The 328th Infantry Regiment’s Distinctive Unit Insignia was designed after its recall to active duty for World War II. The Minuteman at its top recalls the regiment's status as a Reserve unit and symbolizes its readiness to be called up at a moment’s notice. The alligator recalls the 328th Infantry’s years between the world wars when the regiment's headquarters and subordinate companies were located in Florida. The three fleur-de-lis are symbols of the regiment’s most important World War I engagements in France -- its initial battles in Lorraine and the St. Mihiel and Meuse-Argonne offensives.
