Explanation:
The best answer to describe what was different for African American soldiers in World War II compared to World War I is that they had greater opportunities for advancement. Although they still served in segregated units, there was progress in terms of representation and roles within the military. The number of black officers increased substantially, and despite most being placed in noncombat units, some achieved recognition, such as the Tuskegee Airmen and the 761st Tank Battalion. However, the military did not fully integrate until after the end of the war.
