The Accumulated Campaign Service Medal and the Accumulated Campaign Service Medal 2011 are medals awarded by King Charles III to members of his Armed Forces to recognise long campaign service. The original Accumulated Campaign Service Medal, instituted in January 1994, was awarded to holders of the General Service Medal (1962) who had completed 36 months (1,080 days) of accumulated campaign service. The replacement Accumulated Campaign Service Medal 2011 is now currently awarded to holders of various campaign service medals who have completed 24 months (720 days) of campaign service.
