The term ANZAC originated as a telegraphic address for the Australian and New Zealand Army Corps, an army corps of Australian and New Zealand troops who fought against the Turks in 1915 at the Battle of Gallipoli during World War I. The Australian and New Zealand Army Corps was disbanded in 1916 and other Anzac formations were then formed and fought during that war in the Middle East and on the Western Front. The term ANZAC was used again during the Vietnam War as part of the name of battalions comprising Australian and New Zealand troops.
