History
The United Nations Truce Supervision Organization was established in 1948 to supervise the truce in Palestine after the first Arab-Israeli war, and it was the first peacekeeping operation the United Nations ever mounted; the day it began, 29 May, is now the International Day of United Nations Peacekeepers. Its unarmed military observers have watched over the ceasefire lines of the Middle East ever since, the oldest continuing United Nations mission.
For Australia the mission holds a special place: Australian military observers have served with UNTSO from 1956, under the name Operation Paladin, in what has become Australia's longest unbroken peacekeeping commitment. The medal is awarded for six months' service, and the same ribbon has been used for several related observer missions and their bars. As a foreign award it takes its place in the Australian Order of Wearing among the United Nations medals.
