Airfield Defence Guards

The Airfield Defence Guard (ADG) mustering of the Royal Australian Air Force (RAAF) performs specialist ground defence tasks to protect air power assets from hostile ground action.[1] The mustering is composed of non-commissioned members, commonly called 'ADGies,' most of whom are employed within a Security Forces (SECFOR) Squadron (SQN). Their primary role is the protection of RAAF equipment, personnel, assets and facilities during operations. While ADGs train to counter special forces as the primary ground threat to the projection of air power, ADGs are themselves conventional forces. Other duties include training RAAF personnel in weapon handling and basic ground defence tactics.

ADGs are commanded by commissioned officers known as Ground Defence Officers (GRDEFO) who receive initial training at the Australian Army's Royal Military College (RMC), Duntroon. Following graduation from RMC, GRDEFOs undertake the Army Regimental Officer Basic Course (Infantry) prior to RAAF-specific training at the RAAF Security and Fire School (RAAFSFS), RAAF Base Amberley.[1]

ADGs do not operate anti-aircraft weapons, which are the responsibility of the Army's Royal Regiment of Australian Artillery. They are comparable to the British Royal Air Force Regiment, USAF Security Forces, and the RNZAF Security Forces.

Current structure

Formerly, graduates from the RAAF Security & Fire School were placed into either 1AFDS or 2AFDS. However, in late 2013, with the future procurement of new aircraft, such as the F-35 Lightning II, both Airfield Defence Squadrons were merged with the RAAF Security Police, Airbase Protection and RAAF Military Working Dog Handlers to form Numbers 1 & 2 Security Forces Squadrons (SECFOR), boosting the strength and capability of protecting the new assets. Along with these changes, 1SECFOR was relocated to RAAF Base Williamtown, and 3AFDS was re-activated as 3SECFOR, and based at RAAF Base Edinburgh. The ADG mustering may be broadly divided into those positions contained within a Security Forces Squadron and those within other units. Within Combat Support Group, No. 95 Wing commands the three Security Forces Squadrons.[2]

Security Forces Squadrons are deployable tactical units, broadly comparable in size and structure to an infantry independent rifle company, capable of providing force protection for RAAF elements or other formations. 2AFDS comprises four Rifle Flights and a Support Flight; each Rifle Flight consists of four 10-man Sections and a Headquarters element of one GRDEFO, a SGT and a signaller. Support Flight contains communications, signals, field engineering and reconnaissance elements (including snipers) and is commanded by a GRDEFO and an ADG Flight Sergeant. 1AFDS is an integrated unit of permanent and reserve members; while it is headquartered at RAAF Base Edinburgh, South Australia, it has reserve Rifle Flights located in New South Wales, South Australia, Tasmania, Victoria and Western Australia. In recent history 1AFDS has relocated to Amberley and has gained more permanent members with 3 rifle flights and is working closely with 2AFDS.[5]

Permanent Air Force NCOs may be posted to a Ground Defence Training Section (GDTS) at any major RAAF base in Australia or to certain training units within Air Force Training Group. GDTS staff undertake both a training role and provide specialist advice to unit commanders. Reserve NCOs may be posted to a SECFOR Squadron, or to an instructional post or Reserve Airbase Protection Flight within one of the RAAF's 'City' Squadrons (Nos. 13, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30 & 31 SQNs). ADG Warrant Officers (WOFFs) may be posted to staff or policy positions within a higher headquarters.



