A silver color metal and enamel device 1 3/16 inches (3.02cm) in width overall consisting of three orange lightning flashes conjoined in base and surmounting a silver wreath of laurel enclosed in base by an orange tripartite scroll, the sections folded over on each other and inscribed "HONOR DUTY CONSTANCY" in silver letters.
Orange and white (silver) are the branch colors of the Signal Corps. The lightning flashes symbolize speed and communications; joined together, they form a strong base and branching out from this central point they indicate versatility and scope. The wreath alludes to excellence of achievement and the highest values and efforts of a military unit, principles which are echoed by the unit's motto.
The distinctive unit insignia was approved on 6 Jun 1978.
