The Operational Service Badge (OSB) is issued with the Australian Operational Service Medal (AOSM). The OSB has two versions, military and civilian, issued with appropriate award and may be gifted to the next-of-kin of deceased members to complement the award of the AOSM.
This is the civilian version of the OSB. Before the establishment of the Australian Operational Service Medal (AOSM) in May 2012, those who received the Australian Active Service Medal were also issued with the Returned from Active Service Badge (RASB). Because the AOSM recognises all declared operational service, an Operational Service Badge (OSB) has been established to be issued on the first award of the AOSM.
The RASB will continue to be issued with the AASM for current warlike operations. In contrast with the RASB, the OSB may also be issued to the next-of-kin of deceased members to complement the award of the OSM.
