33 Cold War history of Australia

The 1st Australian Task Force was a brigade-sized formation which commanded Australian and New Zealand Army units deployed to South Vietnam between 1966 and 1972. 1 ATF was based in a rubber plantation at Nui Dat, 8 kilometres (5.0 mi) north of Ba Ria in Phuoc Tuy Province and consisted of two and later three infantry battalions, with armour, aviation, engineers and artillery support. While the task force was primarily responsible for securing Phuoc Tuy Province, its units, and the Task Force Headquarters itself, occasionally deployed outside its Tactical Area of Responsibility.

The 1st Aviation Regiment is one of the Australian Army's three Army Aviation regiments and provides aerial reconnaissance and fire support to the Australian Army. The 1st Aviation Regiment, equipped with Eurocopter Tiger attack helicopters, forms part of the 16th Aviation Brigade and is based at Gaza Lines, Robertson Barracks, Darwin.

1st Battalion, Royal Australian Regiment is a regular motorised infantry battalion of the Australian Army. 1 RAR was first formed as the 65th Australian Infantry Battalion of the 34th Brigade (Australia) on Balikpapan in 1945 and since then has been deployed on active service during the Korean War, the Malayan Emergency, the Vietnam War, Unified Task Force in Somalia, East Timor, Iraq War and Afghanistan. Additionally, the battalion has deployed on peacekeeping and other operations to a number of countries including Japan, Rifle Company Butterworth, Timor Leste, Solomon Islands, Tonga and the Philippines. In 2021, 1 RAR remains one of the Australian Army's most heavily deployed units sending individuals and detachments to domestic, regional and other enduring operations. The battalion is currently based in Coral Lines at Lavarack Barracks, Townsville, Queensland, where it forms part of the 3rd Brigade.

The 3rd Battalion, The Royal Australian Regiment is a mechanised infantry battalion of the Australian Army, based in Kapyong Lines, Townsville as part of the 3rd Brigade. 3 RAR traces its lineage to 1945 and has seen operational service in Japan, Korea, Malaya, Borneo, South Vietnam, Rifle Company Butterworth, East Timor, the Solomon Islands, Afghanistan and Iraq.

The 5th Aviation Regiment is an Australian Army aviation unit. Formed in 1987 after the Army took over responsibility for operating helicopters from the Royal Australian Air Force, the regiment is based at RAAF Base Townsville, in Queensland. It currently forms part of the 16th (Aviation) Brigade and it operates the majority of the Army's transport helicopters. Throughout its existence, the regiment has been deployed overseas numerous times, supporting both peacekeeping and warlike operations. Since its formation elements of the regiment have made operational deployments to Cambodia, Papua New Guinea, East Timor, Iraq, Indonesia and Pakistan.

6th Battalion, Royal Australian Regiment is a mechanised infantry battalion of the Australian Army. It was originally raised in Brisbane, Queensland, on 6 June 1965 and has since then served in a number of overseas deployments and conflicts including South Vietnam, East Timor, Iraq and Afghanistan. During the Vietnam War, the battalion earned a US Presidential Unit Citation from the United States when members from 'D' Company participated in the Battle of Long Tan on 18–19 August 1966. The battalion is currently based at Gallipoli Barracks in Brisbane and forms part of the 7th Brigade.

The 7th Signal Regiment is an Australian Army signals intelligence (SIGINT) unit. Drawing lineage from the Australian Special Wireless Group (ASWG), which was raised during World War II, the regiment's history includes service in the Allied campaigns in Greece, on Crete and in Syria before taking part in the fighting against the Japanese in New Guinea. After the war, the ASWG was redesignated the 101 Wireless Regiment, deploying detachments overseas during the Malayan Emergency and Confrontation. In the mid-1960s, the unit became the 7th Signals Regiment, taking part in the Vietnam War. The unit is currently part of the 6th Brigade.

