ShieldScarlet is used with gold for Artillery; the blue refers to the Infantry percentage of the unit which is descended from the old 8th Infantry. The broken horizontal line represents the 370th Infantry of the 93d Division which broke the Line. The black disc charged with the blue helmet is the shoulder sleeve insignia of the 93d Division. The gold fleurs-de-lis on the blue background are taken from the arms of the province of Ile-de-France where the Regiment served in World War I Oise-Aisne action. The two gold wavy bands stand for the unit’s two World War II honors for service in the Rhineland and Central Europe. The wavy line represents water and refers to the Rhine River.
