A silver color metal and enamel device 1 3/16 inches (2.86cm) in height overall consisting of a shield blazoned: Azure, a pair of tilting spears in saltire, Argent. Attached below the shield a silver scroll inscribed "FIRM TO MY TRUST" in blue letters.
Blue is the color for Infantry and indicates the unit's origin. The functions of the Regiment are allegorically symbolized by the crossed spears heraldically representing dexterity, nimbleness of wit and ability to pierce, they being weapons of the medieval times.
The distinctive unit insignia was originally approved on 21 Apr 1943, for the 154th Infantry Regiment. On 5 Nov 1975, it was rescinded. The insignia was reinstated and redesignated for the 154th Regiment on 29 Jul 1999.
