The Royal Malaysian Air Force Ground Defence Force (RMAF GDF; ), commonly known by its historical acronym HANDAU, is a ground defence formation of the Royal Malaysian Air Force (RMAF). Operating under the RMAF Regiment, the unit provides ground defence and base security across RMAF airfields and installations.

HANDAU was formed in 1980 in response to communist insurgent attacks against RMAF installations, taking over airbase security duties from the Malaysian Army's Royal Military Police Corps. The unit's evolution is closely linked with the development of the RMAF's ground combat and special operations capabilities.

After a period in which its squadrons were reassigned as RMAF Provost units, the formation was reactivated as the RMAF Ground Defence Force in 2020. Alongside its primary role in airbase security, the reactivated force assumed expanded ground defence responsibilities. Official training includes tactical marksmanship, tracking, Military Operations on Urbanised Terrain (MOUT), force down operations, Fly Away Security (FAS), and quick-reaction counter-sabotage tactics.

HANDAU also participates in airfield seizure and recapture exercises, utilising tactical insertion via RMAF transport aircraft to support broader air operations.

History

Created as Security Forces Initially, the Royal Malaysian Air Force (RMAF) relied on the Malaysian Army's Malaysian Military Police Corps, now known as the Royal Military Police Corps, for security at its air bases. However, in 1974, a mortar attack by Malayan Communist Party members on the RMAF Kuala Lumpur Air Base caused some damage. In 1979, another mortar attack at the same base caused more serious damage, destroying an RMAF DHC-4 Caribou transport aircraft.

The 1974 incident prompted the Air Force Headquarters to revise its standard operating procedures for air base security. By the end of 1976, a team led by Group Captain Abdul Kadir Abu Bakar, Squadron Leader Lai Kiat Meng, and Flight Lieutenant Mior Rosli proposed establishing a dedicated security unit under the RMAF, modelled after the Royal Air Force's RAF Regiment. The proposal was approved, and an experimental unit was formed under Flight Lieutenant Mior Rosli's leadership. Corporal Mahazir became the first RMAF airman to receive commando training at the Special Warfare Training Centre in Malacca, followed by more airmen undergoing similar training. A year after the 1979 mortar attack, a squadron from this unit was ready for duty.

On 1 April 1980, the unit was officially established as the Royal Malaysian Air Force Ground and Air Defence Force (), taking over security responsibilities from the Malaysian Military Police Corps at the RMAF Kuala Lumpur Air Base. The unit became popularly known by its Malay abbreviation, HANDAU, and it was placed under the RMAF Security Regiment, which is now known as the RMAF Regiment.

Restructured as Military Police

In 1983, HANDAU underwent a restructuring. HANDAU incorporated additional military police roles after completely taking over the responsibilities from the Malaysian Military Police Corps. In addition to security forces and military police roles, a detachment of Malaysian Army commandos was attached to HANDAU, forming two special operations sections specialising in search and rescue and air assault roles. These sections were known as the Combat Air Rescue Team () and the Rapid Deployment Force ().

Around 1993, HANDAU's official name was changed to RMAF Provost to reflect the shift in its primary responsibilities from security forces to military police while still retaining its security forces capabilities. In 1995, Air Force Command transferred the role of air defence from the RMAF Provost to the RMAF Ground Base Air Defence. The RMAF Ground Base Air Defence, an artillery formation responsible for air defence, operates under the command of the air bases where they are stationed.

Separated from RMAF Regiment

On 17 March 1999, Air Force Headquarters detached the RMAF Provost Squadrons from the RMAF Regiment. This left the regiment comprised solely of special operations elements (the precursor to the modern RMAF Special Forces, PASKAU). Concurrently, the RMAF Regiment relocated to a new garrison at RMAF Jugra Air Base in Banting, Selangor. The provost squadrons were placed under the newly created RMAF Provost Marshal Department to oversee all military police functions within the service. The department was initially headquartered at RMAF Kuala Lumpur Air Base.

Following the decommissioning of RMAF Kuala Lumpur Air Base in 2018, the RMAF Provost Marshal Department headquarters moved to RMAF Sendayan Air Base.

Reactivation On 1 June 2020, HANDAU was reactivated as the RMAF Ground Defence Force under the RMAF's Capability Development 55 (CAP55) roadmap.