From 1929 the RAAF began to establish an Aerodrome Defence Scheme (ADS), primarily utilizing aircrafthands to provide local defence of airfields, although it was initially limited in scope. Following the acquisition of the required equipment training began in 1931, including in both anti-aircraft and ground defence roles. Between 1931 and 1939 this also included exercises with the Army, during which Aerodrome Defence Sections defended an area against attacks by Australian Army units and RAAF aircraft. In 1939 it was directed that the scheme be expanded to include all units and stations.[6]

Second World War

While the RAAF did not face a significant ground threat in the first years of World War II, an Air Force Guard mustering was proposed in 1940.[7] This mustering was to receive training in infantry tactics to defend RAAF bases against attack and would be modelled on the Royal Air Force Regiment. The idea never progressed and those recruited for the task were assigned to other musterings. Following the bombing of Darwin in 1942 and ground attacks on Allied air bases, it was realised that the RAAF needed to defend its own airfields and that ground defence training was required for RAAF personnel. Following a request to the Army, Lieutenant Colonel H.H. Carr was seconded to the RAAF from 2/22 Battalion AIF in May 1942. Further secondments of infantry officers and NCOs followed and the RAAF Defence School was established at Hamilton, Victoria in September of that year. The school commenced training Army and RAAF officers and NCOs as Aerodrome Defence Officers and Aerodrome Defence Instructors, who were then posted to RAAF units to deliver ground defence training.[8] In October 1942, the Security Guards Unit was formed at Livingstone Field, Northern Territory.[9] All RAAF guards were posted to this unit, irrespective of where they were serving. The Security Guards Unit was charged with providing guards for operational bases both within Australia and overseas. Trainees were instructed in the employment of anti-aircraft guns, ground patrolling, scouting and hand-to-hand combat. At first the unit had a strength of 567 personnel, increasing to 943 by July 1943; in that year the unit moved to Darwin.[10] The unit was renamed No. 1 Airfield Defence Squadron in April 1945.[11]

A second unit, the Defence Pool, was established at Noemfoor in December 1944.[12] It is believed that guards may have been trained at the Security Guards Unit and then posted to the Defence Pool for operational deployment. A detachment of the Defence Pool was deployed to Morotai island in early 1945 in order to prepare a camp for the arrival of the main party of the unit. The Defence Pool was subsequently ordered to be disbanded on 28 March 1945; however a reconsideration led to the establishment of No. 2 Airfield Defence Squadron. By May of that year ADGs had participated in a number of operations, including the recapture of Tarakan,[13] Brunei and Balikpapan.[14] They had also suffered casualties, among them Leading Aircraftman Thomas Irvine and Corporal Clarence Tully[15] who were killed during Japanese raids on Tarakan airfield. LAC Irvine died on 5 May 1945[16] and is believed to be the first ADG killed by enemy action; he is buried in the Commonwealth War Graves Cemetery on Labuan Island.


Following the end of hostilities, both Airfield Defence Squadrons were disbanded on 19 November 1945.[11] Aerodrome Defence Officers (ADOs) and Aerodrome Defence Instructors (ADIs) were retained to deliver basic ground defence instruction to RAAF members during initial and continuation training. A significant proportion of RAAF National Service recruits received training in ground defence techniques. This included the use of the .303 rifle, Thompson Sub-Machine Gun, Bren Light Machine Gun and hand grenades, in addition to fieldcraft skills. No. 1 Airfield Defence Squadron was re-established at Mallala, South Australia as a National Service unit in 1951, then once again disbanded in 1952. There is evidence to suggest that the RAAF considered the introduction of an armoured car capability in the 1950s,[17] with ADIs attending training on Staghound vehicles with the Army at Puckapunyal;[18] this project was never brought to fruition.

In June 1965 a submission to the Air Board requested the establishment of 455 positions to provide for the defence of the eleven major RAAF bases in Australia, as well as overseas bases in Malaysia, Thailand and South Vietnam.[19] In the end, the ADG mustering was re-established in October 1965[20] with an authorised strength of 220 new positions in addition to the remustering of all Drill Instructors and ADIs.[21] After the outbreak of the Vietnam War, Australia was asked to increase its level of commitment. To meet these new demands, the RAAF deployed a number of aircraft to Phan Rang Airbase, South Vietnam, in 1966. The USAF Security Force unit assigned to the base, asked the RAAF to contribute to the defence of the base.

