The detail worth stopping on is three words: a Bhairav Battalion.
Exercise MOUNTAIN GUARDIAN 2026, the India–UAE joint military exercise, began on 5 October 2026 at the Foreign Training Node, Chaubatia, Uttarakhand, and runs to 18 October. 92 personnel are taking part, equally divided between the two armies. The Indian contingent is drawn from a Bhairav Battalion; the UAE's from a Mountain Infantry Battalion. Women officers and combatants from both armies are participating across specialist roles.
Bhairav battalions are barely a year old. Their appearance in a bilateral exercise tells you something about how the Indian Army intends to use them.
What a Bhairav battalion is
On Kargil Vijay Diwas, 26 July 2025, the Chief of the Army Staff, General Upendra Dwivedi, announced a package of new formations. Four names came out of it:
| Formation | Nature |
|---|---|
| Rudra | All-arms brigades — infantry, armour, artillery, special forces and support integrated under one headquarters |
| Bhairav | Light commando battalions — lean, agile, for rapid strikes and quick border deployment |
| Shaktibaan | Artillery regiments with drones and loitering munitions |
| Divyastra | Surveillance and loitering-munition batteries |
Each Bhairav battalion runs to about 250 specially trained and equipped soldiers. The first five or six were raised through 2025, five were reported fully operational by October 2025, with as many as 25 planned by early 2026, and their first public appearance came at the Army Day parade at Jaipur on 15 January 2026.
The design intent is specific and worth stating precisely, because it is easy to confuse with the special forces. A Bhairav battalion is built to produce shock effect at short notice close to the border — not to conduct deep strategic operations. That places it in the middle of what is now a three-tier commando structure:
- Ghatak platoon — the commando platoon organic to an infantry battalion, operating at battalion level
- Bhairav battalion — a lean commando battalion available to a formation, for rapid strikes near the border
- Para (Special Forces) — strategic and deep-penetration tasks
Three echelons, three radii of action. A question that offers "special forces" as a synonym for Bhairav is testing exactly this distinction.
Why Chaubatia
India designates certain stations as Foreign Training Nodes — permanent facilities with ranges, accommodation and training infrastructure dedicated to hosting foreign contingents for bilateral exercises.
The reason to build them is practical. Exercising with a foreign army inside an operational formation's area means diverting a unit that has a task, opening a sensitive area to visiting troops, and absorbing the administrative load of hosting. A dedicated node supplies the terrain and the facilities while leaving deployed forces undisturbed.
Chaubatia sits in the Kumaon hills of Almora district, Uttarakhand. It offers genuine mountain terrain — slope, altitude, broken ground, weather — without the political sensitivity or the logistic burden of a forward area along the Line of Actual Control. For a mountain-warfare exercise that is close to ideal: the training value of the Himalaya with none of the complications of the frontier.
Why a desert army comes to the Himalaya
This is the obvious question, and there are three answers.
The UAE has mountains. The Hajar range runs down its eastern edge into Oman, rising well above 1,500 metres, and the Emirati contingent came from a Mountain Infantry Battalion because that capability already exists and needs developing. The exercise is not teaching the UAE Army a terrain it will never see.
Mountain skills are expeditionary currency. A small, well-equipped army that may operate within regional coalitions needs competence across terrain types rather than mastery of one. Desert proficiency is assumed; mountain proficiency has to be acquired, and it can only be acquired in mountains.
And India is the place to acquire it. No army in the world has India's institutional depth in high-altitude and mountain operations — Siachen, the Line of Actual Control, the Line of Control, and a training establishment built around them over six decades.
That last point reframes the exercise. In most of India's bilateral exercises with technologically advanced militaries, India is learning at least as much as it teaches. In mountain warfare the relationship inverts: India is the instructor. This is already visible in the pattern of Indian hosting — high-altitude phases of Yudh Abhyas with the United States at Auli being the clearest example. Mountain warfare is the one domain where India exports training rather than importing it, and that is a distinct and underrated instrument of defence diplomacy: it costs almost nothing, it cannot be sanctioned, and it creates professional relationships that outlast equipment contracts.
The series, and what the terrain tells you
India–UAE army exercises have a short but legible history:
- Desert Cyclone, first edition, 1 to 15 January 2024, in Rajasthan. Focus on sub-conventional operations including Fighting in Built-Up Areas (FIBUA) in desert and semi-desert terrain, with drills covering a joint surveillance centre, cordon and search, domination of a built-up area, and heliborne operations.
- Desert Cyclone II, which concluded in Abu Dhabi — the reciprocal edition on the UAE's own ground.
- Mountain Guardian 2026 — a new named exercise in a new terrain.
