The NATO Meritorious Service Medal consists of a blue background with gold, silver and three narrow white stripes on each outer most portion of the ribbon, and the medallion color is changed from bronze in appearance to a silver medallion for this medal only. All medals except North Macedonia's NATO Medal have corresponding campaign clasps, however some militaries (such as the United States) prohibit the wearing of the medal with a clasp and instead authorize service stars for wear on any NATO Medal while wearing any US military uniform (although the various clasps may be accepted from NATO and retained by the service member as a memento).
