British Operational Service Medal
The Operational Service Medal (OSM) was introduced on 1 January 2000 and at the same time the General Service Medal (GSM) was discontinued, with the exception of the award of the GSM for Northern Ireland. Since its introduction, three OSMs have been issued: for service in Sierra Leone, Afghanistan and the Democratic Republic of Congo. Although each OSM looks the same, separate ribbons denote each separate award. A Clasp may be awarded with the OSM to signify service in a more dangerous area or period of conflict.
