Naval Reserve Meritorious Service Medal The Naval Reserve Meritorious Service Medal (NRMS) is a decoration presented by the United States Armed Forces to recognize enlisted members (officers are not eligible) of the Reserve or National Guard who have completed three years of honorable service. Medals awarded before 1997 required four years of service. The Naval Reserve Meritorious Service Medal differs from the standard Navy Good Conduct Medal in that the reserve version is bestowed for reserve duties such as drills, annual training and active duty for either training or operational support to the active duty force. Subsequent awards are denoted by Service Stars worn on the award medal. After 10 years of service, both officers and enlisted members are eligible for the Armed Forces Reserve Medal.