Vietnam War

ADG Flights were deployed to South Vietnam with 2 Squadron at Phan Rang Air Base and No. 1 Operational Support Unit (1OSU) at Vung Tau. ADGs were also deployed to Ubon Air Base, Thailand to protect the RAAF detachment based there, including 79 Squadron flying Sabre jets. In Vietnam ADGs conducted both static security tasks and security patrols outside the base perimeter,[22] thus disrupting the Viet Cong ability to conduct stand-off attacks against the bases. Corporal N.E. Power became the first airman to win the Military Medal (MM) since the Second World War for a night action on 11 February 1970, during which an enemy reconnaissance party was successfully ambushed near the perimeter of the Phan Rang base.[23][24] Airfield Defence Guards also provided most of the door gunners on UH-1 Iroquois helicopters with No. 9 Squadron during the war.[25][26]

When the government of South Vietnam collapsed in 1975, Australia ordered the evacuation of its embassy in Saigon. The final mission undertaken by ADGs in Vietnam was to provide security for the evacuation.[27] The "last" evacuation aircraft was severely overloaded and four ADGs were left on the tarmac at Tan Son Nhut airfield, each armed with a pistol and four rounds of ammunition; a C-130 was diverted from Thailand to evacuate them later in the day.[28] Over 350 ADGs served in Vietnam,[20] six being killed in the conflict.[29] In addition to the MM awarded to Powers, GRDEFOs and ADGs were awarded an MBE, eight mentions in dispatches and four Distinguished Flying Medals of the ten awarded to RAAF members.[30]


After withdrawal from Vietnam the ADG mustering was reduced in numbers, with Rifle Flights posted to RAAF Bases Amberley, Fairbairn, Richmond and Williamtown and ADGs manning instructional posts at other establishments.[31] Although the RAAF contemplated disbanding the mustering in the mid-1980s, the years between the Vietnam War and the 1999 deployment to East Timor were spent consolidating tactics and techniques such as reconnaissance skills and Quick Reaction Force (QRF) operations. 2AFDS was reformed on 17 March 1983[32] with the headquarters located at RAAF Base Richmond and the Rifle Flights remaining dispersed; the unit was eventually consolidated at RAAF Base Amberley in January 1989. It regularly deployed on RAAF and joint exercises such as those in the Kangaroo series along with occasional deployments to Malaysia and New Zealand.

New capabilities were trialled, such as scout dogs to aid in detection and tracking of enemy parties and the employment on Exercise Pitch Black 1990 of M113 Armoured Personnel Carriers from the Army's 2nd Cavalry Regiment to provide armoured mobility for the QRF. Both capabilities may be considered to have matured in recent years with the attachment of Security Police (SECPOL) Military Working Dog (MWD) teams to ADG patrols and the introduction into RAAF service of the Bushmaster Infantry Mobility Vehicles.[33] In 1992 2AFDS became the first non-flying unit to be awarded the Duke of Gloucester Cup.[34]

The period saw a generational change in weapons and equipment on issue to ADGs; jungle green uniforms were replaced by the Disruptive Pattern Combat Uniform (DPCU), the L1A1 Self-Loading Rifle (SLR), M16 and F1 Sub-Machine Gun were replaced by the F88 Austeyr assault rifle and Vietnam-era radios were replaced with the Raven series of VHF and HF sets. ADGs continued to deliver weapon and ground defence training to RAAF personnel and provided the majority of instructors for recruit, apprentice and initial officer training. The scope of this role, the longest and most continuous of the ADG mustering and its predecessors, may be gauged by the delivery of conversion training from the L1A1 SLR to the F88 rifle for every member of the RAAF; at the same time the Ground Defence Training Sections, manned on each base by 3–5 ADGs and GRDEFOs, commenced delivery of additional ground defence training for all RAAF members as the service transitioned to an expeditionary role.

