Buff and scarlet are the color traditionally used by Support organizations. Gold is emblematic of excellence and high achievement. The divided shield underscores the unit's air and ground maintenance support missions. The blue alludes to the sky and the division line suggests clouds. The chevron denotes support and forward movement reflecting the units' motto. The lightning bolts, crossed for strength and cooperation, represent swiftness. The colors red, white and blue, and the star are adapted from the Texas State flag, home of the battalion. The wrench symbolizes the vital role of maintenance and the unit's mission.
The crest is that of the Texas Army National Guard.
The coat of arms was approved on 9 Sep 1998.
