Cobra Gold 2026 Brings 30 Nations to Thailand for Combat, Cyber and Disaster Drills

More Than 8,000 Personnel Train Across Thailand

More than 8,000 military personnel from 30 countries are taking part in Cobra Gold 2026 in Thailand, where an amphibious landing, new space capabilities and disaster rescue training are testing how international forces work together. The 45th edition of Southeast Asia's largest and longest running multinational military exercise opened on February 24 and continues through March 6.

The Royal Thai Armed Forces and United States Indo-Pacific Command jointly host the exercise. Its opening ceremony took place at U-Tapao Royal Thai Airfield in Rayong province, with activities spread across several locations, including Chonburi and Sattahip. By February 27, participating forces had already conducted a major landing at Hat Yao beach.

General Ukrit Boontanon, Thailand's Chief of Defence Forces, presided over the opening alongside U.S. Ambassador to Thailand Sean O'Neill and Lieutenant General Matthew McFarlane, commanding general of America's First Corps. Senior military leaders from across the Indo-Pacific also attended.

Cobra Gold began in 1982 as a modest maritime training event between Thailand and the United States. More than four decades later, it brings together combat training, civilian evacuation, humanitarian assistance and operations involving digital networks and satellites.

The 2026 exercise is designated a Heavy Year, meaning it includes full field training rather than the lighter command post simulations that alternate annually. Troops must put plans into practice with ships, vehicles and personnel, alongside exercises in coordinating decisions.

O'Neill, the U.S. ambassador, told participants at the opening ceremony that the exercise must adapt as security challenges change:

As the world changes, so must Cobra Gold. We must always ensure Cobra Gold adapts to meet new challenges and improves the interoperability we need to defend our sovereignty and prosperity now, and in the future.

Interoperability means that forces from different countries can communicate, coordinate and use their equipment together. At Cobra Gold, that work stretches from getting troops ashore to keeping communications functioning during interference.

Thirty Countries Participate in Different Roles

Thailand, the United States, Singapore, Indonesia, Japan, South Korea and Malaysia are the seven full participants. China, India and Australia take part in selected activities, including humanitarian assistance programs.

Another ten countries participate through the Multinational Planning Augmentation Team framework: Bangladesh, Canada, Fiji, France, the United Kingdom, Italy, Mongolia, Nepal, New Zealand and the Philippines. This planning structure brings personnel from different militaries into the work of preparing multinational operations.

Ten more countries participate as observers through the Combined Observer Liaison Team. They include Germany, Saudi Arabia and Vietnam. The exercise therefore accommodates several levels of involvement, from full participation to selected activities and observation.

China and India have opportunities to cooperate through the humanitarian components, where the focus is on responding to emergencies. These activities provide a less intensive setting for building trust and agreeing on communication procedures that could be needed during a regional crisis.

Thailand's role as host also allows it to maintain its position as a bridge between competing powers. The participation structure brings countries with different security relationships into the same exercise without giving every country an identical training role.

Key Dates From Equipment Delivery to Field Training

Cobra Gold's opening followed an announcement about new armored vehicles for Thailand. The first major amphibious landing then took place two days after the opening ceremony, quickly moving the exercise into practical training.

• February 23, 2026: The delivery of 17 additional Stryker vehicles to the Royal Thai Army was announced.
• February 24, 2026: Cobra Gold opened at U-Tapao Royal Thai Airfield in Rayong province.
• February 26, 2026: Multinational forces conducted a major amphibious landing at Hat Yao beach.
• March 6, 2026: Cobra Gold is scheduled to conclude.

The exercise remains underway as of February 27. Its program includes amphibious operations, civilian evacuation, humanitarian assistance and disaster relief, as well as training across land, sea, air, space and cyberspace.

Space and Cyber Operations Join the Training

Cobra Gold 2026 focuses on Combined Joint All-Domain Operations, known as CJADO. In simple terms, this means coordinating different military services and countries across land, sea, air, space and cyberspace, rather than treating each area as a separate activity.

The exercise has expanded beyond traditional physical combat maneuvers to incorporate sophisticated cyber warfare training and operations using space capabilities. Its 2026 program introduces the integration of these capabilities with conventional training, reflecting how a force's movements can depend on digital networks and satellite connections.

Boontanon highlighted land, sea and air operations in his opening remarks, along with the importance of space and cyber capabilities. Geospatial intelligence and signals intelligence training also form part of the expansion. Geospatial intelligence uses information about locations and physical features; signals intelligence concerns information gathered from communications and other electronic signals.

