History
Established on 3 August 1983 by Secretary of Defense Caspar Weinberger, the Joint Service Achievement Medal completed the joint family of decorations by giving the combatant commands and defense agencies an award for their junior people: members below the grade of colonel whose achievement or meritorious service in a joint activity deserved recognition, but below the threshold of the Joint Service Commendation Medal. In American precedence it stands above the achievement medals of the individual services.
Its recipients are the action officers, non-commissioned officers and specialists of the joint staffs and task forces, and Australians posted into United States joint headquarters have been among them. For an Australian its wear follows the foreign awards rules, with approval and a place after all Australian honours in order of the date of award.
Design & ribbon
The medal
The medal is bronze, a star of twelve points with an eagle holding three arrows superimposed at its centre: the eagle from the seal of the Secretary of Defense, in whose name the medal is awarded, the arrows for readiness to defend by land, sea and air, and the points for vigilance in all directions. The reverse carries JOINT SERVICE around the top and ACHIEVEMENT AWARD around the base, with space at the centre for the recipient's name.
The ribbon

Red at the centre, stepping out through light blue, white, green and blue.
The ribbon has a centre stripe of red flanked on each side by stripes of light blue, white, green, white and blue.
Clasps
Further awards are marked on the ribbon in the American fashion rather than by additional medals.

Order of wear
