Insignia Description
A Silver color metal and enamel device 1 1/8 inches (2.86 cm) in height overall, consisting of a shield blazoned: Per chevron reversed Tenné and Sable, issuant in base between two fountains a splice of three wires spread at fess point per chevron reversed and per pale throughout, in chief issuant from fess point to chief Argent. Attached below the shield a Silver scroll inscribed "SPIRIT SPEED STRENGTH" in Black letters.

Symbolism
Orange and white are colors traditionally associated with the Signal Corps. The two fountains (white and blue wavy discs) in base denote the unit's participation in two Pacific campaigns during World War II. The spliced wires suggest the Battalion's particular function of cable construction, and crossing the black into the bright orange signifies the light of information brought by communications. The two flashes are representative of signals.

History
A distinctive unit insignia was approved on 26 November 1941. That design was cancelled and a new design authorized on 20 October 1967. The insignia was amended to revise the description and symbolism on 8 June 1992.