The 171st Aviation Squadron is an Australian Army helicopter squadron equipped with S70A Black Hawk helicopters and provides support to the Special Operations Command. The squadron is based at Luscombe Airfield, Holsworthy Barracks, Sydney and forms part of the 6th Aviation Regiment.

The Australia, New Zealand, United States Security Treaty is the 1951 collective security non-binding agreement between Australia and New Zealand and, separately, Australia and the United States, to co-operate on military matters in the Pacific Ocean region, although today the treaty is taken to relate to conflicts worldwide. It provides that an armed attack on any of the three parties would be dangerous to the others, and that each should act to meet the common threat. It set up a committee of foreign ministers that can meet for consultation.

The Australian Army is the principal land warfare force of Australia, a part of the Australian Defence Force (ADF) along with the Royal Australian Navy and the Royal Australian Air Force. The Army is commanded by the Chief of Army (CA), who is subordinate to the Chief of the Defence Force (CDF) who commands the ADF. The CA is also directly responsible to the Minister for Defence, with the Department of Defence administering the ADF and the Army.

The Australian Army Training Team Vietnam (AATTV) was a specialist unit of military advisors of the Australian Army that operated during the Vietnam War. Raised in 1962, the unit was formed solely for service as part of Australia's contribution to the war, providing training and assistance to South Vietnamese forces. Initially numbering only approximately 30 men, the size of the unit grew several times over the following years as the Australian commitment to South Vietnam gradually grew, with the unit's strength peaking at 227 in November 1970. Members of the team worked individually or in small groups, operating throughout the country from the far south to the Demilitarized Zone (DMZ) in the north. Later they were concentrated in Phước Tuy Province as Australian forces prepared to withdraw from Vietnam. It is believed to be the most decorated Australian unit to serve in Vietnam; its members received over 100 decorations, including four Victoria Crosses, during its existence. The unit was withdrawn from Vietnam on 18 December 1972 and was disbanded in Australia on 16 February 1973. A total of 1,009 men served with the unit over a period of ten years, consisting of 998 Australians and 11 New Zealanders.

The Australian Secret Intelligence Service (ASIS) is the foreign intelligence agency of Australia, tasked with the covert collection of information overseas through personal contacts and other means of human intelligence. It is part of the Australian Intelligence Community and is also responsible for counter-intelligence and liaising with the intelligence agencies of other countries. ASIS was formed in 1952 but its existence remained secret within much of the government until 1972. ASIS is comparable to the Secret Intelligence Service (MI6), and the Central Intelligence Agency (CIA).

Australian Signals Directorate is the Australian government agency responsible for foreign signals intelligence, support to military operations, cyber warfare, and information security. ASD is part of the Australian Intelligence Community. ASD's role within UKUSA Agreement is to monitor SIGINT in South and East Asia. The ASD also houses the Australian Cyber Security Centre.

The Clearance Diving Branch is the specialist diving unit of the Royal Australian Navy (RAN) whose versatile role covers all spheres of military diving, and includes explosive ordnance disposal and maritime counter-terrorism. The Branch has evolved from traditional maritime diving, and explosive ordnance disposal, to include a special operations focus.

Conscription in Australia, or mandatory military service also known as National Service, has a controversial history dating back to the first years of nationhood. Australia currently only has provisions for conscription during times of war when authorised by the governor-general and approved within 90 days by both houses of parliament as outlined in Part IV of the Defence Act 1903.

ECHELON, originally a secret government code name, is a surveillance program operated by the United States with the aid of four other signatory states to the UKUSA Security Agreement: Australia, Canada, New Zealand, and the United Kingdom, also known as the Five Eyes.

