India, U.S. armies step up combat interoperability with 22nd Yudh Abhyas

The 22nd edition of Exercise Yudh Abhyas, commenced in 2024, represents a watershed moment in India-U.S. defence cooperation as it witnesses the inaugural participation of the U.S. Army's 3rd Multi-Domain Task Force (3MDTF). This elite formation, headquartered at Joint Base Lewis-McChord, Washington, specializes in synchronizing operations across land, air, cyber, space, and information domains — a capability set that aligns with the evolving character of modern warfare. Historically, Yudh Abhyas began in 2004 as a platoon-level counter-insurgency exercise and has progressively scaled up in complexity, reflecting the trajectory of India-U.S. relations from estranged democracies to "Major Defence Partners" — a designation conferred in 2016 during Prime Minister Narendra Modi's visit to Washington. The inclusion of 3MDTF signals a strategic shift from tactical interoperability to operational and strategic alignment in multi-domain operations (MDO), a concept central to the U.S. Army's 2028 modernization strategy and India's own doctrinal evolution toward integrated theatre commands. Key stakeholders include the Indian Army's Southern Command (host), the U.S. Army Pacific (USARPAC), and the newly integrated 3MDTF, which brings capabilities in long-range precision fires, electronic warfare, space-based ISR (Intelligence, Surveillance, Reconnaissance), and cyber-electromagnetic activities. For India, this exercise enhances readiness for high-intensity conflict scenarios along the Line of Actual Control (LAC) where multi-domain threats — including satellite surveillance, cyber intrusions, and electronic jamming — are increasingly prevalent. Politically, it reinforces the "2+2 Ministerial Dialogue" framework and the Quad's security pillar, while economically, it facilitates defence technology transfer under initiatives like the Defence Technology and Trade Initiative (DTTI) and the U.S.-India Initiative on Critical and Emerging Technologies (iCET). Constitutionally, such exercises derive legitimacy from Article 253 (legislation for giving effect to international agreements) and Article 73 (executive power of the Union extending to matters where Parliament has law-making power), read with the Defence Procurement Procedure (DPP) and the U.S.-India Logistics Exchange Memorandum of Agreement (LEMOA, 2016), Communications Compatibility and Security Agreement (COMCASA, 2018), and Basic Exchange and Cooperation Agreement (BECA, 2020). These foundational agreements enable real-time data sharing, secure communications, and geospatial intelligence exchange — all critical for MDO. Broader themes include India's pursuit of "Atmanirbhar Bharat" in defence through co-development, the strategic imperative of a free and open Indo-Pacific, and the recalibration of non-alignment into multi-alignment. Future implications point toward deeper integration in joint war-gaming, AI-enabled decision support systems, and potential participation of India's upcoming Integrated Theatre Commands in similar multi-domain constructs. As both nations navigate great power competition, Yudh Abhyas 2024 stands not merely as a training event but as a signalling mechanism of convergent strategic intent.
