African-American Marines at Montford Point were initially trained by white drill instructors. Five exceptional recruits, Mortimer A. Cox, Arnold R. Bostick, Edgar R. Davis, Jr., Gilbert H. Johnson and Edgar R. Huff, were singled out for their leadership and maturity to become the first African-American Drill Instructors. In honor of their legacy as the first African-Americans to mint Marines, Montford Point was renamed after one of them: Sergeant Major Gilbert H. "Hashmark" Johnson on April 19, 1974. Known as "Hashmark" because he had more service stripes than rank stripes, Johnson was not only a distinguished Montford Point Drill Instructor, he was a Veteran of WWII and Korea. In WWII, Johnson, a member of the 52nd Defense Battalion, asked that African-American Marines, who were exempt from combat patrols, be assigned to the front lines. Once approved, he personally led 25 combat patrols. Camp Gilbert H. Johnson is now home to the Marine Corps Combat Service Support Schools.
