Queen Elizabeth II, approved three new long service medals, (15 years service), for members of the Australian Defence Force. These were the Defence Force Service Medal, (DFSM), for all regular personnel regardless of rank; the Reserve Force Decoration, (RFD), for Reserve Force officers only; and the Reserve Force Medal, (RFM), for all other Reserve Force personnel. The first medals were issued in 1982, and replaced the National Medal, which had been the ADF Long Service Medal from 1975 until 1982. The DFSM, RFD, and RFM, were themselves replaced in 1999-2000 by the Defence Long Service Medal, (DLSM), which was for both regular and reserve personnel who had completed 15 years service.
