For the Rhodesian medal, see General Service Medal (Rhodesia).
The General Service Medal (GSM) was first introduced in 1918 as an Army and RAF equivalent to the Naval General Service Medal (NGSM). The medal is used in place of a specific campaign medal , for example if the campaign is not very large, clasps are added to the medal to denote the campaign. Clasps issued with the medal include 'Iraq' , 'Palestine' , 'Palestine 1945-48' , 'Malaya' , 'Cyprus' and 'Canal Zone' . The medal has been awarded in two forms, 1918-1962 and 1962 onward.
