they were designated "task forces" instead of brigades. By 1976, due to limited resources and manpower the brigade's parent formation, the 3rd Division, had become a largely hollow structure. As a result, the division's headquarters were merged with the 4th Task Force's headquarters as the 3rd Division was redesignated as the "3rd Division Field Force Group" and the 4th Task Force ceased to exist. On 1 July 1981 the formation was re-raised as the "4th Task Force", however, in 1982 it was renamed as the "4th Brigade". In 1981 the brigade's infantry battalions were the 1st and 2nd Battalions, Royal Victoria Regiment (RVR). In December 1982 the 5th/6th Battalion was raised by establishing a new BHQ and utilising some of the 1 RVR companies. Until 1987 the brigade had three infantry battalions, 1 RVR, 2 RVR and 5/6 RVR. During this period 2 RVR was renamed 8/7 RVR. In 1987 the brigade was reduced to just two infantry battalions, namely 5/6 RVR and 8/7 RVR and supporting arms. In the early 1990s the brigade was assigned to the 2nd Division. In 1991, following a force structure review, the 3rd Division was disbanded and its units were placed under the 4th Brigade's command. As a result, in the late 1990s it had a vital asset protection mobilisation role as part of the "Protective Force" in the Tindal area of the Northern Territory. 21st century Monash University Regiment (MonUR) and the 2nd/10th Medium Regiment, which had previously been assigned to the brigade, were removed from the Australian Army's Order of Battle in 2012. The Officer Cadet Company of MUR was renamed Monash University Company, and the artillery was amalgamated with 5/6 RVR as the 2nd/10th Light Battery, employing mortars rather than field artillery. The 4th Combat Engineer Regiment (4 CER) was removed from the Australian Army Order of Battle in 2013. 4 CER and 22nd Construction Regiment (22 Const Regt) were amalgamated in 2013 to form the 22nd Engineer Regiment (22 ER). Melbourne University Regiment was previously assigned to the brigade, but was transferred to the 8th Brigade when it was converted into a training formation in 2017–2018. Since 2001, the brigade has contributed personnel to deployments in Iraq, Afghanistan, East Timor and the Solomon Islands. It has also supported Australia's commitment to Rifle Company Butterworth. Within Australia, the brigade provided engineer and logistic support during the 2003 Alpine Bushfires, the 2006
