New Delhi: India and the United States are preparing for the 22nd edition of their annual bilateral military exercise Yudh Abhyas, with this year's iteration introducing a significant operational feature — joint training across two vastly different theatres.
The exercise is scheduled to begin in Rajasthan's Mahajan Field Firing Ranges before the participating contingents move to Auli in Uttarakhand, bringing desert and high-altitude Himalayan environments into a single training battlefield. The two-theatre format is being attempted for the first time and is designed to expose troops to fundamentally different operational conditions.
The exercise has evolved considerably since its inception. Originally launched in 2004, Yudh Abhyas has become one of the key pillars of India-US Army cooperation, focusing on interoperability, tactical coordination and the exchange of operational practices. The US Army Pacific sponsors the exercise, which is aimed at strengthening the wider India-US Major Defense Partnership.

The 2026 format carries particular strategic significance because the two phases will expose troops to contrasting battlefield challenges. Rajasthan provides an environment suited to manoeuvre operations and long-range fires, while the Himalayan phase will test troops in conditions defined by altitude, difficult terrain and complex logistics.
For India, such training is relevant to the country's requirement to remain prepared across multiple operational theatres. For the United States, it provides an opportunity to train alongside Indian troops in terrain and conditions that are particularly relevant to India's northern border environment.
Beyond tactical training, Yudh Abhyas also serves as an important instrument of defence diplomacy. Regular exercises allow both militaries to develop common operating procedures, improve interoperability and build familiarity between personnel — capabilities that become increasingly valuable as India and the US deepen their strategic and defence relationship.
The exercise therefore represents more than a routine military drill. Its 2026 two-theatre format reflects an increasing emphasis on multi-environment readiness, interoperability and operational adaptability, while simultaneously reinforcing the broader strategic partnership between New Delhi and Washington.
From deserts of Rajasthan to the Himalayas of north, Yudh Abhyas 2026 will put India-US military interoperability through two very different operational environments.
