The statement that accurately describes the distinguished service of the buffalo soldiers is: Fourteen buffalo soldiers were given Medals of Honor for their bravery during the Indian Wars.
This is a well-documented fact, recognizing the contributions and sacrifices of buffalo soldiers in that historical context. The other statements either contain inaccuracies or are misleading. For example, buffalo soldiers generally did not receive higher pay than White soldiers, and Black officers were not typically in charge of buffalo soldier regiments during that time. The name "buffalo soldiers" was given to them by Native Americans, believed to be a reference to their toughness and hair, rather than an insult.