In 1992 1AFDS was reformed at RAAF Base Tindal, Northern Territory as a Ready Reserve unit. The Ready Reserve Scheme involved recruits enlisting for 12 months full-time service, completing identical recruit and trade training to that undertaken by regular airmen, followed by 4 years part-time service.[35] The cadre staff of 1AFDS consisted of Permanent Air Force (PAF) GRDEFOs and ADG NCOs; while the Ready Reserve Scheme was abolished in 1996, the RAAF implemented the Ground Defence Reserve Group based upon a similar concept, although with the full-time service commitment reduced to 9 months. This scheme is still in operation.

As individuals or in small groups, ADGs and GREDFOs deployed on peacekeeping operations in the Sinai and Bougainville, were attached to Army units providing Rifle Company Butterworth rotations and deployed to the Middle East with No. 33 Squadron in 1998. 2AFDS also deployed a Rifle Flight to assist with the evacuation of civilians from Cambodia in 1997 as part of Operation Vista.[3]

East Timor

Whilst preparing for deployment to Exercise Crocodile 99, 2AFDS, along with No. 381 Expeditionary Combat Support Squadron (381ECSS) and 382ECSS, were warned out for duty in East Timor on Operation Warden. Both 381ECSS and 382ECSS had ADGs and GRDEFOs on strength. 2AFDS and 381ECSS commenced deployment to Comoro Airfield, Dili, on 20 September 1999;[36] 381ECSS began arriving at Cakung Airfield, Baucau on 11 October 1999.[37] 2AFDS undertook static security, access control and reconnaissance patrol tasks, in addition to establishing observation posts and providing a Quick Reaction Force (QRF). Reinforcements arrived on 4 November 1999 comprising 37 members of 3AFDS,[38] an integrated permanent and reserve squadron headquartered at RAAF Base Amberley (subsequently disbanded in December 2006). The additional manpower also allowed the squadron to assume responsibility for the Dili heliport in December.[39]

2AFDS was awarded a Meritorious Unit Citation and the Commanding Officer, Squadron Leader J.D. Leo, received the Distinguished Service Medal for performance during Operation Warden.[40]

Solomon Islands

ADGs and GRDEFOs deployed to Henderson Field, Honiara as part of the RAAF component of Joint Task Force 635 on Operation Anode, the ADF contribution to the Regional Assistance Mission to Solomon Islands (RAMSI). Following severe rioting in April 2006, members of 2AFDS were deployed as part of the ADF response to support police in reestablishing law and order. A further link with the Solomon Islands exists via Protective Service Officer Adam Dunning of the Australian Federal Police, who was shot and killed in Honiara in December 2004. Although deployed to the Solomon Islands in his civilian role, Dunning was a reservist ADG and had previously served with 2AFDS in East Timor.

As part of Operation Catalyst, ADGs provided force protection to the RAAF air traffic control detachment at Baghdad International Airport, during 2003–04.[41] Thirteen ADGs from 2AFDS deployed to Baghdad with Security Detachment (SECDET) 13, the Australian combat team providing security for the Australian Embassy and close protection for officials.[42] The ADGs were integrated within the infantry component of SECDET 13, drawn from the 7th Battalion, Royal Australian Regiment (7RAR). The Commanding Officer 7RAR, Lieutenant Colonel Shane Gabriel, commenced his military career as an RAAF GRDEFO, serving with 2AFDS and as Base Ground Defence Officer, RAAF Base Tindal; he has also served with the RAF Regiment.[43]


The RAAF Control and Reporting Centre, based at Kandahar airport, included an embedded ground defence element which provided specialist force protection advice.[44] This deployment formed part of Operation Slipper, the ADF contribution to the International Security Assistance Force (ISAF). ADGs continue to be deployed to the Middle East Area of Operations (MEAO) in small numbers to provide specialist support to operations.

