The "Tuskegee Airmen" is important in U.S. history because they showed that African Americans could fight as well as white troops. Option D is correct.
The Tuskegee Airmen was a group of African-American military pilots, both fighter and bomber, who fought in World War II. They were the first African American soldiers to complete their courses and join the Army Air Force.
They formed the 332nd Fighter Group and the 477th Bombardment Group of the United States Army Air Forces.
