Exercise Yudh Abhyas?
- Yudh Abhyas is an annual bilateral military exercise between the Indian Army and the United States Army. It provides an opportunity for both forces to train together, improve interoperability and share operational experience.
- The exercise has evolved to cover areas such as high-altitude warfare, field operations, precision fires, command-and-control systems and counter-drone capabilities.
Key Features
The 22nd edition focuses on modern warfare capabilities and joint operational readiness.
1. Participation of Arctic-Trained US Soldiers
- Soldiers from the US Army’s 11th Airborne Division, based at Fort Wainwright, Alaska, are participating in the exercise.
- Their Arctic and cold-weather training is particularly relevant for high-altitude operations in India.
2. Role of 3rd Multi-Domain Task Force
- The 3rd Multi-Domain Task Force (3MDTF) is participating with capabilities related to long-range precision fires and integrated command-and-control systems.
3. First Deployment of MLIDS in India
- The exercise marks the first-of-its-kind deployment of the Mobile Low, Slow, Small Unmanned Aircraft Integrated Defeat System (MLIDS) to India.
- MLIDS is designed to counter threats posed by low, slow and small unmanned aircraft systems, making counter-drone operations an important component of the exercise.
4. Command Post and Field Training
- The exercise includes a Command Post Exercise (CPX) and a Field Training Exercise (FTX). These activities will culminate in a combined live-fire demonstration involving long-range and precision-fire systems.
5. Two-Theatre Format
- Earlier editions of Yudh Abhyas generally focused on a specific type of terrain. However, the 2026 edition is being conducted across desert and high-altitude areas, providing troops with training in different operational environments.
- The first phase is being held at the Mahajan Field Firing Ranges near Bikaner, Rajasthan, where troops are practicing precision and long-range firing.
- The second phase is being conducted at Auli, Uttarakhand, near the Line of Actual Control (LAC), focusing on operations in high-altitude terrain.
Major Components of the Exercise
The 22nd edition of Yudh Abhyas includes:
- Command Post Exercise (CPX)
- Field Training Exercise (FTX)
- Combined live-fire demonstration
- Training with long-range and precision-fire systems
- Integration of advanced command-and-control technologies
The exercise will demonstrate how Indian and US forces can operate together using modern military technologies and integrated systems.
Focus on Counter-Drone Technology
- A major highlight of Yudh Abhyas 2026 is the first-of-its-kind deployment of advanced counter-drone systems to India under the strategic framework of Operation Pathways.
- The exercise will include the Mobile Low, Slow, Small Unmanned Aircraft Integrated Defeat System (MLIDS). This system is designed to counter emerging threats from small unmanned aircraft and drones.
- Its inclusion will help both countries improve their ability to respond to modern battlefield challenges.
Strengthening India-US Defence Cooperation
- US Ambassador to India Sergio Gor highlighted that Yudh Abhyas reflects the growing strength of the India-US defence partnership.
- The exercise provides an opportunity for soldiers from both countries to train together, exchange expertise, build trust, and improve operational capabilities.
- Lieutenant General Joel “JB” Vowell, Deputy Commanding General of US Army Pacific, also emphasised the importance of the exercise in strengthening operational readiness and supporting a free and open Indo-Pacific.
Significance for India
Yudh Abhyas 2026 is important from the perspective of India's defence preparedness because it:
- Enhances interoperability between Indian and US forces.
- Promotes the exchange of military expertise and operational experience.
- Improves preparedness for high-altitude and complex terrain operations.
- Strengthens capabilities against emerging drone and unmanned-system threats.
- Provides exposure to advanced long-range precision-fire and command-and-control technologies.
- Strengthens the broader India-US strategic and defence partnership.
Significance for the Indo-Pacific
- The exercise also has a wider strategic dimension. It supports cooperation between India and the US for maintaining a free, open and secure Indo-Pacific.
- The increasing focus on multi-domain operations, precision fires and unmanned systems reflects the changing nature of modern warfare.
Challenges
- Technological Gaps: Differences in military equipment and technologies can make full interoperability challenging.
- Integration of Advanced Systems: Integrating drones, counter-drone systems, precision fires and advanced command-and-control technologies requires effective coordination.
- High-Altitude Operations: Harsh terrain, extreme cold and low-oxygen conditions make joint operations in high-altitude areas difficult.
- Cyber and Information Security: Protecting sensitive military information and digital systems during joint operations is essential.
- Defence Technology Dependence: India needs to reduce excessive dependence on foreign defence technologies while strengthening indigenous capabilities.
- Emerging Warfare Threats: The growing use of drones, artificial intelligence, cyber warfare and electronic warfare requires continuous adaptation and capability development.
Way Forward
- Enhance Interoperability: Conduct more frequent joint exercises and standardise operational procedures to improve coordination between the two armies.
- Strengthen Defence Technology Cooperation: Promote joint development and co-development of advanced systems, particularly in precision fires, counter-drone technology and electronic warfare.
- Boost Indigenous Capabilities: Use bilateral exercises to gain expertise while strengthening India’s domestic defence manufacturing under Atmanirbhar Bharat.
- Focus on Emerging Technologies: Expand cooperation in artificial intelligence, autonomous systems, cyber warfare, space and multi-domain operations.
- Improve High-Altitude Preparedness: Share expertise in Arctic and high-altitude operations, logistics, survival techniques and specialised equipment.
- Strengthen Indo-Pacific Cooperation: Continue defence engagements that contribute to a free, open, secure and rules-based Indo-Pacific.
- Enhance Information Sharing: Develop secure mechanisms for sharing operational knowledge and intelligence while protecting sensitive information.
India-US Relations
- India and the United States established diplomatic relations in 1947. During the Cold War, relations remained limited because India followed the policy of Non-Alignment, while the US developed close ties with Pakistan.
- After the end of the Cold War, India-US relations gradually improved. The 1998 nuclear tests initially created tensions, but the relationship began to change significantly in the following years.
- A major turning point came with the India-US Civil Nuclear Agreement of 2008, which strengthened strategic and civil nuclear cooperation.
- Since then, cooperation has expanded into defence, trade, technology, space, energy, education and counter-terrorism. The two countries have also strengthened cooperation through platforms such as the Quad and the Indo-Pacific framework.
- Today, India and the US share a Comprehensive Global Strategic Partnership, with growing cooperation on defence, emerging technologies, supply-chain resilience and Indo-Pacific security.
Conclusion
The 22nd edition of Exercise Yudh Abhyas reflects the growing depth of India-US defence cooperation. By combining high-altitude training, long-range precision fires, advanced command systems and counter-drone technologies, the exercise will help both armies improve interoperability and prepare for emerging security challenges.
