🇮🇳🇹🇭 India–Thailand MAITREE-XV 2026: Why This Military Exercise Matters for the Indo-Pacific

India and Thailand have begun the 15th edition of their bilateral military exercise MAITREE-XV, bringing together soldiers from the Indian Army and the Royal Thai Army for two weeks of joint training in Thailand.

At first glance, MAITREE-XV may look like another routine military exercise.

It is not.

The exercise comes at a time when the security environment across the Indo-Pacific, Indian Ocean and Southeast Asia is becoming increasingly complex. India is strengthening its Act East engagement, Thailand remains an important Southeast Asian partner, and both countries are looking for practical ways to improve military interoperability and regional security cooperation.

MAITREE-XV therefore carries significance beyond the training ground.

It is about counter-terrorism, jungle warfare, interoperability, military diplomacy, regional stability and the gradual deepening of India's strategic engagement with Southeast Asia.

What is MAITREE-XV?

MAITREE-XV is the 15th edition of the India–Thailand joint military exercise.

The 2026 exercise is being conducted from August 18 to August 31 at Vibhavadi Rangsit Camp in Surat Thani, Thailand. The Indian Army contingent departed for Thailand on August 17.

Both sides are sending 85 personnel each, making a combined force of 170 personnel.

The Indian contingent is represented primarily by troops from the 9 Gorkha Rifles, while the Royal Thai Army contingent comes from the 3rd Battalion, 25th Infantry Brigade, 5th Division.

The exercise is being conducted at company level, with particular attention to operations in:

Jungle terrain
Semi-urban environments
Counter-insurgency operations
Counter-terrorist operations
Joint planning
Tactical coordination
Interoperability

The exercise is conducted within the framework of Chapter VII of the United Nations Charter, according to India's Ministry of Defence.

1. What Exactly Will the Soldiers Do?

MAITREE-XV is not simply about soldiers marching together or displaying military equipment.

The exercise is designed around realistic joint operations.

According to India's Ministry of Defence, the programme includes:

Field exercises

Combat discussions

Lectures

Demonstrations

Operational experience-sharing

Equipment and technology demonstrations

and a final validation exercise to assess what the two sides have learned.

The objective is to make Indian and Thai troops more comfortable operating alongside each other.

That matters because interoperability is not created by signing an agreement.

It is developed through repeated training.

2. Why Jungle Warfare Matters

One of the most interesting aspects of MAITREE-XV is its focus on jungle and semi-urban environments.

India and Thailand have different security environments, but both have experience operating in difficult terrain.

For India, jungle operations have been an important component of counter-insurgency training.

Thailand also has experience dealing with security challenges in difficult terrain and conducting operations where conventional battlefield tactics are not enough.

Jungle warfare creates unique challenges:

Limited visibility
Difficult communications
Restricted vehicle movement
Navigation problems
Small-unit operations
Intelligence gathering
Ambush risks
Medical evacuation challenges
Drone surveillance
Rapid changes in terrain

This makes joint training particularly useful.

3. Why 9 Gorkha Rifles' Participation Matters

The Indian contingent is represented primarily by troops from 9 Gorkha Rifles.

Gorkha units have a long history within the Indian Army and extensive experience in demanding operational environments.

For MAITREE-XV, however, the important point is not simply the identity of the regiment.

The bigger objective is to transfer tactics, techniques and operational experience between the two armies.

India's Ministry of Defence says the exercise will allow both contingents to exchange operational experience and showcase contemporary equipment and technologies used during joint operations.

That exchange can be valuable because modern counter-terrorism operations increasingly combine traditional infantry skills with:

Drones
Surveillance systems
Digital communications
Precision intelligence
Electronic systems
Rapid medical evacuation
Real-time command and control

4. MAITREE Is More Than Just a 2026 Exercise

The history of MAITREE goes back to 2006.

India's Ministry of Defence describes it as an important platform for sharing best practices and strengthening military cooperation between the two countries.

The exercise has traditionally alternated between India and Thailand.

The previous edition, MAITREE-XIV, was held at the Foreign Training Node in Umroi, Meghalaya, in September 2025.

