1970. From October 1970 a small group of New Zealanders, consisting of one officer and four SNCOs, were attached the AATTV. That year, as the Australians and Americans prepared to withdraw, a process of Vietnamization began, and the AATTV established a jungle training centre in Phuoc Tuy Province. Some members of the AATTV also served in Mobile Advisory and Training Teams (MATTs) operating within Phuoc Tuy Province at this time. In November 1970, the unit's strength peaked at 227, at which time the team was expanded with an intake of corporals. In 1971, the 1 ATF combat units were withdrawn and the AATTV reverted to their original role of training only. As the final 1 ATF units left the country in early 1972 the AATTV, having been reduced to around 70 personnel, remained in Phuoc Tuy to provide training and advisory assistance to the ARVN and to training Cambodian soldiers of the Force Armée Nationale Khmère (FANK). The last Australians left Vietnam in mid-December 1972 – the AATTV left on 18 December – following the election of the Whitlam Labor government. The AATTV had the longest tour of duty of any Australian unit in Vietnam, serving a total of ten years, four months and sixteen days. The unit also had the distinction of being the first Australian unit committed to Vietnam and the last to be withdrawn. Disbandment The unit was disbanded in Australia on 16 February 1973. The AATTV was Australia's most decorated unit of the war, including all four Victoria Crosses awarded during the conflict (awarded to Warrant Officer Class Two Kevin Wheatley, Major Peter Badcoe, Warrant Officer Class Two Rayene Simpson and Warrant Officer Class Two Keith Payne respectively). The unit also received the United States Army Meritorious Unit Commendation and the Vietnamese Cross of Gallantry with Palm Unit Citation. Individuals who served with the 5th Special Forces Group between 1 November 1966 and 31 January 1968 are also entitled to wear the United States Army Presidential Unit Citation. The Valorous Unit Award was also awarded to B-20, 1st Mobile Strike Force Battalion for service between 3–11 April 1970 and a few members of the AATTV are also entitled to this award. Members of the AATTV received many decorations for their service and the unit "gained the distinction of being probably the mostly highly decorated unit for its size in the Australian Army".