Other operations

In addition to the major campaigns listed above, in recent years ADGs have been involved in a range of smaller scale operations. These have included Operation Gold, the provision of ADF support to the Sydney Olympic Games in 2000; Operation Deluge, the provision of security to the 2007 Asia-Pacific Economic Co-operation Forum meetings in Sydney; and Operation Ramp,[45] the evacuation of Australian and foreign nationals from Lebanon in 2006 during the conflict between Israeli forces and Hezbollah.

2AFDS was presented with a squadron standard by the Governor-General of Australia, Her Excellency Ms Quentin Bryce, at RAAF Base Amberley on 19 May 2011[46]

Members are enlisted as ADGs in the Permanent Air Force for an initial period of service of four years; those joining the Ground Defence Reserve Group are employed on full-time service for 11 months, followed by 4 years part-time service. Once a candidate has successfully completed RAAF recruit training they attend the 15-week ADG Basic course at the RAAF Security and Fire School (RAAFSFS) RAAF Amberley, Queensland. Upon completion of trade training ADGs may wear the blue-grey beret which identifies them as a ground defence specialist.

Airmen graduate from ADG Basic course with the rank of Aircraftman (AC) and are posted to one of the 3 Security Forces Squadrons. Following a further 12 months service and favourable reporting, ADGs are reclassified to the rank of Leading Aircraftman (LAC). Post-graduate training may be undertaken to qualify in communications, field engineering/assault pioneer, direct fire support weapons, close personal protection and sniping;[47] the majority of these courses being undertaken at Army training establishments. Further promotion is based upon minimum periods in rank, successful completion of appropriate trade and promotion courses, performance reporting and availability of positions. All ADGs must qualify as weapon instructors prior to promotion to NCO rank. Out of mustering postings may be available, with ADGs having served within Australia's Federation Guard, as career advisers within a Defence Recruiting Centre and as Military Skills Instructors (MSIs) at No. 1 Recruit Training Unit (1RTU), RAAF Base Wagga Wagga and Officer Training School (OTS), RAAF Base East Sale.

Duties and mission roles

ADGs form the basis of the Air Force's ground combat force, protecting Base assets, infrastructure and personnel against attack by enemy ground forces. For planning purposes, a nominal Area of Operations (AO) for RAAF ground defence is usually extends to five kilometres from the airfield perimeter fence; in practice, however, the AO assigned to ADGs is determined by variables such as available forces, terrain, vegetation etc. ADGs are trained and equipped to locate, fix and destroy enemy ground forces, ideally during the reconnaissance phase of any intended attack on RAAF assets. This is achieved by the deployment of multiple patrol teams, usually consisting of 4–5 members, undertaking reconnaissance patrols, observation and listening posts. These teams are supported by specialist elements including snipers operating in a counter-sniper role. Once the enemy are located, forces are concentrated to engage and destroy their capability to complete their task. ADGs also provide a Base Commander with a Quick Reaction Force (QRF) mounted in wheeled vehicles. QRF teams are heavily armed and act as a mobile reserve to provide a counter-attack or counter-penetration capability should an enemy evade the patrol screen.

In addition to their operational role ADG instructors provide essential ground defence training to the remainder of the RAAF. This includes instruction in weapon handling, ground defence and security tactics and Chemical, Biological, Radiologican and Nuclear (CBRN) defence. Non-Commissioned Officers (NCOs) may be posted to instructional positions at 1RTU; OTS; the Australian Defence Force Academy (ADFA), Canberra; Combat Survival Training School (CSTS, also known as COMSURV), RAAF Base Townsville; RAAF Security & Fire School, RAAF Base Amberley or a Ground Defence Training Section (GDTS) at any RAAF Base in Australia.

The weapons and equipment issued to ADGs are similar to standard Australian infantry equipment.


