Joint Service Commendation Medal is awarded for heroism or meritorious service while assigned to a joint command or joint activity. The last of the Commendation Medals is the Joint Service Commendation Medal which was created in 1963. This award is intended for senior service on a joint military staff and is senior in precedence to service-specific Commendation Medals. As such, it is worn above the service Commendation Medals on a military uniform. As a joint award, multiple awards are denoted with an oak leaf cluster regardless of service.
