- African American soldiers and a white commanding officer
Explanation:
The 54th Massachusetts Volunteer Infantry Regiment was an infantry regiment made up of African American men enlisted by white officers. The infantry regiment is a division of an army engaged in foot (foot soldiers) combat battle. During the American Civil War, the 54th Regiment served in the Union Army. After the First Kansas Colored Volunteer Infantry Regiment, it was the second African American regiment.
It was the "League of Nations" that was the international governmental organization that the United States declined to join after World War I, since most Americans thought this would entangle them in more European wars.
