A series of policies were formerly issued by the U.S. military which entailed the separation of white and non-white American soldiers, prohibitions on the recruitment of people of color and restrictions of ethnic minorities to supporting roles. Since the American Revolutionary War, each branch of the United States Armed Forces implemented differing policies surrounding racial segregation. Racial discrimination in the U.S. military was officially opposed by Harry S. Truman's Executive Order 9981 in 1948. The goal was equality of treatment and opportunity. Jon Taylor says, "The wording of the Executive Order was vague because it neither mentioned segregation or integration." Racial segregation was ended in the mid-1950s.

Executive Order 9981 was an executive order issued on July 26, 1948, by President Harry S. Truman. It abolished discrimination "on the basis of race, color, religion or national origin" in the United States Armed Forces. The Order led to the re-integration of the services during the Korean War (1950–1953). It was a crucial event in the post-World War II civil rights movement and a major achievement of Truman's presidency. Executive Order 9981 was inspired, in part, by an attack on Isaac Woodard who was an American soldier and African-American World War II veteran. On February 12, 1946, hours after being honorably discharged from the United States Army, he was attacked while still in uniform by South Carolina police as he was taking a bus home. The attack left Woodard completely and permanently blind. President Harry S. Truman ordered a federal investigation.
