The Secretary of Defense approved a request for approval of foreign awards to US Military personnel on 7 February 1966. As a result of this approval, the Republic of Vietnam Campaign Medal with device bar (1960- ) was awarded to US Armed Forces personnel by the Government of the Republic of Vietnam per Republic of Vietnam Armed Forces Order No. 48, dated 24 March 1966. The acceptance, criteria and description was announced in the Federal Register, Volume 31, No. 147, 30 July 1966 (Title 32, Code of Federal Regulation 47).
The Republic of Vietnam Armed Forces Memorandum 2655 prescribed there were two devices to be worn on the ribbon. The first device was for the period 8 March 1949 - 20 July 1954 and is not authorized for wear by American Military Personnel. The second period was from 1 January 1960 with the last period to be decided after the war was over. The ending period remains blank, since the Republic of Vietnam Government ceased to exist before the ending period was established. The devices for the medal are in two sizes - - the large size is 1 13/64 inches in width and is worn on the suspension ribbon of the full size decoration. The regular size is 19/32 inch wide and is worn on the miniature decoration and service ribbon bar.
Since the Republic of Vietnam Campaign Medal is a foreign award, it is not issued by the United States Government. The medal may be purchased from commercial sources.