That continuity is important.

Military relationships are built over years, not through one exercise.

MAITREE provides both armies with a recurring opportunity to understand how the other force operates.

5. What Happened in the Previous Exercise?

The 2025 MAITREE exercise provides useful context for understanding the current edition.

MAITREE-XIV focused on company-level counter-terrorism operations in semi-urban terrain under Chapter VII of the UN Charter.

The programme included tactical drills, joint planning, special weapons skills, physical training and raiding operations, culminating in a validation exercise designed to simulate realistic operational conditions.

This shows that the 2026 exercise is not an isolated event.

It represents the continuation of a structured military relationship.

6. India's Bigger Strategy: The Act East Policy

This is where MAITREE-XV becomes much more interesting geopolitically.

India's relationship with Thailand is part of the country's broader Act East Policy.

Thailand occupies an important geographical position between South Asia and mainland Southeast Asia.

For India, deeper engagement with Thailand can help strengthen connections with the wider ASEAN region.

Military exercises are one part of that engagement.

Economic connectivity, diplomacy, maritime cooperation and regional institutions are other parts.

Therefore, MAITREE should not be viewed only through a military lens.

It is also an example of military diplomacy supporting India's wider regional strategy.

7. Why Thailand Matters to India

Thailand is geographically important.

It sits at the crossroads of mainland Southeast Asia and has access to both the Gulf of Thailand and the Andaman Sea.

For India, this makes Thailand relevant to the wider security architecture stretching from the Bay of Bengal to Southeast Asia.

India has been increasingly interested in improving connectivity and strategic engagement with ASEAN countries.

Thailand can serve as an important bridge in that process.

The relationship therefore extends beyond army-to-army cooperation.

8. The Maritime Dimension Is Becoming More Important

MAITREE-XV is an Army exercise, but India–Thailand defence relations are increasingly broader than land warfare.

A particularly important development came in February 2026, when the Indian Air Force conducted an in-situ joint exercise with the Royal Thai Air Force in the Indian Ocean Region.

Indian Su-30MKI fighters participated, while Thailand operated SAAB Gripen aircraft.

Indian IL-78 aerial refuelling tankers supported extended-range operations, while IAF AWACS and Thai ground-control capabilities were also involved. The Indian aircraft operated from bases in the Andaman and Nicobar Islands, while Thai Gripens operated from Thailand.

This is strategically significant.

It shows that India–Thailand military cooperation is expanding across different domains.

Army → Air Force → Maritime security → Wider Indo-Pacific cooperation

That is a much bigger picture than MAITREE alone.

9. India and Thailand Are Also Discussing Defence Industry

Another major development came in June 2026.

During the 10th Thailand–India Defence Dialogue in Bangkok, the two countries discussed ways to deepen cooperation in defence manufacturing, research, innovation and capability development.

The talks also covered military-to-military engagement, capacity building, training exchanges and maritime cooperation. Both sides discussed the changing Indo-Pacific security environment.

This is potentially one of the most important long-term aspects of the relationship.

Military exercises build trust.

But defence-industry cooperation can create a much deeper relationship.

If India and Thailand increasingly cooperate on:

Defence technology
Manufacturing
Research
Training
Maritime surveillance
Military equipment
Innovation

then the relationship could gradually become more strategically significant.

10. Is MAITREE-XV About China?

This is where careful analysis is necessary.

There is no official indication that MAITREE-XV is directed against China.

The stated purpose is military cooperation and joint counter-insurgency/counter-terrorism training.

Therefore, it would be misleading to describe the exercise as an anti-China military drill.

However, the wider strategic environment cannot be ignored.

China is increasingly important to the security calculations of countries across the Indo-Pacific.

India and China have their own strategic competition.

Thailand, meanwhile, maintains its own relationship with China while also cooperating with India, the United States, ASEAN and other regional partners.

That means Thailand's strategic importance cannot be reduced to choosing one side.

11. India's Indo-Pacific Strategy

India's Indo-Pacific strategy is generally built around partnerships rather than a formal military bloc.

