What was not a discrimination on African Americans in the union army?

In the Union Army, one aspect that did not constitute discrimination against African Americans was their recognition and acceptance as soldiers, particularly after the Emancipation Proclamation in 1863. African American troops, such as the United States Colored Troops (USCT), were officially allowed to enlist and serve in combat roles, showcasing their contributions to the war effort. While they faced challenges, including lower pay and racial prejudice, their enlistment represented a significant shift in the perception of African Americans' capabilities and rights during the Civil War.
