have approval from the government to conduct operations until January 1956, when it conducted a search and security mission in Kedah. The mission, code-named Operation Deuce, lasted until late April 1956 when 2RAR transferred responsibility of their area to the 1st Battalion, Royal Malay Regiment. In May, 2RAR conducted Operation Shark North in Perak. It was withdrawn from combat operations in August 1957 and left Malaya in October 1957. The battalion suffered 14 killed. In September 1957, 2RAR was replaced by the 3rd battalion, Royal Australian Regiment (3RAR), which began patrols as part of Operation Shark North in December. In January 1958, 3RAR began Operation Ginger, a major operation designed to disrupt the food supply to the communist forces. Ginger continued until April 1959 when Perak was declared a safe area. The battalion was withdrawn from operations in September 1959, returning to Australia in October. It had four killed during its tour. In October 1959, 3RAR was replaced by 1RAR. Following a month spent climatising to the jungle, 1RAR participated in Operation Bamboo, a deep jungle search near the Thai-Malay border. This operation met with little success, as insurgents could cross over the border into Thailand, where they could not be followed. In April 1960, 1RAR began Operation Magnet, the first operation in which Australian forces were able to cross the border into Thailand. However, Magnet did not result in any engagements. In July 1960, the Malayan Prime Minister declared the emergency over. Despite this, 1RAR continued operations until the end of its tour in October 1961. The battalion suffered two deaths during its tour. From October 1961 to August 1963, 2RAR conducted its second tour of duty in Perlis and Kedah. In 1960 the Army was restructured onto the Pentropic organisation in an attempt to improve its combat power and align it with the US Army. This organisation proved unsuccessful, however, and it reverted to its previous unit organisations in 1965. Vietnam War Australian Army's commitment into Vietnam commenced with a contingent of a specialist group called the Australian Army Training Team Vietnam (AATTV) which commenced in 1962. Later Australian troops and their supports arrived and were assigned the Phuoc Tuy province. The 1st Australian Task Force was based in the province between 1966 and 1971 and consisted of infantry battalions, a Special Air Service Squadron, an artillery regiment and supporting engineer, armoured and armoured personnel carrier squadrons.