The General Dynamics F-111C is a variant of the F-111 Aardvark medium-range interdictor and tactical strike aircraft, developed by General Dynamics to meet Australian requirements. The design was based on the F-111A model but included longer wings and strengthened undercarriage. The Australian government ordered 24 F-111Cs to equip the Royal Australian Air Force (RAAF) in 1963, but the aircraft were not delivered until 1973 because of long-running technical problems. During 1979 and 1980 four of these aircraft were converted to the RF-111C reconnaissance variant. Four ex–United States Air Force (USAF) F-111As were purchased by Australia and converted to F-111C standard in 1982 to replace F-111Cs destroyed during accidents. Australia also operated 15 F-111Gs between 1993 and 2007, mainly for conversion training. The RAAF retired its remaining F-111Cs in December 2010. In Australian military and aviation circles, the F-111 Aardvark was affectionately known as the "Pig", due to its long snout and terrain-following ability.

The Malayan Emergency (1948–1960) was a guerrilla war fought in the Federation of Malaya between Communist pro-independence fighters of the Malayan National Liberation Army (MNLA), the Malayan Communist Party's (MCP) armed wing, and the armed forces of the British Empire and Commonwealth. The communist forces fought to gain independence for Malaya from the British Empire and to establish a socialist economy, while the Commonwealth forces fought to combat communism and protect British economic and geopolitical interests. The fighting spanned both the colonial period and the creation of an independent Malaya in 1957. The conflict was called the "Anti-British National Liberation War" by the MNLA, but an "Emergency" by the British for insurance purposes, as London-based insurers would not have paid out in instances of civil wars.

The Royal Australian Air Force (RAAF) operated 24 McDonnell Douglas F-4E Phantom II fighter-bomber aircraft in the ground attack role between 1970 and 1973. The Phantoms were leased from the United States Air Force (USAF) as an interim measure owing to delays in the delivery of the RAAF's 24 General Dynamics F-111C bombers. The F-4Es were considered successful in this role, but the government did not agree to a proposal from the RAAF to retain the aircraft after the F-111s entered service in 1973.

Australia's involvement in the Vietnam War began with a small commitment of 30 military advisors in 1962, and increased over the following decade to a peak of 7,672 Australian personnel following the Menzies Government's April 1965 decision to upgrade its military commitment to South Vietnam's security. By the time the last Australian personnel were withdrawn in 1972, the Vietnam War had become Australia's longest war, eventually being surpassed by Australia's long-term commitment to the War in Afghanistan. It remains Australia's largest force contribution to a foreign conflict since the Second World War, and was also the most controversial military action in Australia since the conscription controversy during World War I. Although initially enjoying broad support due to concerns about the spread of communism in Southeast Asia, an increasingly influential anti-war movement developed, particularly in response to the government's imposition of conscription.

No. 2 Squadron is a Royal Australian Air Force (RAAF) squadron that operates from RAAF Base Williamtown, near Newcastle, New South Wales. From its formation in 1916 as part of the Australian Flying Corps, it has flown a variety of aircraft types including fighters, bombers, and Airborne Early Warning & Control (AEW&C). During World War I, the squadron operated on the Western Front conducting fighter sweeps and ground-attack missions. It was disbanded in mid-1919, following the end of hostilities. The squadron was briefly re-raised in 1922 as part of the newly independent RAAF, but was disbanded after only a couple of months and not reformed until 1937. It saw action as a bomber unit in the South West Pacific theatre of World War II and, equipped with English Electric Canberra jets, in the Malayan Emergency and the Vietnam War. The squadron was again disbanded in 1982, following the retirement of the Canberra. It was re-formed in 2000 to operate the Boeing 737 AEW&C "Wedgetail". One of the six Boeing 737s was deployed to the Middle East in September 2014, as part of Australia's contribution to the military coalition against ISIS.

No. 3 Aircraft Depot was a maintenance unit of the Royal Australian Air Force (RAAF). Formed in March 1942 at RAAF Station Amberley, Queensland, its prime function initially was the assembly and despatch of combat aircraft from the United States; it also performed salvage operations. From 1942 until 1947 it took on the role of administering the Amberley base. The depot was responsible for heavy maintenance of the RAAF's English Electric Canberra jet bombers following their entry into service in 1953. In the 1970s it began maintaining and upgrading the General Dynamics F-111C swing-wing bomber, along with Bell UH-1 Iroquois and Boeing CH-47 Chinook helicopters. No. 3 AD merged with No. 482 Maintenance Squadron in March 1992 to form No. 501 Wing, which maintained the F-111 until disbanding in 2001.