Read the progression. The two armies trained in desert and semi-desert, reciprocated on the Emirati side, and have now moved to mountains. Between them, desert and mountain are the full span of India's own terrain problem: the western front is desert and semi-desert, the northern front is high mountain. A partner army that has trained India in neither is of limited interoperable value; one that has trained in both is a potential participant rather than a visitor.
It also marks the maturing of a relationship whose defence leg is the newest. India and the UAE established a Comprehensive Strategic Partnership in 2017 and a Comprehensive Economic Partnership Agreement in 2022, and bilateral trade has since crossed the $100 billion mark — the economic architecture examined in our piece on the India–UAE high-level investment task force. Military-to-military engagement at this level follows the money rather than leading it, which is the normal sequence.
What they will actually do
The listed activities divide into two halves that are worth separating.
The traditional half: joint planning, tactical drills, firing practices, physical endurance training, rock climbing and obstacle training. These are the irreducible skills of mountain soldiering — moving under load on slope, at altitude, in cold, and still being able to shoot and think at the end of it. Rock climbing in an infantry exercise is not adventure training; it is the means by which a sub-unit reaches ground an enemy believes to be inaccessible, which in mountain warfare is very often the whole plan.
The contemporary half: establishing surveillance grids, drone operations, technology-enabled operations and the exchange of tactics, techniques and procedures.
A surveillance grid means integrating multiple sensors — observation posts, radars, thermal imagers, unmanned aerial vehicles — into one coherent picture over a defined area. In mountains this is genuinely difficult, because ridgelines break line of sight and every fold of ground creates dead space that no single sensor covers. Building a grid in the Himalaya is therefore an exercise in arranging sensors so that their blind spots do not coincide, which is a planning problem before it is an equipment problem.
Drone operations in mountains carry their own physics. Air density falls with altitude, so a rotor generates less lift: payload and endurance both drop exactly where the terrain most demands range. Valley winds funnel and gust unpredictably, and satellite navigation can be degraded in deep valleys where the sky is a narrow strip. These are not reasons not to use drones; they are the reasons mountain drone employment has to be learned separately, and why an exercise would list it as a distinct activity rather than assume it.
This is also what makes Mountain Guardian a 2026 exercise rather than a repeat of something from a decade ago, and it connects directly to the rest of the reform package: the Shaktibaan regiments and Divyastra batteries exist to put drones and loitering munitions into the artillery and surveillance structure that a Bhairav battalion would call upon. Exercising a Bhairav battalion with drones and a surveillance grid is exercising the concept, not just the unit. The same structural logic — bilateral series, graduated terrain, rotating venue — governs India's older army exercises such as Maitree with Thailand.
🔑 Revision block
- Exercise: MOUNTAIN GUARDIAN 2026, India–UAE joint military exercise. 5 to 18 October 2026 at the Foreign Training Node, Chaubatia, Uttarakhand. Focus — mountain warfare.
- Strength: 92 personnel, equal representation from both armies. India from a Bhairav Battalion; UAE from a Mountain Infantry Battalion. Women officers and combatants from both armies in specialist roles.
- Aim: interoperability, mutual understanding and cooperation; exchange of tactics, techniques and procedures.
- Activities: joint planning, tactical drills, firing practices, surveillance grids, drone operations, physical endurance, rock climbing, obstacle training, integrated field exercises.
- Bhairav battalions: announced by COAS General Upendra Dwivedi on Kargil Vijay Diwas, 26 July 2025. About 250 soldiers each; light commando units for rapid strikes and quick border deployment, intended to create shock effect, not deep strategic operations. Five reported operational by October 2025, up to 25 planned by early 2026; first public appearance at the Army Day parade, Jaipur, 15 January 2026.
- The 26 July 2025 package: Rudra all-arms brigades · Bhairav light commando battalions · Shaktibaan artillery regiments with drones and loitering munitions · Divyastra surveillance and loitering-munition batteries.
- Three commando tiers: Ghatak platoon (within an infantry battalion) → Bhairav battalion (formation-level, near the border) → Para (Special Forces) (strategic, deep).
- Foreign Training Node: a dedicated facility for hosting foreign contingents, so exercises do not divert operational formations or open sensitive areas. Chaubatia is in Almora district, Kumaon, Uttarakhand — real mountain terrain without the sensitivity of a forward area.
- Why the UAE: the Hajar range on its eastern edge rises above 1,500 m and it maintains mountain infantry; mountain skill is expeditionary currency; and India has the world's deepest high-altitude operational experience.
- The inversion worth noting: in mountain warfare India is the instructor, not the learner — a form of defence diplomacy that cannot be sanctioned and outlasts equipment contracts.
- The India–UAE army series: Desert Cyclone I, 1-15 January 2024, Rajasthan, sub-conventional operations including FIBUA in desert/semi-desert, with a joint surveillance centre, cordon and search, domination of built-up areas and heliborne operations → Desert Cyclone II, concluded in Abu Dhabi → Mountain Guardian 2026, a new exercise in a new terrain. Desert plus mountain is the full span of India's own terrain problem.
