The 93rd Infantry Division was a "colored" segregated unit of the United States Army in World War I and World War II. However, in World War I only its four infantry regiments, two brigade headquarters, and a provisional division headquarters were organized, and the divisional and brigade headquarters were demobilized in May 1918. Its regiments fought primarily under French command in that war. During tough combat in France, they soon acquired from the French the nickname "Blue Helmets" (), as these units were issued blue French Adrian helmets. This referred to the service of several of its units with the French Army during the Second Battle of the Marne. Consequently, its shoulder patch became a blue French helmet, to commemorate its service with the French Army during the Spring Offensive.
