The Naval General Service Medal (NGSM) was instituted in 1915 for service in minor Naval war-like operations. As is the case with other ‘general service' medals the NGSM is always issued with a clasp denoting the area of operations. Subsequent service is recognised by the award of further clasps to be worn on the original medal. Members mentioned in despatches for operations recognised by the NGSM 1915-1962 after 11 Aug 1920 were approved to wear a bronze oak leaf on the medal ribbon. Clasps There have been sixteen clasps issued for the NGSM 1915-1962. These are: Persian Gulf 1909-1914 Iraq 1919-1920 NW Persia 1919-1920 NW Persia 1920 Palestine 1936-1939 SE Asia 1945-46 Minesweeping 1945-51 Palestine 1945-48 Bomb and Mine Clearance 1945-53 Malaya Yangtze 1949 Bomb and Mine Clearance, Mediterranean Cyprus Near East Arabian Peninsula Brunei Medal The NGSM 1915-62 is cupro-nickel medal with the obverse having the effigy of the reigning sovereign at time of issue.
