Final answer:
African American military units in World War II were segregated and usually kept from combat roles, led by white officers, and initially paid less than white units. Notable exceptions include the Tuskegee Airmen and the 761st Tank Battalion, who served with distinction.
Step-by-step explanation:
During World War II, most African American military units were segregated and often relegated to non-combat roles. These units were typically led by white officers. Although there were some advances, such as the increase in the number of black officers and the formation of all-black fighter and bomber squadrons like the Tuskegee Airmen, the overall policy of segregation continued. The Tuskegee Airmen and units like the 761st Tank Battalion demonstrated exceptional skill and bravery in combat. It wasn't until after World War II that the U.S. military was officially integrated. Regarding pay, African American soldiers received lower wages than their white counterparts during the war, a practice that was eventually corrected after advocacy for equality.
