From Wikipedia, the free encyclopedia.
The Australian Imperial Force (AIF) was the name given to the military expeditionary force dispatched from Australia to fight overseas during World War I and World War II. The units that made up the AIF were generally army and support units (medical, engineering, etc.) and, during World War I, the aviation units of the Australian Flying Corps (AFC). Today the two AIFs are distinguished by referring to the World War I contingent as the 1st AIF and the World War II contingent as the 2nd AIF.
