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 fess Tenné and vair, in chief a lion passant guardant Argent. Attached below the shield a triparted Silver scroll inscribed "FOR THE COMMANDER" in Black letters.

Symbolism
Orange and white are the colors traditionally associated with the Signal Corps. The lion is from the Arms of Normandy, location of the first campaign in which the battalion participated in World War II. The heraldic fur known as "vair," resembling blue and white bells, refers to signaling.

History
The distinctive unit insignia was approved on 10 February 1965. It was amended to revise the description and symbolism of the design on 17 June 1991.