The primary weaponry used by ADGs consists of the F88 Austeyr (with or without the M203 Grenade Launcher Attachment), F89 Minimi, and the Browning Hi-Power Self Loading Pistol. While the other weapons are occasionally used, they are more dependent on the specific role of the operator.

Australian contribution to the 2003 invasion of Iraq

The Howard Government supported the disarmament of Iraq during the Iraq disarmament crisis. Australia later provided one of the four most substantial combat force contingents during the 2003 invasion of Iraq, under the operational codename Operation Falconer. Part of its contingent were among the first forces to enter Iraq after the official "execute" order. The initial Australian force consisted of three Royal Australian Navy ships, a 500-strong special forces task group, two AP-3C Orion maritime patrol aircraft, two B707 Air-to-Air refuelling aircraft, C-130 Hercules transport aircraft and No. 75 Squadron RAAF (which included 14 F/A-18 Hornet fighters). Combat forces committed to Operation Falconer for the 2003 Invasion were withdrawn during 2003. Under the name Operation Catalyst, Australian combat troops were redeployed to Iraq in 2005, however, and assumed responsibility for supporting Iraqi security forces in one of Iraq's southern provinces. These troops began withdrawing from Iraq on 1 June 2008 and were completely withdrawn by 28 July 2009.

Corps of Staff Cadets

The Corps of Staff Cadets (CSC) is a corps of the Australian Army. It is ranked first in the Order of Precedence ahead of the Royal Australian Armoured Corps. The CSC is the corps to which all officer trainees, known as staff cadets, who attend the Royal Military College, Duntroon are allocated once they have completed their initial stage of training in III Class, known as Initial Cadet Training. Upon completion of this training, which lasts between six and eight weeks, the successful III Class cadets are welcomed into the Corps and presented with their Corps lanyard at what is known as the "Lanyard Parade". The name of the Corps of Staff Cadets is derived from the earliest history of the College, which was set up in 1911 to train officers to fill positions in the now defunct Staff Corps. Currently, however, following graduation, the cadet is promoted to the rank of lieutenant and allocated to a combat, combat support or combat service support corps, such as the Royal Australian Infantry Corps, Royal Australian Engineers, Royal Australian Armoured Corps, Royal Australian Corps of Transport, Royal Australian Artillery, etc.


Infantry is the branch of an army that engages in military combat on foot, distinguished from cavalry, artillery, and tank forces. Also known as foot soldiers, infantry traditionally relies on moving by foot between combats as well, but may also use mounts, military vehicles, or other transport. Infantry make up a large portion of all armed forces in most nations, and typically bear the largest brunt in warfare, as measured by casualties, deprivation, or physical and psychological stress.

The first military forces in history were infantry. In antiquity, infantry were armed with an early melee weapon such as a spear, axe or sword, or an early ranged weapon like a javelin, sling, or bow, with a few infantrymen having both a melee and a ranged weapon. With the development of gunpowder, infantry began converting to primarily firearms. By the time of Napoleonic warfare, infantry, cavalry, and artillery formed a basic triad of ground forces, though infantry usually remained the most numerous. With armoured warfare, armoured fighting vehicles have replaced the horses of cavalry, and airpower has added a new dimension to ground combat, but infantry remains pivotal to all modern combined arms operations.

Infantry have much greater local situational awareness than other military forces, due to their inherent intimate contact with the battlefield ("boots on the ground"); this is vital for engaging and infiltrating enemy positions, holding and defending ground (any military objectives), securing battlefield victories, maintaining military area control and security both at and behind the front lines, for capturing ordnance or materiel, taking prisoners, and military occupation. Infantry can more easily recognise, adapt and respond to local conditions, weather, and changing enemy weapons or tactics. They can operate in a wide range of terrain inaccessible to military vehicles, and can operate with a lower logistical burden. Infantry are the most easily delivered forces to ground combat areas, by simple and reliable marching, or by trucks, sea or air transport; they can also be inserted directly into combat by amphibious landing, or for air assault by parachute (airborne infantry) or helicopter (airmobile infantry). They can be augmented with a variety of crew-served weapons, armoured personnel carriers, and infantry fighting vehicles.

