A silver color metal and enamel device 1 1/16 inches (2.70 cm) in height overall, consisting of a demi-disc superimposed by three orange lightning bolts conjoined in base, the center bolt terminating in an arrowhead and either side bolt terminating in a demi-fleur-de-lis all superimposed at bottom by a black bipartite scroll inscribed "FACIEMUS FORTIUS" in silver.
Orange and white are colors traditionally associated with the Signal Corps. The fleurs-de-lis commemorates the two campaign honors awarded the Battalion for service in Europe during World War II. The conjoined lightning bolts refer to the unit's coordination and swift provision of radio and land line communication facilities; the lightning bolt with arrowhead alludes to the organization's readiness and aggressive action. The hemisphere represents the Battalion's widespread service.
The distinctive unit insignia was approved on 10 February 1967. It was amended to revise the description and symbolism on 22 September 1993.
