Established in 1950, the Republic of Vietnam National Order Medal honors military members and civilians for exceptional service, valor, or otherwise outstanding feats carried out on behalf of South Vietnam in the Vietnam War. It was the most prestigious award issued by the South Vietnamese government. The award was issued at five levels: Grand Cross, Grand Officer, Commander, Officer, and Knight.
The former Republic of South Vietnam created a series of awards to honor military members and civilians who carried out service on behalf of South Vietnam during the Vietnam War and related operations between 1949 and 1974. As the nation no longer exists, the awards are considered obsolete.
The medal is in the shape of a five-pointed star superimposed on a green wreath with elaborate embellishments. The ribbon is red with a vertical yellow stripe toward each edge.