India works with countries including:

Thailand
Indonesia
Singapore
Vietnam
Japan
Australia
France
United States
ASEAN partners

MAITREE fits into this broader network.

The goal is not necessarily to create a new military alliance.

Instead, India is building multiple overlapping partnerships.

That gives New Delhi greater strategic flexibility.

12. Why Thailand Is Important for ASEAN

Thailand is a member of ASEAN, and India considers ASEAN central to its Indo-Pacific engagement.

That makes bilateral military cooperation with Thailand relevant to India's broader ASEAN strategy.

India and ASEAN have already emphasized cooperation in areas including:

Maritime security
Counter-terrorism
Cybersecurity
Humanitarian assistance
Disaster relief
Defence cooperation
Peacekeeping

India's wider ASEAN engagement also includes military exercises and maritime cooperation.

MAITREE therefore contributes to a larger network of regional security relationships.

13. What Does Thailand Gain?

The relationship is not one-sided.

Thailand gains opportunities to:

Improve interoperability

Thai soldiers train with Indian troops and learn different operational approaches.

Exchange tactical experience

Both sides can compare procedures and lessons learned.

Strengthen counter-terrorism capabilities

Joint training can improve preparedness for non-conventional threats.

Expand military diplomacy

Thailand can deepen its defence relationship with another major Asian power.

Improve regional connectivity

Military cooperation complements Thailand's broader engagement with India and ASEAN.

14. What Does India Gain?

For India, the benefits are equally significant.

Better understanding of Southeast Asian militaries

India gains practical experience working with Thai forces.

Stronger Act East engagement

Military cooperation reinforces diplomatic and economic engagement.

Greater regional presence

India demonstrates that its security interests extend into Southeast Asia.

Counter-terrorism cooperation

Both countries can exchange lessons from different operational environments.

Strategic relationships

Regular exercises create relationships between officers and soldiers that can remain valuable for years.

15. The Bay of Bengal and Andaman Connection

One of the most interesting strategic aspects is geography.

India's Andaman and Nicobar Islands sit close to Southeast Asia and near important maritime routes.

Thailand lies on the opposite side of the Andaman Sea.

That geography naturally creates opportunities for cooperation.

The February 2026 India–Thailand air exercise demonstrated how forces operating from the Andaman and Nicobar region can interact with Thai aircraft.

This does not mean India and Thailand are creating a military bloc.

But it demonstrates the practical value of geographical proximity.

16. Counter-Terrorism Remains the Core Mission

The most important thing to remember is that MAITREE-XV is primarily a counter-insurgency and counter-terrorism training exercise.

Its official objectives are not about preparing for a conventional war between major powers.

The focus is on situations where soldiers must operate in complex terrain against irregular threats.

This can include scenarios requiring:

Small-unit tactics
Intelligence gathering
Coordinated movement
Communications
Surveillance
Tactical planning
Civilian-sensitive operations
Medical support
Joint command structures

The exercise is therefore relevant to real-world security problems that are often very different from traditional large-scale warfare.

17. Why the UN Charter Reference Matters

The exercise is designed around joint counter-insurgency and counter-terrorist operations under Chapter VII of the UN Charter.

This is important because Chapter VII deals with action concerning threats to peace, breaches of peace and acts of aggression.

The reference places the exercise within an international legal and peace-and-security framework rather than presenting it simply as bilateral military competition.

18. Is This a Sign of a New India–Thailand Military Alliance?

No.

That would be an overstatement.

MAITREE-XV is a bilateral military exercise, not a new mutual-defence treaty.

India and Thailand are strengthening defence cooperation, but that does not mean either country is automatically committed to entering a conflict on behalf of the other.

The distinction is important.

Military cooperation can increase trust and interoperability without creating a formal alliance.

19. The Larger Indo-Pacific Picture

The Indo-Pacific is becoming increasingly interconnected.

Events in one part of the region can affect another.

Consider the geography:

India → Andaman Sea → Thailand → South China Sea → Philippines → Taiwan

This does not mean these countries form one military chain.

But it shows why Southeast Asia matters to India's strategic planning.

India's growing defence engagement with Thailand is therefore part of a wider effort to remain connected to developments east of the Indian Ocean.

