After the Second World War, the Australian Army changed from one mainly comprising part-time citizen soldiers to a new generation of Royal Military College-trained officers and professional soldiers, and it witnessed the reraising of the Australian Intelligence Corps. As such, it became part of the army’s first combat deployment of the new Australian Regular Army and its transition from jungle warfare to occupation duties in Japan, to conventional action in Korea (1950–53), and then back to jungle warfare and counterinsurgency operations with the Malayan Emergency, Konfrontasi with Indonesia and the Vietnam War. The Cold War was also dominated by Australian Army operations in a combined arms and joint environment, operating as part of a multinational force and often within a multinational command organisation.
