit's five decorations and service in five wars. The palm wreath tied in red, is the color of valor recalling the Meritorious Unit Commendation. The two Southwest Asia campaigns are represented by the scimitars; gold is emblematic of honor and high achievement. The palm highlights the tropical nature of Vietnam and the Caribbean.
