India-US Yudh Abhyas 2026 Begins at Auli and Mahajan With Focus on Integrated Battle Groups and Drone Warfare

The armies of India and the United States have begun the 22nd edition of Exercise Yudh Abhyas, with the bilateral military exercise being conducted simultaneously at Auli in Uttarakhand and the Mahajan Field Firing Range in Rajasthan.

The opening ceremony was held at the Auli Foreign Training Node on September 15, bringing together approximately 1,200 troops, with India and the United States contributing around 600 personnel each. Major General Amaresh Gunjan, General Officer Commanding, 14 Infantry Division, and Colonel Benjamin Jackman, Commander of the US Army’s 1st Infantry Brigade Combat Team, 11th Airborne Division, addressed the participating contingents.

This year’s exercise places particular emphasis on preparing the two armies to operate together in mountainous and semi-mountainous terrain while integrating infantry formations with surveillance systems, autonomous platforms and contemporary battlefield technologies.

Integrated Battle Groups at the Centre of Training

A major objective of Yudh Abhyas 2026 is to improve the ability of both armies to employ Integrated Battle Groups in mountainous and semi-mountainous environments.

The training will focus predominantly on infantry-led operations, with troops practising the coordination, planning and execution required for combined military missions across difficult terrain.

Integrated Battle Groups are intended to bring different combat and support capabilities together into more responsive operational formations. Training Indian and American troops within such a framework allows both sides to understand how their respective command structures, tactical procedures and battlefield systems can function together during complex operations.

The exercise is therefore not limited to basic infantry drills. It is designed to improve joint planning, battlefield coordination and the ability of commanders and troops from both armies to operate within a common tactical environment.

Auli Provides Mountain Warfare Environment

The choice of Auli in Uttarakhand gives the exercise a demanding mountain warfare component.

Operating in mountainous terrain places very different demands on troops compared with operations on plains. Movement becomes more difficult, lines of sight are restricted by terrain, communications can be complicated and troops must operate under changing weather and altitude conditions.

Such environments also increase the importance of reconnaissance, small-unit coordination and accurate battlefield awareness. The mountain component of Yudh Abhyas consequently provides both armies with an opportunity to exchange operational experience and refine tactics suited to terrain where mobility and logistics can become as important as firepower.

The Indian Army possesses extensive operational experience in high-altitude and mountainous environments, while the US Army brings its own experience in expeditionary operations and integrated battlefield systems. Yudh Abhyas provides a structured environment in which those experiences can be exchanged.

Drones and Autonomous Systems Become Key Training Element

Technology infusion is one of the central themes of Yudh Abhyas 2026.

According to the Ministry of Defence, the training programme includes the employment of drones and autonomous systems for surveillance and reconnaissance. Their inclusion reflects the increasing importance of unmanned platforms in contemporary land warfare.

Small unmanned aircraft can provide infantry commanders with near-real-time information about terrain, troop movements and potential threats beyond the immediate line of sight. Autonomous systems can similarly expand reconnaissance coverage while reducing the need to expose personnel in potentially dangerous areas.

The exercise will allow troops from both countries to examine how such systems can be incorporated into conventional infantry operations rather than treating drones as stand-alone assets.

This integration has become increasingly important as battlefield surveillance moves closer to individual formations. Infantry units capable of receiving aerial reconnaissance directly can react more quickly, adjust manoeuvres and coordinate supporting weapons with considerably greater situational awareness.

Contemporary Weapon Systems to Be Demonstrated at Mahajan

The Mahajan Field Firing Range in Rajasthan will provide the setting for another major component of the exercise.

Contemporary weapon systems will be demonstrated at the range, allowing participating troops to observe the capabilities and employment concepts associated with modern battlefield equipment.

Conducting parts of the exercise at both Auli and Mahajan gives Yudh Abhyas two distinct operational environments. While Auli provides mountainous terrain for infantry-dominated manoeuvres, Mahajan offers the space required for larger-scale weapon demonstrations, firing activities and technology-focused training.

The arrangement also allows the two armies to examine how similar formations and technologies can be employed under very different terrain conditions.

Multi-Domain Warfare Enters the Discussion

Yudh Abhyas 2026 will also extend beyond field manoeuvres.

Subject Matter Experts from the Indian and US armies are scheduled to exchange views on emerging technologies and developments in multi-domain warfare, bringing a wider operational dimension to the exercise.

Modern military operations increasingly require land forces to function within a battlespace influenced by unmanned aircraft, electronic systems, communications networks, long-range surveillance and other technology-driven capabilities.

The exchange between specialists therefore provides the two armies with an opportunity to compare their approaches to emerging battlefield technologies and examine how new systems can be integrated into existing formations and command structures.

Building Interoperability Between Indian and US Armies

Interoperability remains one of the principal objectives of Yudh Abhyas.

The exercise allows Indian and American troops to exchange tactics, techniques and procedures, while commanders gain experience in joint planning and the coordination of operations involving forces that use different equipment, organisational structures and operational doctrines.

Such familiarity becomes particularly important when forces from different countries are required to operate together. Understanding another army’s communications procedures, tactical decision-making and operational methods can significantly reduce coordination difficulties during combined missions.

Yudh Abhyas has consequently evolved into an important platform for sustained army-to-army engagement between India and the United States.

The 2026 edition demonstrates how the exercise itself is adapting to changes in warfare. Infantry operations remain at its core, but drones, autonomous reconnaissance systems, emerging technologies and multi-domain concepts are increasingly becoming part of the training environment.

By combining mountain warfare at Auli with technology and weapon-system training at Mahajan, Yudh Abhyas 2026 is bringing traditional infantry skills and emerging battlefield technologies into the same operational framework, reflecting the changing character of modern land warfare.
