The types of discrimination that African Americans faced in the Union army included:
- They were not allowed to serve as officers.
- They were not paid the same as white soldiers until after the war ended.
- They were not allowed to serve in units with white soldiers.
While they were eventually permitted to serve in the army, these forms of discrimination reflect the broader social and racial inequalities of the time. Option 2 is not entirely accurate, as some African Americans did receive awards, though generally, they faced significant barriers in recognition compared to their white counterparts.
