Regiment of the Australian Army

The 3rd/4th Cavalry Regiment is an armoured unit within the Australian Army's Royal Australian Armoured Corps. Formed in 1981 with the amalgamation of the 3rd Cavalry Regiment and the 4th Cavalry Regiment, from 1986 to 2014 the unit consisted of an independent squadron, B Squadron 3rd/4th Cavalry Regiment, within the 3rd Brigade in Townsville, Queensland. From 2017, B Squadron 3rd/4th Cavalry Regiment has been the training support and logistics squadron within the School of Armour at Puckapunyal in Victoria.

The 3rd Cavalry Regiment was formed in beginning of 1967 when, as a result of a re organisation of the units of the Royal Australian Armoured Corps, the 1st Armoured Personnel Carrier Squadron which was serving in Vietnam at the time, was renamed as 'A' Squadron, 3rd Cavalry Regiment. At the same time 'B' Squadron, 3rd Cavalry Regiment was formed in Australia to provide a follow on force and relieve 'A' Squadron at the end of their tour. Equipped with the M113A1 armoured personnel carriers (APCs), its initial strength in Vietnam was 10 officers and 107 men. Both 'A' and 'B' Squadrons of the 3rd Cavalry Regiment would continue this extensive service throughout the remainder of Australia's involvement in Vietnam as part of the 1st Australian Task Force (1 ATF), with a squadron of the regiment operating there for nearly the next six years. Prior to this, however, when 'A' Squadron was relieved by 'B' Squadron on 13 May 1969, most of its personnel were transferred to 2nd Cavalry Regiment while 'B' Squadron, 3rd Cavalry Regiment finished their tour in country on 6 January 1971 when they were relieved by 'A' Squadron and returned to Australia. They remained at Townsville until they were amalgamated with the 4th Cavalry Regiment in 1981. Meanwhile, the regiment's strength in Vietnam increased over time and by August 1971 had grown to 15 officers and 154 men. 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.

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. 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. Since the late 1990s, the squadron has supported operations in Iraq, Afghanistan and Timor Leste, operating M113s in Timor as part of various commitments including INTERFET, UNTAET and later Operation Astute. In Iraq, the squadron provided personnel to crew ASLAVs assigned to SECDET, the Al Muthanna Task Group and Overwatch Battle Group (West), while the squadron deployed its Bushmaster infantry mobility vehicles to Afghanistan as part of Operation Slipper.

On 27 November 2014, B Squadron 3rd/4th Cavalry Regiment held a transition parade with the 2nd Cavalry Regiment where the squadron's personnel, materiel and facilities were transferred to the latter and the unit ceased to operate. At this time custodianship of the unit's guidons and historical collection were transferred to the RAAC Head of Corps cell within the School of Armour. On 8 July 2017 a parade was held at the School of Armour in which the School of Armour's Support Squadron was renamed B Squadron, 3rd/4th Cavalry Regiment. The Squadron retains the customs and traditions of the 3rd/4th Cavalry Regiment but is no longer an independent sub unit, being completely under command of the School of Armour. The historical collections of the 1st Armoured Personnel Carrier Squadron, the 3rd Cavalry Regiment, the 4th Cavalry Regiment and the 3rd/4th Cavalry Regiment are all held at the School of Armour.
