The last of the Reserve Good Conduct Medals to be authorized, the Army Reserve Components Achievement Medal (ARCAM), was established by the Secretary of the Army on 3 March 1971 and amended by DA General Orders 4, in 1974. The Army Reserve Components Achievement Medal is awarded for exemplary behavior, efficiency, and fidelity while serving as a member of an Army National Guard or Army Reserve Troop Program Unit for each three-year period since 3 March 1972. Effective 28 March 1995, the period of qualifying service for the award was reduced from four years to three years; however, this change was not retroactive. Service must have been consecutive and service performed in the Reserve Component of the U.S. Air Force, Navy, Marine Corps, or Coast Guard may not be credited for award of this medal. The member must have exhibited honest and faithful service in accordance with the standards of conduct, courage and duty required by law and customs of the service of a member of the same grade as the individual to whom the standard is being applied. A member must be recommended for the award by his or her unit commander whose recommendation is based on personal knowledge of the individual and the individual’s official records of periods of service under prior commanders during the period for which the award is made. Furthermore, a Commander may not delay award or extend the qualifying period for misconduct. A determination that service is not honorable as prescribed negates the entire period of the award