Knight's Armament Company SR-25

The SR-25 (Stoner Rifle-25) is a designated marksman rifle and semi automatic sniper rifle designed by Eugene Stoner and manufactured by Knight's Armament Company.The SR-25 uses a rotating bolt and a direct impingement gas system. It is loosely based on Stoner's AR-10, rebuilt in its original 7.62×51mm NATO caliber. SR-25 barrels were originally manufactured by Remington Arms with its 5R (5 grooves, right twist) rifling, with twist 1:11.25. The heavy 20-inch (510 mm) barrel is free-floating, so handguards are attached to the front of the receiver and do not touch the barrel.

No. 2 Security Forces Squadron (2 SECFOR) is an Australian military unit whose primary role is to protect and defend airfields, buildings, equipment, and personnel.

No. 3 Security Forces Squadron RAAF

The No. 3 Security Forces Squadron (3 SECFOR) is an RAAF military unit whose primary task is to protect airfields, equipment, buildings and personnel.

Originally designated No. 3 Airfield Defence Squadron (3AFDS), in the mid-2000s, the squadron was disbanded and its resources dispersed between No 1AFDS (RAAF Edinburgh) and No 2AFDS (RAAF Amberley).On 4 July 2013, the RAAF's security capability was reorganised. Subsequently, No. 3 Security Forces Squadron was formed, with its headquarters based at RAAF Base Edinburgh.

RAAF Base Richmond

RAAF Base Richmond (IATA: XRH, ICAO: YSRI) is a Royal Australian Air Force (RAAF) military air base located within the City of Hawkesbury, approximately 50 kilometres (31 mi) north-west of the Sydney central business district in New South Wales, Australia. Situated between the towns of Windsor and Richmond, the base is the oldest base in New South Wales and the second oldest in Australia. The base is home to the transport headquarters RAAF Air Lift Group, and its major operational formations, Nos. 84 and 86 Wings. The main aircraft type operated at the base is the Lockheed C-130 Hercules. Richmond is a regular venue for air shows and has at times been mooted as a site for Sydney's proposed second international airport.

Sited on a piece of land originally known as Ham Common, Richmond became an RAAF base in 1925. Its inaugural commander was Flight Lieutenant (later Squadron Leader) Frank Lukis, who also led the base's first flying unit, No. 3 Squadron. Many other squadrons were formed at Richmond in the ensuing years, as well as a separate Station Headquarters and No. 2 Aircraft Depot in 1936. The base expanded further during World War II, with more squadrons and other units being established there, including No. 1 (Fighter) Wing and No. 3 RAAF Hospital. It was not until after the war that it became the RAAF's transport hub, with the arrival of No. 86 Wing and its complement of C-47 Dakotas. The base began operating the Hercules in 1958, augmented in later years by the DHC-4 Caribou and Boeing 707.

RAF Force Protection Force Headquarters

The RAF Force Protection Force Headquarters was created in 2004 as the successor to the Tactical Survive to Operate Headquarters (Tac STO HQ). It controls the Force Protection Wings which are tasked with protection of RAF stations in the UK and overseas. Each Wing is based around a mix of RAF Regiment squadrons, with additional RAF Police, RAF Intelligence, and other support staff.

RAF Regiment

The Royal Air Force Regiment (RAF Regiment) is part of the Royal Air Force and functions as a specialist corps founded by Royal Warrant in 1942. The Corps carries out soldiering tasks relating to the delivery of air power. Examples of such tasks are Non Combatant Evacuation Operations (NEO), recovery of downed aircrew (Joint Personnel Recovery - JPR), and in depth defence of airfields by way of aggressively patrolling a large area of operations outside airfields in hostile environments. In addition the RAF Regiment provides Joint Terminal Attack Controllers (JTACs) to the British Army and Royal Marines, and provides a platoon size commitment to the Special Forces Support Group.

