The 8th Battalion, Royal Australian Regiment (8 RAR) was an Australian Army Regular infantry battalion. The battalion was formed in July 1966 as part of an expansion of the Australian Army in the mid-1960s due to the perceived threat of Communism in southeast Asia. Initially the battalion was sent to Malaysia in 1967, before later being sent to South Vietnam as part of Australia's commitment to the Vietnam War. Between November 1969 and October 1970 the battalion undertook operations as part of the 1st Australian Task Force, before being brought back to Australia. In October 1973, after Australia's involvement in Vietnam officially ended, the battalion was amalgamated with 9 RAR to form 8/9 RAR. History 8 RAR was formed at Enoggera Barracks in Brisbane on 14 July 1966 as part of the expansion of the Army during Australia's involvement in the Vietnam War. On 8 August 1966 it had a strength of 370 men, including 150 experienced soldiers who had been posted across from 1 RAR. The battalion was expanded the next month with both regular soldiers and conscripts. After a period of training 8 RAR embarked overseas in 1967. In January it was warned that it would relieve 4 RAR in Malaysia, and this movement gradually took place from 24 August to 6 November. While in Malaysia the battalion formed part of the 28th Independent Commonwealth Infantry Brigade which also included New Zealand Army and British Army units. 8 RAR returned to Enoggera in April 1969 and began intensive training ahead of being deployed to South Vietnam. The battalion arrived in South Vietnam on 17 November 1969 and replaced 9 RAR six days later. Like the other Australian Army units in Vietnam, the battalion formed part of the 1st Australian Task Force and was based in Phuoc Tuy province. In early 1970 8 RAR took part in Operation Hammersley, a reconnaissance operation in the Long Hải area. This operation began on 10 February and on 18 February it captured a large bunker complex after the Vietcong (VC) defenders withdrew following air raids. The operation continued until 9 March, with the battalion carrying out patrols and conducting ambushes in order to engage VC troops. These operations were successful, and 8 RAR was awarded the South Vietnamese Government's Meritorious Unit Commendation, including Cross of Gallantry with Palm Unit Citation for its role in the operation. 8 RAR's main task was participating
