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 and saw action during the Second Battle of the Marne. They acquired the nickname Blue Helmets from the French, as these units were issued horizon blue French Adrian helmets. Consequently, its shoulder patch became a blue French helmet, to commemorate its service with the French Army during the German spring offensive.
