Overview

Brunei ranks 134th globally in the 2025 Military Power Rankings. The Royal Brunei Armed Forces (RBAF) are designed for territorial defense, regime protection, and the safeguarding of maritime sovereignty, particularly over the country’s offshore oil and gas infrastructure in the South China Sea. Though small in manpower, Brunei’s military is well-funded, highly professional, and benefits from robust bilateral defense relationships, most notably with the United Kingdom, Singapore, and other ASEAN partners.

The RBAF consists of the Land Forces, Royal Brunei Navy, and Royal Brunei Air Force, supported by a well-developed training system, elite unit specialization, and the presence of British Gurkhas permanently stationed in-country. Brunei’s military doctrine prioritizes rapid deployment, air-sea patrol, and strategic deterrence through partnerships, focusing on high-quality capability rather than force quantity. Joint exercises with Western and regional allies reinforce readiness and interoperability, especially in maritime and special operations domains.

Strengths

1. High Professional Standards and Training Quality

The RBAF is known for its elite training regimens, UK-standard officer academies, and joint operations with British and Singaporean forces, ensuring a well-disciplined and combat-ready structure despite small size.

2. Strong Naval and Air Surveillance Focus

Brunei emphasizes maritime patrols, airspace monitoring, and offshore resource protection, maintaining a capable coastal fleet, rotary-wing aircraft, and radar systems to defend its economic exclusion zones (EEZs).

3. Permanent UK Military Presence and Joint Exercises

Brunei hosts a British Gurkha battalion and facilitates UK-Brunei training deployments, bolstering defense capacity and signaling strategic deterrence without requiring large domestic force levels.

Why Brunei Is Still Ranked 134th

1. Extremely Small Force Size and Limited Equipment Inventory

With fewer than 7,000 personnel, Brunei’s military lacks heavy armor, fighter aircraft, and long-range strike platforms, making it reliant on tactical speed and external security guarantees.

2. No Strategic Power Projection or Wartime Sustainment Capability

Brunei’s forces are structured for static territorial defense, not expeditionary warfare. There are no naval landing units, combat logistics battalions, or fixed-wing combat squadrons to support regional deployments.

3. Heavy Dependence on Foreign Partners for Defense Depth

The country’s security posture hinges on the presence of UK troops, foreign-led training, and regional alignment, limiting its strategic autonomy in a protracted conflict or regional standoff scenario.

Conclusion

Brunei fields a technically proficient, elite-oriented defense force, focused on regime protection, offshore energy security, and strategic partnerships, rather than conventional warfare or regional power projection. Its financial resources, training excellence, and external alliances make it a capable niche military, despite its small scale. Brunei’s global ranking reflects its limited force size and combat platforms, not the quality or professionalism of its defense establishment.

Missile Capabilities

Brunei does not possess missile systems. Its defense relies on well-trained forces equipped with short-range anti-air and anti-ship platforms, primarily for coastal and naval defense. Strategic deterrence is enhanced through British and U.S. security guarantees.

Strategic Partnerships

Brunei maintains close military ties with the United Kingdom, which operates a training presence in-country through the British Army. It also engages in regular exercises with Malaysia, Singapore, and the United States, and is a participant in ASEAN defense cooperation frameworks. Brunei emphasizes diplomacy, modernization, and elite training over large standing forces.

Military History & Combat Experience

Brunei’s military history is shaped by internal stability efforts, colonial legacies, and a doctrine of forward partnership, rather than participation in conventional wars or high-intensity external combat.

  • Brunei Revolt (1962):
    The only direct internal conflict in Brunei’s modern history occurred when the TNKU (North Kalimantan National Army) attempted to overthrow the monarchy. The revolt was swiftly suppressed by British Gurkhas, and it reinforced Brunei’s reliance on UK military presence and internal security doctrine.

  • British Military Support and Training Legacy (1962–present):
    Since the 1962 revolt, British forces have remained stationed in Brunei, contributing to training, joint exercises, and strategic deterrence. This long-standing relationship underpins Brunei’s military professionalism and doctrinal alignment with NATO standards.

  • Regional Security Participation (2000s–present):
    Brunei contributes to multilateral military exercises, such as RIMPAC, CARAT, and ASEAN-led drills, focusing on maritime interdiction, counterterrorism, and humanitarian assistance operations, often with partners including Australia, Singapore, and the U.S..

  • South China Sea Sovereignty Patrols:
    Though not engaged in direct conflict, Brunei maintains a subtle presence in disputed areas of the South China Sea, with the Royal Brunei Navy tasked with protecting oil fields and monitoring foreign activity, particularly near the Louisa Reef.

Brunei’s defense history emphasizes prevention, elite training, and strategic alignment, with an operational focus on internal security and energy infrastructure defense, reinforced by strong external partnerships rather than combat record.
