General Service Medal (1918 GSM)

Era: 1918 - 1962

The General Service Medal (GSM) was introduced in Army Order No. 4 dated 19th January 1923. This medal served as the Army and RAF equivalent of the Naval General Service Medal (NGSM). The GSM was awarded for service in various parts of the world, except in India and East, West and Africa.  This medal defines the (often inglorious) British retreat from Empire as well as various interventions deemed necessary due to the geopolitical imbalances generated in the aftermath of the two worlds.  This medal was intended for the Army and Air Force - the Naval General Service Medal 1915 - 1962 ran parallel with this for the Navy and Royal Marines, with similar (but not identical) bars.

Recipients of a Mention in Despatches were granted permission to wear a bronze oak leaf emblem on the ribbon for campaigns or expeditions after 11th August, 1920.


Materials:      The majority of the British medals and clasps are made of solid silver, though some were issue in bronze versions, mainly to Indian non-combatants.  The majority of the British campaign awards are circular, usually 36mm in diameter.

Ribbons:         Medals are worn suspended from their own specific ribbons. These were first made of silk but cotton was increasingly used as the nineteenth century developed.  Their own colours often have a symbolic significance: the equal stripes of the ‘1939 to 1945 Star,’ for example, are dark blue to represent the service of the Royal and Merchant Navies, red, to represent that of the Armies and light blue to represent that of Air Forces.

Ribbon width can vary slightly though it is generally 32mm wide.

Ribbon - 32 mm, purple with a central green stripe.

This medal has a total of 17 clasps which commemorate the various actions


Clasps are commonly, though not strictly correctly, also referred to as ‘bars’.  They are single-faced metal bars carried on a ribbon attached to the medal, indicating service in a particular campaign or battle.  The clasps carry side flanges to enable them to be attached to the medal and riveted to each other, so that new ones can be attached as earned.  Usually the first earned Clasp is borne nearest to the medal, so that the latest earned should be at the top, though they can be found in the wrong order.
