Answer:
Banned discrimination in the armed services.
Step-by-step explanation:
African-Americans experienced some amount of improvement in civil rights thanks to President Truman. He desegregated the military and the federal government with Executive Orders 9980 and 9981.
Executive Order 9980 began by saying, "The principles on which our Government is based require a policy of fair employment throughout the Federal establishment, without discrimination because of race, color, religion, or national origin."
Executive Order 9981 stated: "There shall be equality of treatment and opportunity for all persons in the armed forces without regard to race, color, religion, or national origin."
