Shield
Orange and white are the colors of the Signal Corps. The rays in chief, suggested by the State flag of Arizona, allude to the battalion's home station, Fort Huachuca. The rays are thirteen in number in reference to the total campaign credits earned in two wars. The two red sectors refer to the battalion's Meritorious Unit Citations, and the black and white rays refer to the knowledge required for night and day signal operations. The tiger symbolizes Vietnam, site of the unit's first wartime service. The lightning bolt connotes electronic communications and speed of response. The crescent, outlined in the colors of the Kuwait flag, represents the Persian Gulf region, site of the unit's second wartime service.
Crest
The meteor streaking across the octagon symbolizes swiftness. Its brilliance and speed refer to early methods of conveying information by means of signal lights and stands for the battalion's mission of providing military communications. The eight sides of the insignia, for the eight directions of the compass, indicate that the unit can transmit information in all directions. The eight sides combined with the six points of the meteor also allude to the battalion's numerical designation.
The coat of arms was approved on 12 January 1995. The first design was rescinded and a new design authorized on 30 August 1995. The coat of arms was amended to correct the blazon of the shield on 7 December 2001.
