Explanation
During World war 2 which started in the 19th century, African-American units were utilized by the Army to combat the Native Americans during the Wars. The most noted among this group were the Buffalo Soldiers. Many of these men were unofficially allowed to enlist in the Union Army The African-American men registered for the draft, and black women also volunteered in large numbers.
