The shield is blue for Infantry. The wavy fess with its green oak trees signifies the Meuse River and the Argonne Forest; the fleur-de-lis represents service in France in World War I; the patriarchal cross botonny identifies the regiment with the 79th Division, the unit's former assignment.
The crest is that of the U.S. Army Reserve.
The coat of arms was originally approved for the 315th Regiment Infantry, Organized Reserves on 2 Jul 1925. It was amended to withdraw "Organized Reserves" from the designation and to delete the Organized Reserves' crest from the coat of arms for the 315th Infantry Regiment on 20 May 1959. On 19 Jun 1970 it was amended to reinstate the crest of the Army Reserve and revise the symbolism of the design. The coat of arms was redesignated for the 315th Regiment on 1 Jul 1999.
