Boeing Chinook (UK variants) Banner in Northern Ireland. On 2 June 1994 a Chinook flying from RAF Aldergrove to Scotland crashed on the Mull of Kintyre, Scotland killing all 25 passengers and all four crew members. The Chinook became a vital transit tool during the 1991 Gulf War in Iraq. They were used for moving troops into the region at the start of the conflict; a Chinook was used on 22 January 1991 to transport a Special Air Service (SAS) patrol on the infamous Bravo Two Zero mission. In the aftermath of the conflict as many as nine British Chinooks delivered food and supplies
History of the Australian Army was placed on heightened alert during the war, reports that elements of the SAS were deployed to the Gulf are incorrect. Following the end of the war an Australian Medical Unit of 75 personnel drawn mostly from the Army's 2nd Field Ambulance was briefly deployed to northern Iraq as Australian's contribution to Operation Provide Comfort (designated 'Operation Habitat' by the Australian Defence Force). The Australian Medical Unit operated in Northern Iraq between 16 May and 30 June 1991. In 2000, the Federation Guard was formed – this was a tri-service unit consisting of personnel from the army, RAN and RAAF
