Marine Corps Good Conduct
Created on July 20, 1896, the Marine Corps Good Conduct Medal may be presented to any active member of the United States military who demonstrates three uninterrupted years of honorable behavior in service. Infractions or any disciplinary action cause the three-year clock to start over. Prior to 1945, the requisite term of service was four years. There is a Good Conduct Medal for the Navy (established in 1869), the Marine Corps (1896), the Coast Guard (1923), the Army (1941), and the Air Force (1963).
