Shield
The colors orange and white are for the Signal Corps. The black area represents Africa, the dark continent. The fire arrow, an early signaling device, represents the mission and battle experience of the unit. The mountainous terrain of Italy, where the unit served during World War II, is represented by the jagged division of the lower part of the shield.
Crest
The flaming circlet of steel commemorates the unit's service in Southwest Asia. The steel underscores the strength and resolve of the U.S. Army troops and materiel in Saudi Arabia and Kuwait. The flames allude to a signal fire or beacon and denote zeal and action. The spears represent combat readiness and participation in two wars, World War II and Southwest Asia.
The coat of arms was originally approved on 31 Jan 1962. It was amended to add the crest on 11 Jan 1999.
