A metal and enamel device 1 1/16 inches (2.70 cm) in height overall consisting of a shield blazoned as follows: Azure, on a pale Or the shoulder sleeve insignia of the 32d Division Proper (a Red arrow having shot through a line), on a chief of the second three fountains. Attached above on a wreath of the colors Or and Azure, a badger couchant Proper. Attached below and to the sides a Gold scroll inscribed "LES TERRIBLES" in Blue letters.
The shield is blue for Infantry. The pale, dividing the shield into thirds, alludes to three of the major offensive engagements in which the organization as an element of the 32d Division participated in World War I. The red arrow is the design of the shoulder sleeve insignia of the 32d Division. Traditionally, the word "Wisconsin" means "wild rushing waters," thus the three fountains, heraldic symbols for water, appropriately stand for the Wisconsin Army National Guard regiments: First, Second and Third, from which elements stemmed to make up the organization during World War I. The motto translates to "The Terrible Ones."
The distinctive unit insignia was approved on 15 March 1926. It was amended to revise the description on 20 April 1926.
