Shield
The shield is blue for Infantry. The charges on the canton represent the 11th Infantry from which this Regiment was formed in 1917. Its first combat service was in World War I in the Gerardmer Sector in Alsace, a short distance west of Colmar. The bend from the arms of Alsace has been charged with the 6th Division shoulder sleeve insignia to show that the Regiment was with that Division in France.
Crest
The regiment was formed from the 11th Infantry in 1917. Its first combat service was in World War I in the Gerardmer Section in Alsace, a short distance west of Colmar; therefore, a mace taken from the arms of Colmar has been used for the crest.
