The Commonwealth Armed Forces (CAF) was first established by order of ANZUS in 1989 to serve Australia, New Zealand, and the territories under the American Provisional Administration. The CAF have increased in size since the founding of the Commonwealth of Australia and New Zealand, in order to meet the CANZ's global commitments as the heir to the United States of America. There are 4 branches of the CAF. The Australian and New Zealand Army, the Australian and New Zealand Navy, the Australian and New Zealand Air Force and the Australian and New Zealand Coast Guard.
