A gold color metal and enamel device 1 3/16 inches (3.02 cm) in width overall consisting of three yellow rays on a light blue background radiating from behind a gray silhouette representation of "The Alamo" charged with a white star on the upper center and surmounted at the base by two blue conjoined wings, each charged with a gold lightning flash and all beneath a red scroll, the ends terminating at the tops of the wings inscribed "CONTACT" in gold letters.
Blue is for the sky, the aviation element, and gold (yellow) is for zeal, wisdom and achievement. The wings with flashes symbolize the aviation mission of the organization and the three rays refer to achievement, power and combat readiness. The Alamo is symbolic of the determination to defend state and country and the star alludes to Texas, the unit's headquarters state. The scarlet color of the scroll refers to the Red River which is common to Texas and Oklahoma, from which states the unit receives its strength.
The distinctive unit insignia was originally approved for the 111th Aviation Group on 17 August 1972. It was redesignated for the 149th Aviation Battalion and its symbolism revised to reflect the location of elements of the organization in Texas and Oklahoma on 3 July 1979.NOTE: A coat of arms was never approved for this Battalion.
