even though they were allowed to serve as soldiers what types of discrimination did african americans face in the union army

Here ya are

1. They were not allowed to serve as officers / They were not allowed to serve in units with white soldiers
2. Poor conditions were made worse in that most soldiers were young men under the age of 21
3. During the Civil War, the nations debt grew by a large amount
4. It won the sympathy of Europeans, making it less likely for them to support the confederacy
5. They offered protection to small inland towns in Florida

Good Luck :)
Don't get caught ;P
