The 366th Infantry Regiment was an all Colored (segregated) unit of the United States Army that served in both World War I and World War II.^[1] In the latter war, the unit was exceptional for having all black officers as well as troops. The U.S. military did not desegregate until after World War II.^[2] During the war, for most of the segregated units, all field grade (majors and above) and most of the company grade officers (second lieutenants, first lieutenants, and captains) were white.
