ShieldThe shield is blue for Infantry. The silver of the pale and chief indicates the 127th Infantry is numerically senior to the 128th Infantry in the 64th Infantry Brigade. The 127th Infantry was federally recognizes July 14, 1920, and the 128th Infantry April 16, 1921. Tradition is that the name Wisconsin means "wild rushing waters," therefore, the three fountains, heraldic symbols for water, are used to symbolize the three Wisconsin regiments - The First, Second and Third National Guard Regiments - which were combined and from which organizations were drawn to make up the 127th Infantry; they also signify that the unit has been called into Federal service three times - for the Spanish American War, Mexican Border duty and World War I, at the time the coat of arms was approved. The red arrow was the shoulder sleeve insignia of the 32d Division and the rainbow that of the 42d Division, during World War I. The motto "LES TERRIBLES" is the nom-de-guerre conferred upon the 127th Infantry during World War I.
CrestThe crest is that of the Wisconsin Army National Guard.
The coat of arms was approved on 17 June 1927.
