The General Service Medal (1962 GSM, also sometimes referred to as the Campaign Service Medal), is a campaign medal of the United Kingdom introduced in 1962 to replace both the General Service Medal (1918), as awarded to the Army and RAF, and the Naval General Service Medal (1915). The 1962 GSM was awarded until 2007, when it was replaced by the Operational Service Medal. In 2015 the General Service Medal (2008) was introduced. The 1962 GSM was awarded for what were often arduous campaigns and well fought operations, evidenced by the casualties that were frequently sustained.