The RAF Regiment Gunners are personnel trained in various disciplines such as infantry tactics, force protection, field craft, sniper, support Special Forces operations, CBRN (chemical, biological, radiological and nuclear) defence, equipped with advanced vehicles and detection measures. RAF Regiment instructors are responsible for training all Royal Air Force personnel in basic force protection such as first aid, weapon handling and CBRN skills.

The regiment and its members are known within the RAF as "The Regiment", "Rock Apes" or "Rocks". After basic training at RAF Halton, and a 20 week gunner course at RAF Honington, its members are trained and equipped to prevent a successful enemy attack in the first instance; minimise the damage caused by a successful attack; and ensure that air operations can continue without delay in the aftermath of an attack. RAF Regiment squadrons use aggressive defence tactics whereby they actively seek out infiltrators in a large area surrounding airfields.

RNZAF Security Forces

RNZAF Security Forces is the Royal New Zealand Air Force unit responsible for base security, ground defence, weapons training, and Air Transport Security on RNZAF aircraft. RNZAF Security Forces operates under the RNZAF Operations Squadron.

RNZAF Security Forces are more commonly known in the RNZAF simply as SECFOR. They have a similar role to other Air Force units such as USAF Security Forces, RAAF Security Force Squadrons, and the RAF Regiment however it is smaller in size compared to their UK, American and Australian counterparts. The primary role of RNZAF Security Forces is to provide the Air Force with security of aircraft and personnel, as well as protection of airfields.

Royal Australian Air Force Ensign

The Royal Australian Air Force Ensign is used by the Royal Australian Air Force and the Australian Air Force Cadets in Australia and overseas. It is based on the Australian national flag, with the field changed to Air Force blue, and the southern cross tilted clockwise to make room for the RAAF roundel inserted in the lower fly quarter. The roundel is a red leaping kangaroo on white within a dark blue ring. The ensign was proclaimed as a Flag of Australia under section 5 of the Flags Act on 6 May 1982.The southern cross is tilted so that Gamma Crucis stays in the same position as for the Australian National Flag and that Alpha Crucis is moved along the x-axis towards the hoist by one-sixth of the width of the flag. This results in the axis being rotated 14.036° clockwise around Gamma Crucis and each star is rotated in this way, although the constellation as a whole is not simply rotated.

Security Detachment Iraq (Australia)

The Security Detachment Iraq (SECDET Iraq) was the final component of Australia's contribution to coalition operations in Iraq. SECDET was based on an Australian Army combined arms combat team consisting of an infantry company group and a troop of cavalry which operated the Australian Light Armoured (ASLAV) vehicles. The force's duties included static security guarding at the Australian Embassy in Baghdad and the protection of Australian diplomats and vehicle convoys. SECDET was withdrawn in August 2011, with the firm Unity Resources Group becoming responsible for providing security for Australia's diplomatic presence in Iraq.

Security police

In some countries, security police are those persons employed by or for a governmental agency or corporations with large campuses who provide police and security services to those agencies' properties.

Security police protect their agency's facilities, properties, personnel, users, visitors and operations from harm and may enforce certain laws and administrative regulations. Most security police have at least some arrest authority. The law enforcement powers of security police vary widely: in some cases limited to those of private persons yet in others amounting to full police powers equivalent to state/provincial, or local law enforcement.

As distinct from general law enforcement, the primary focus of security police is on the protection of specific properties and persons. This causes some overlap with functions normally performed by security guards. However, security police are distinguished from guards by greater authority: often higher levels of training, and correspondingly higher expectations of performance in the protection of life and property.

In other countries, 'security police' is the name given to the secret security and intelligence services charged with protecting the state at the highest level, including responsibilities such as personal protection of the head of state, counter-espionage, and anti-terrorism.