No. 9 Squadron was a unit of the Royal Australian Air Force (RAAF). The squadron was formed in early 1939 and saw active service in World War II as a fleet co-operation unit providing aircrews for seaplanes operating off Royal Australian Navy cruisers. It was disbanded in late 1944, but was re-raised in 1962 and later became an Army co-operation unit, flying helicopters in support of Australian troops during the Vietnam War. The squadron was disbanded in 1989 when the RAAF transferred its battlefield helicopters to the Australian Army's aviation regiments.

No. 16 Air Observation Post Flight was a Royal Australian Air Force (RAAF) unit that saw action in World War II supporting Australian Army operations. It was formed in October 1944 and disbanded in June 1947. The flight was reestablished in September 1958, and was disbanded again in December 1960, when its responsibilities were transferred to a joint Army-RAAF unit.

No. 35 Squadron is a Royal Australian Air Force (RAAF) transport unit. Formed in 1942, No. 35 Squadron operated during World War II, transporting cargo and passengers around Australia, New Guinea and the Netherlands East Indies, equipped with a variety of aircraft including the Douglas Dakota. It was disbanded after the war, but was re-raised in the 1960s for service during the Vietnam War, flying transportation and resupply operations with DHC-4 Caribous in support of Australian and US forces. The squadron was subsequently augmented with rotary-wing aircraft, operating UH-1 Iroquois in both the transportation and gunship roles. In the late 1980s, the squadron returned to a solely fixed-wing transport role. It ceased operations in 2000, but was re-raised in January 2013. It began re-equipping with C-27 Spartan transports in 2015.

No. 79 Squadron is a Royal Australian Air Force (RAAF) flight training unit that has been formed on four occasions since 1943. The squadron was established in May 1943 as a fighter unit equipped with Supermarine Spitfires, and subsequently saw combat in the South West Pacific theatre of World War II. Between June 1943 and the end of the war in August 1945 it flew air defence patrols to protect Allied bases and ships, escorted Australian and United States aircraft, and attacked Japanese positions. The squadron was disbanded in November 1945, but was re-formed between 1962 and 1968 to operate CAC Sabres from Ubon Air Base in Thailand. In this role it contributed to the defence of Thailand against a feared attack from its neighbouring states and exercised with United States Air Force units. No. 79 Squadron was active again at RAAF Base Butterworth in Malaysia between 1986 and 1988 where it operated Mirage III fighters and a single DHC-4 Caribou transport during the period in which the RAAF's fighter squadrons were transitioning to new aircraft.

No. 82 Wing is the strike and reconnaissance wing of the Royal Australian Air Force (RAAF). It is headquartered at RAAF Base Amberley, Queensland. Coming under the control of Air Combat Group, the wing operates F/A-18F Super Hornet multirole fighters and Pilatus PC-9 forward air control aircraft. Its units include Nos. 1 and 6 Squadrons, operating the Super Hornet, and No. 4 Squadron, operating the PC-9.

No. 482 Squadron was a maintenance unit of the Royal Australian Air Force (RAAF). It was formed in May 1942 as No. 4 Repair and Salvage Unit, renamed No. 4 Repair and Servicing Unit in January 1945 and re-formed as No. 482 (Maintenance) Squadron in May 1946. The squadron then became a component of No. 82 (Bomber) Wing at RAAF Station Amberley, Queensland. Over the years it serviced the wing's Consolidated B-24 Liberators, Avro Lincolns, English Electric Canberras, McDonnell Douglas F-4E Phantoms, and General Dynamics F-111Cs.