At Hat Yao, advanced technological systems operated alongside traditional landing craft. Andrew Emslie, space integrator for Pacific Multi-Domain Training Experimentation Capability, explained that the exercise included the first integration of a U.S. Army multi-domain task force space system.

The deployable system monitors communications signals during operations. It can detect electromagnetic interference and help distinguish friendly signals from hostile ones. Emslie described the threat while speaking to military media from Camp Red Horse:

When you talk about electromagnetic warfare, an adversary would be looking to deny our capabilities, our ability to talk, communicate, all that kind of stuff,

Operators can use the system to identify where signals originate. If interference comes from friendly forces, they can coordinate changes to communications. If it comes from an adversary, they can locate an attempt to disrupt their electronic systems.

Cyber training includes simulated attacks on communications networks and defensive responses to digital intrusions. The space component includes monitoring satellite communications and ensuring GPS integrity. These capabilities support navigation and precision operations across Southeast Asia's complex geography, while protecting the networks commanders use to direct forces.

Four Nations Coordinate a Beach Landing

U.S. Marines joined troops from Thailand, Singapore and South Korea at Hat Yao beach on February 26. Dozens of amphibious vehicles, vessels moving personnel from ships to shore and landing craft approached the remote beach, with preset pyrotechnics and smoke screens creating simulated battlefield conditions.

The landing showed how conventional combat tasks remain central to Cobra Gold alongside its newer digital and space components. Moving a multinational force ashore requires naval crews, troops and supporting units to act in a coordinated sequence.

The Royal Thai Navy and U.S. Navy worked closely during the amphibious training. The American amphibious dock landing ship USS Ashland (LSD-48) arrived in Thailand carrying approximately 200 Marines and sailors from the 15th Marine Expeditionary Unit, 3rd Assault Amphibian Battalion and Combat Logistics Regiment 17.

Commander Adam Peeples, commanding officer of USS Ashland, described the ship's participation as part of a continuing relationship with Thailand and other partners:

We are honored to arrive in the Kingdom of Thailand and participate in Cobra Gold alongside our Royal Thai Navy counterparts and multinational partners,

Peeples also explained the purpose of the training:

Cobra Gold provides a vital opportunity to strengthen interoperability, reinforce longstanding relationships and demonstrate our shared commitment to the Indo-Pacific.

The amphibious landing served as the capstone event for Cobra Gold's maritime component. Four nations tested their ability to coordinate movements from ships to shore under simulated combat conditions, with precise timing required between naval gunfire support, aerial reconnaissance and beach assault elements.

Each country contributed particular capabilities to the combined force. The practical task was to make those contributions work together: reconnaissance had to inform the operation, supporting fire had to match its timing, and landing forces had to arrive in the intended sequence.

Commanders Describe a Message of Commitment

Lieutenant Colonel Matt Bride, commander of Task Force Ashland troops, presented the deployment as a demonstration of military commitment built through realistic training:

Task Force Ashland is more than a partnership. It's a statement of commitment forged in the crucible of realism,

Bride connected the work of Marines, sailors and partner forces to a wider message about regional security:

Here at Cobra Gold 26, we are sharpening the spear and honing the cutting edge of our combined military power. These alliances aren't just on paper, they're built on the sweat and shared determination of our Marines, sailors, partners and allies, creating an unshakeable foundation for regional security that potential adversaries will recognize.

The beach operation gives that message a practical setting. Personnel using different equipment and national procedures have to coordinate an actual movement, bringing the exercise's emphasis on interoperability into the field.

Evacuating Civilians and Responding to Disasters

Cobra Gold also devotes substantial resources to humanitarian assistance and disaster relief. Southeast Asia's vulnerability to natural disasters gives participating countries a reason to practice coordinated emergency responses alongside combat operations.

The program includes a major Non-combatant Evacuation Operations demonstration and a Humanitarian Assistance and Disaster Relief demonstration. Non-combatant evacuation means moving civilians out of a dangerous area, such as a conflict zone or a place struck by disaster.

Evacuation training addresses situations in which military forces must extract people rapidly. Recent global crises have given this capability greater urgency. During visits to exercise sites, O'Neill discussed the importance of civilian protection and described allied cooperation in this area as a foundation for broader security partnerships.

The humanitarian program also includes specialized search and rescue work. K9 USAR Thailand participated in the Amphibious Exercise, using search and rescue dogs in a scenario simulating the aftermath of a catastrophic tsunami.