This restructuring followed a realignment of the RMAF's ground-based air defence architecture, which saw air defence assets transferred to dedicated RMAF Ground Base Air Defence units. Concurrently, several personnel from the RMAF Provost branch were reassigned to staff the reactivated HANDAU squadrons.

Assigned once again to the RMAF Regiment, the formation retained its original HANDAU moniker. While resuming its primary base protection role, its operational mandate was expanded to include specialised ground combat and tactical operations.

Roles and capabilities

Airbase security and defence HANDAU's primary role is the ground defence and security of RMAF air bases, installations, and assets. Its personnel safeguard airfield infrastructure, aircraft, equipment, and service members against armed assault, intrusion, sabotage, and other security threats. Airbase protection forms the core function of HANDAU, distinguishing it from the RMAF Special Forces (PASKAU).

Ground combat Beyond static perimeter security, HANDAU performs active ground combat and light infantry missions. Personnel receive training to operate outside fixed defensive positions, track hostiles, and counter armed threats in the areas surrounding RMAF installations. The unit's syllabus covers tactical marksmanship, tracking, Military Operations in Urban Terrain (MOUT), rapid intervention, and infantry tactics. These skills allow HANDAU to conduct mobile ground defence operations and conventional airbase protection tasks.

MOUT training prepares personnel for tactical operations in built-up areas and urban battlefields. HANDAU units were seen conducting urban combat training, demonstrating their ability to deploy beyond base perimeters.

Training also incorporates small unmanned aerial systems (sUAS) for tactical support. These platforms supply real-time reconnaissance and surveillance, with specific systems configured for strike roles. Integrating sUAS grants HANDAU teams enhanced situational awareness and organic aerial support during ground actions.

Quick reaction and specialised tasks Selected personnel within HANDAU squadrons are assigned to the Rapid Intervention Team (, TAC), which provides immediate armed response to security breaches. The TAC is trained in advanced combat marksmanship, urban combat, counter-infiltration, and Valuable and Strategic Assets in Transit (VSAIT) escort operations.

HANDAU units also provide specialised support functions across two key areas:

Force Down Operations: Securing aircraft, aircrews, and surrounding perimeters following forced landings, emergency diversions, or security incidents at unsecured locations. Fly Away Security (FAS): Deploying specialised security detachments onboard RMAF aircraft to safeguard personnel, cargo, and assets when operating at civilian airfields or austere overseas locations lacking organic RMAF force protection.

Air-mobile operations HANDAU participates in exercise scenarios involving airfield capture and recapture operations. During the 89th Malaysian Armed Forces Day demonstration in Kuantan Airbase, HANDAU personnel executed a tactical airfield assault following insertion from an RMAF C-130 Hercules transport aircraft using Tactical Air Landing Operations (TALO) procedures.

Rapid Intervention Team The Rapid Intervention Team (RIT; , TAC) serves as the primary rapid response element within HANDAU squadrons. Operating as a high-readiness tactical unit, TAC personnel undergo specialised training in combat marksmanship and immediate-intervention tactics to counter active threats, including base intrusions, sabotage, and high-risk security breaches.

Uniforms and insignia

'HANDAU' Shoulder Flash

Members of the RMAF Ground and Air Defence Force have worn the 'HANDAU' shoulder flash on their combat uniforms since the unit's establishment in 1980. The tab, which is an abbreviation of the Malay name for the RMAF Ground and Air Defence Force, was inspired by the RAF Regiment's "Mudguards" shoulder flash.

Even after the HANDAU squadrons were restructured into military police, the special forces element of the unit continued to use the 'HANDAU' shoulder flash until 2002, when they adopted the 'PASKAU' shoulder flash following a name change.

When the HANDAU squadrons were reactivated in 2020, the RMAF Ground Defence Force resumed the tradition of wearing the 'HANDAU' shoulder flash.

RMAF Ground Defence Insignia The RMAF Ground Defence insignia is a badge worn on the front left pocket of any uniform. The insignia features a crossed tekpi with a triangle in the centre, containing an owl inside the triangle. This design is set against the RMAF Regiment colours and is shaped like a shield with a castle wall design on top.

RMAF Blue Digital Camouflage Combat Uniform

The RMAF Ground Defence Force is the only ground-based combat unit that wears the new RMAF blue digital camouflage combat uniform. Other ground-based combat units, such as the RMAF Special Forces and the RMAF Ground Base Air Defence, use green tiger-striped combat uniforms.
