The Australian Active Service Medal (AASM) is an Australian military decoration. It was authorised on 13 September 1988 to recognise prescribed service in "warlike" operations, backdated to February 1975. It is awarded with a clasp to denote the prescribed operation and subsequent awards of the medal are made in the form of additional clasps. In 2012, it was announced that the medal would no longer be issued for future operations, with the AASM and the Australian Service Medal being replaced by the Australian Operational Service Medal.