MI-6, the royal pet dog of Her Royal Highness Princess Sirivannavari Nariratana Rajakanya, joined the exercise. The K9 units traveled from ship to shore in Amphibious Assault Vehicles to reach a simulated disaster zone where land routes had been destroyed.

Once ashore, the dogs and their teams carried out systematic searches for victims buried in debris. The scenario connected the military's ability to reach an isolated coastline with the rescue teams' ability to locate people in wreckage.

Princess Sirivannavari has long supported animal welfare and working dog programs. MI-6's participation demonstrated a practical use of those initiatives in disaster response and reflected the close cultural connections between Thailand's monarchy and its military institutions.

The royal dog's involvement attracted considerable local media interest, bringing public attention to Cobra Gold's humanitarian activities. Those activities serve two purposes within the exercise: practicing emergency response and giving countries such as China and India opportunities to cooperate in selected programs.

Seventeen Strykers Extend Defense Cooperation

The Royal Thai Army recently received 17 additional Stryker infantry fighting vehicles through the U.S. government's Excess Defense Articles program. The delivery, announced on February 23, adds to Thailand's substantial fleet of these armored vehicles. A precise total for the fleet was not given.

The Excess Defense Articles program transfers surplus American military assets to allied nations. The Stryker delivery forms part of broader U.S. cooperation with Thailand and the Royal Thai Army's effort to modernize its armored forces while retaining compatibility with American systems.

Produced by General Dynamics Land Systems, Strykers are armored vehicles with eight wheels. Their equipment includes weapons operated by remote control and capabilities for network-centric warfare, in which units share information through connected systems to coordinate their actions.

The vehicles provide better mobility than older armored personnel carriers and greater protection for infantry during conventional operations and peacekeeping missions. Their wheeled configuration offers better road mobility than tracked vehicles, supporting rapid movement across Thailand's urban centers and rural border areas.

The delivery coincides with Cobra Gold and the concurrent Hanuman Guardian exercise, allowing the equipment to be integrated into joint training scenarios. The vehicles complement Thailand's existing armored personnel carriers rather than standing apart from the army's wider modernization effort.

Under the cooperation framework, a Stryker Brigade Combat Team will deploy to Thailand to provide training in maintenance and tactics using connected military networks. Maintaining the vehicles and using their communications capabilities are both part of making the equipment useful in coordinated operations.

The transfer places Cobra Gold within a relationship that continues throughout the year. The annual exercise brings forces together, while equipment deliveries and follow-up training develop the capabilities they can use during later activities.

A Longstanding Alliance in a Competitive Region

Cobra Gold 2026 takes place amid increasing strategic competition in the Indo-Pacific. Its scale demonstrates continued American commitment to the region despite global tensions elsewhere, while Thailand's inclusion of Chinese and Indian personnel in humanitarian activities maintains opportunities for wider cooperation.

McFarlane, commanding general of America's First Corps, described a shared regional objective at the opening ceremony:

Our nations share a commitment to stability, prosperity and a peaceful region where all nations can thrive,

He followed that statement with a description of the exercise's public message:

This exercise reflects that commitment. It shows the world that we stand together.

The U.S. Embassy in Bangkok said Cobra Gold 2026 strengthens peace through shared strength with allies and partners, improves interoperability, integrates advanced technologies and builds readiness to address future challenges across the Indo-Pacific.

The exercise also falls in the year of the United States' 250th Independence anniversary. Commemorative activities are planned throughout 2026 to underscore cooperation with allies. Military officials said Cobra Gold would continue regardless of changes in U.S. administration, reflecting a relationship sustained through multiple governments in both countries.

Thailand is continuing its oldest military alliance in the region. The U.S.-Thai partnership was formalized through the 1954 Manila Pact and subsequent agreements, and has endured geopolitical shifts over seven decades.

Cobra Gold gives that treaty relationship an operational expression. Participating forces practice and validate procedures that would guide combined action during a crisis, whether the task involved security operations, civilian evacuation or disaster response.

The 30 participating countries range from NATO allies such as the United Kingdom and Germany to regional powers including Japan and South Korea. Unlike an exercise involving only two countries, this multinational structure requires participants to develop common standards and communications procedures across a much larger group.

The program connects several kinds of readiness: troops landing on a beach, operators protecting communications, teams evacuating civilians and rescuers reaching areas cut off by disaster. Through March 6, those activities will continue testing the cooperation that officials described at the opening ceremony.
