High Quality Content by WIKIPEDIA articles! The United States Marine Corps (USMC) is a desegregated force, made up of troops of all races working and fighting alongside each other. In 1776 and 1777, a dozen Black American Marines served in the American Revolutionary War, but from 1798 to 1942, the USMC followed a racially discriminatory policy of denying African Americans the opportunity to serve as Marines. For more than 140 years, the Marines recruited primarily European Americans and white Hispanics, along with a few Asian Americans.
