Established in February 1992, the United Nations Transitional Authority in Cambodia (UNTAC) incorporated the existing UN Advance Mission in Cambodia (UNAMIC). UNTAC's mandate encompassed human rights, organizing and conducting free and fair elections, military arrangements, civil administration, maintenance of law and order, repatriation and resettlement of Cambodian refugees and displaced persons, and rehabilitating essential infrastructure during the transitional period. The mission concluded on 15 November 1993. Military observers who served at least 90 consecutive days between 16 March 1992 and 15 November 1993 are eligible for the UNTAC Medal. The medal may be awarded posthumously to members killed or presumed killed while on assignment.
