Awarded to any enlisted member of the U.S. Coast Guard who completes three consecutive years of "honorable and faithful service.” Such service implies that a standard enlistment was completed without any non-judicial punishments, disciplinary infractions, or court martial offenses. If a service member commits an offense, the three-year mark "resets" and a service member must perform an additional three years of discipline free service before the Good Conduct may be authorized. The Coast Guard Good Conduct Medal was designed in 1923 and originally used enlistment bars as attachments, in the same manner as the Marine Corps and Navy Good Conduct Medal. In 1966, the Coast Guard began using service stars to denote additional awards of the Good Conduct Medal.
