The color yellow refers to the unit's original assignment to the 30th Armored Division. The wavy bendlet denotes overseas duty and the two divisions of the shield are used to signify World Wars I and II. The four fleurs-de-lis allude to service in Europe where four awards were earned by elements of the organization during those wars. The lightning bolt is symbolic of speed and direct action, thus signifying efficiency of signal communications.
The coat of arms was originally approved on 18 May 1967. It was cancelled on 6 Dec 1973. On 18 Aug 1981, the coat of arms was reinstated, the symbolism revised to accurately reflect historic events and the description of the crest changed to correctly reflect the colors of the wreath.
