The United States Colored Troops (USCT) were regiments in the United States Army composed primarily of African-American (colored) soldiers, although members of other minority groups also served within the units. They were first recruited during the American Civil War, and by the end of the war in 1865, the 175 USCT regiments constituted about one-tenth of the manpower of the Union Army. About 20% of USCT soldiers died, a rate about 35% higher than that of white Union troops. Despite heavy casualties, many fought with distinction, 16 USCT soldiers receiving the Medal of Honor and numerous others receiving other honors.

The Regular Army of the United States succeeded the Continental Army as the country's permanent, professional land-based military force. Even in modern times the professional core of the United States Army continues to be called the Regular Army. From the time of the American Revolution until after the Spanish–American War, state militias and volunteer regiments organized by the states supported the smaller Regular Army of the United States. These volunteer regiments came to be called United States Volunteers (USV) in contrast to the Regular United States Army (USA). During the American Civil War, about 97 percent of the Union Army was United States Volunteers.