20. Could MAITREE Expand in the Future?

Potentially, yes.

The direction of India–Thailand defence relations suggests opportunities for deeper cooperation.

Future areas could include:

Air-force interoperability

The 2026 IAF–RTAF exercise already provides a foundation.

Maritime domain awareness

Both countries have interests in monitoring their surrounding maritime environments.

Humanitarian assistance and disaster relief

This is particularly relevant to the Indo-Pacific, where natural disasters regularly affect coastal and island communities.

Defence technology

The June 2026 Defence Dialogue specifically highlighted manufacturing, research, innovation and capability development.

Cybersecurity

Digital threats increasingly affect military and national security.

21. What Should We Watch During MAITREE-XV?

The exercise runs until August 31, so the final days may provide additional information.

Watch for:

1. The culminating validation exercise

This should demonstrate whether the two forces can operate together effectively.

2. Equipment demonstrations

The two sides are expected to showcase contemporary equipment and technologies.

3. Tactical lessons

The exchange of operational experience could provide clues about future cooperation.

4. Senior military engagement

Visits and discussions around the exercise could indicate the political importance attached to the relationship.

5. Future exercises

The real measure of MAITREE's success will be whether cooperation expands after August 31.

22. The Real Strategic Meaning of MAITREE-XV

The biggest mistake would be to judge this exercise only by the number of soldiers involved.

170 soldiers is not a large military force.

But military diplomacy is not measured only in troop numbers.

A relatively small exercise can produce something strategically valuable:

trust.

When officers train together, they learn each other's procedures.

When soldiers operate together, they learn how their partner thinks.

When commanders communicate repeatedly, coordination becomes easier.

Over time, those relationships can become important during a real crisis.

That is the quiet power of exercises like MAITREE.

23. India–Thailand Defence Relationship: The Bigger Trend

MAITREE-XV comes after several developments showing that India–Thailand defence cooperation is broadening.

2006: MAITREE begins as a recurring bilateral military exercise.

2024: MAITREE training included activities such as jungle survival, navigation, communications, combat first aid and casualty evacuation.

2025: MAITREE-XIV focused on company-level counter-terrorism training.

February 2026: Indian and Thai air forces conducted an exercise involving Su-30MKI, Gripen, IL-78 and AWACS capabilities.

June 2026: India and Thailand discussed deeper defence-industry, research, innovation, training and maritime cooperation.

August 2026: MAITREE-XV brings the two armies together again in Thailand.

Looked at this way, MAITREE-XV is not an isolated headline.

It is another step in a long-term expansion of India–Thailand security cooperation.

24. Final Analysis: Why This Exercise Matters Now

The world is experiencing a period of intense geopolitical competition.

The United States is adjusting its global military posture.

China is expanding its military capabilities.

India is strengthening its position as a major Indo-Pacific power.

ASEAN countries are trying to maintain strategic autonomy while managing relationships with larger powers.

Thailand occupies an important position within that environment.

For India, maintaining a strong relationship with Thailand means maintaining a stronger connection with Southeast Asia.

For Thailand, closer defence cooperation with India provides another valuable strategic relationship without requiring Bangkok to abandon its other partnerships.

That is why MAITREE-XV matters.

It is not an anti-China exercise.

It is not the creation of a new military alliance.

It is not preparation for an immediate regional war.

Instead, it is something more practical:

India and Thailand are building the ability to work together before a crisis forces them to do so.

And in an increasingly unpredictable Indo-Pacific, that kind of preparation can have strategic value.

What Happens After August 31?

The real test of MAITREE-XV will begin after the soldiers return home.

Will India and Thailand expand their military exercises?

Will air-force cooperation continue?

Will maritime cooperation become stronger?

Will defence-industry collaboration produce actual projects?

Will the two countries increase cooperation through ASEAN-led security mechanisms?

Those questions will tell us whether MAITREE-XV was simply another annual exercise—or part of a much larger transformation in India–Thailand defence relations.

For now, one thing is clear:

India is looking east, and Thailand is becoming an increasingly important part of that strategic picture.