- Relationship frame: Comprehensive Strategic Partnership (2017), CEPA (2022), bilateral trade past $100 billion. The defence leg is the newest.
- Why mountain drones are a separate skill: thinner air cuts rotor lift, so payload and endurance fall with altitude; valley winds gust unpredictably; satellite navigation degrades in deep valleys.
- Why a surveillance grid is hard in mountains: ridgelines break line of sight and every fold of ground creates dead space, so sensors must be sited so their blind spots do not coincide.

→ (d) Short-notice shock action near the border. Deep strategic tasks remain with the Para (Special Forces), and the battalion's own commando platoon is the Ghatak.
Q5. A Foreign Training Node such as Chaubatia exists principally in order to: (a) Host foreign contingents without diverting operational formations or opening sensitive areas (b) Train Indian officers before foreign postings (c) Serve as a mobilisation base for the northern frontier (d) House the Army's high-altitude medical research facility
→ (a) A dedicated facility supplies ranges, accommodation and terrain, leaving deployed forces undisturbed and keeping visiting troops away from sensitive frontier areas.
Q6. The UAE Army fields mountain infantry chiefly because: (a) It trains exclusively in partner countries (b) Its primary operational commitment is in Afghanistan (c) The Hajar range along its eastern edge rises above 1,500 metres (d) Mountain infantry is the UAE's only volunteer formation
→ (c) The Hajar mountains run down the UAE's eastern side into Oman, so the capability has a domestic rationale as well as an expeditionary one.
Q7. The India–UAE army exercise that preceded Mountain Guardian, and its terrain, were: (a) Zayed Talwar, in the Arabian Sea (b) Desert Cyclone, in desert and semi-desert terrain (c) Yudh Abhyas, at high altitude in Uttarakhand (d) Khaan Quest, in Mongolia

Q8. Drone employment in mountainous terrain is treated as a distinct skill mainly because: (a) Drones are prohibited above a specified altitude (b) Mountain units lack trained operators (c) Mountain drones use a different radio spectrum (d) Lower air density reduces rotor lift, cutting payload and endurance, while valley winds and degraded satellite navigation add further constraints
→ (d) The physics changes with altitude: less lift means less payload and shorter endurance precisely where range is most needed, and deep valleys both funnel wind and narrow the view of the sky.
Q9. Establishing a surveillance grid is harder in mountains than on plains because: (a) Ridgelines break line of sight and folds of ground create dead space that no single sensor covers (b) Radar is ineffective below freezing point (c) Thermal imagers cannot be used at altitude (d) Observation posts cannot be supplied by air
→ (a) The planning problem is to site sensors so that their blind spots do not overlap — which is why it is listed as a training activity rather than assumed.
Q10. Mountain warfare is unusual among India's defence engagements in that India: (a) Conducts it only in multinational formats (b) Is predominantly the provider of training rather than the recipient (c) Relies on foreign doctrine publications for it (d) Restricts it to the Line of Control
→ (b) Siachen, the Line of Actual Control and the Line of Control have given India unmatched institutional experience, so in this domain India exports training — a form of defence diplomacy that cannot be sanctioned and that outlasts equipment contracts.
📋 How this gets asked (PYQ pattern)
Joint exercises are examined in four recognisable ways, and only one of them rewards general knowledge.
The first is exercise-to-partner-to-service mapping. Mountain Guardian and Desert Cyclone with the UAE, army; Yudh Abhyas with the United States, army; Maitree with Thailand, army; SLINEX with Sri Lanka, navy; Varuna with France, navy; Khaan Quest multinational in Mongolia. The paper swaps one partner or one service, and nothing but a learnt table saves the mark.
The second is venue and terrain. Chaubatia in Uttarakhand for mountain; Mahajan in Rajasthan for desert; Auli for high altitude. Venue questions are rising in frequency because venue encodes the exercise's purpose.
The third is the new formation names. Rudra, Bhairav, Shaktibaan, Divyastra — four names from one announcement of 26 July 2025, each with a distinct function. Expect a straight matching question, and expect "Bhairav equals special forces" as the distractor.
The fourth, worth most in an interview or a written paper, is the purpose question. Why this partner, in this terrain, now? A strong answer connects the partner's own geography, the terrain's place in India's threat picture, and the sequence of previous editions — rather than reciting the strength and dates.
Preparing for NDA? Keep one table of exercises with four columns — partner, service, venue, terrain — and update it the day a new one is announced. Most exercise questions are table lookups, and the analytical ones reward knowing why the venue was chosen. Build the base with our NDA study material, follow the daily NDA current affairs, and prepare with our faculty in the upcoming Cavalier courses in Delhi.
