from Vietnam, beginning a drawdown of forces. In October the remaining troops moved to Vung Tau; however, a company from the 4th Battalion, Royal Australian Regiment/NZ (ANZAC) with a troop of APCs and support personnel remained at Nui Dat. In December the bulk of 'A' Squadron returned to Australia, while No. 1 Troop later moved to Vung Tau before returning to Australia in March 1972. Between 1967 and 1972 elements of the regiment served in every major operation carried out by 1 ATF, including the Tet Offensive and Battle of Coral–Balmoral in 1968, and the Battle of Binh Ba in 1969. Casualties sustained by the regiment in Vietnam numbered 20 killed and 115 wounded. 4th Cavalry Regiment The 4th Cavalry Regiment was raised in late 1971, as part of the Australian Army's plan to establish three regular cavalry units. The regiment came into being at Enoggera Barracks by redesignating 'B' Squadron, 2nd Cavalry Regiment, which had previously been based at Wacol, Queensland, and subsequently became 'A' Squadron in the new regiment. In early 1975, a regimental headquarters and a second squadron, known as 'B' Squadron, were raised to complete its establishment. Amalgamation In 1981, the decision was made to amalgamate the two regiments to form the 3rd/4th Cavalry Regiment. After this, the unit headquarters was established at Enoggera Barracks in Brisbane along with 'A' Squadron and the Technical Squadron, although 'B' Squadron, which had been transferred from the 3rd Cavalry Regiment, remained in Townsville. On 14 May 1986, while at Enoggera, His Royal Highness Prince Philip, the Duke of Edinburgh, presented the 3rd Cavalry Regiment's guidon to the 3rd/4th Cavalry Regiment. In July the same year, the decision was made to reduce the regiment to a single squadron and, as a result, the Brisbane-based elements were transferred to the 2nd/14th Light Horse Regiment, leaving 'B' Squadron in Townsville. Throughout the early 1990s, the squadron deployed on several peacekeeping operations to Africa. In 1992–93, the squadron was committed to Operation Solace in Somalia where they supported the 1st Battalion, Royal Australian Regiment deploying almost 100 personnel and 36 M113 armoured personnel carriers to the Baidoa region. Later, in 1994–95, they deployed on Operation Tamar in support of the United Nations Assistance Mission for Rwanda where they provided a section of three M113s and a support vehicle to operate with Australian medical teams. Since the late 1990s, the squadron has supported operations
