The Mixed Armistice Commissions (MAC) is an organisation for monitoring the ceasefire along the lines set by the General Armistice Agreements. It was composed of United Nations Military Observers and was part of the United Nations Truce Supervision Organization peacekeeping force in the Middle East.[1] The MAC comprised on four sections to monitor each of the four truce agreements, the Hashemite Kingdom of Jordan/Israel MAC, the Israel/Syrian MAC, the Israel/Lebanon MAC and the Egypt/Israel MAC. The various MACs were located on the cease fire lines and, through close liaison with headquarters in Jerusalem, were charged with supervising the truce, investigating border incidents, and taking remedial action to prevent the recurrence of such incidents.
