India's defence establishment entered a new chapter on Sunday as General N.S. Raja Subramani assumed charge as the country's third Chief of Defence Staff (Chief of Defence Staff (CDS) Explained by Drishti IAS.) Taking over from General Anil Chauhan, the new CDS (Ministry of Defence, Government of India) outlined his vision for strengthening national security through defence modernization, indigenous military capabilities, and the implementation of the long-awaited theatre command system aimed at improving coordination among the Indian Army, Navy, and Air Force.
After taking charge, General Subramani emphasized that the Indian Armed Forces, the Ministry of Defence, and all associated institutions are working in complete coordination to strengthen national security and safeguard the country's interests.
He stated that efforts would be intensified to modernize the armed forces through the induction, procurement, and deployment of indigenous defence equipment and advanced military technologies. He also stressed the need for innovative strategies and modern operational approaches to enhance combat readiness.
Focus on Theatre Command Reforms
One of the most significant challenges before the new CDS is the implementation of the integrated theatre command system. The reform aims to create unified command structures for better coordination among the Army, Navy, and Air Force.
A day before General Subramani assumed office, Army Chief General Upendra Dwivedi had indicated that the theatre command initiative was progressing steadily. According to him, a comprehensive report has already been submitted to the Defence Minister and is undergoing examination at multiple levels.
General Dwivedi expressed confidence that the new command structure could become operational within the next two to three years, provided the strategic interests of all three services are carefully balanced.
At present, India's armed forces operate through 17 separate commands spread across the Army, Navy, and Air Force. Although the three services cooperate during joint operations, each functions under its own independent command hierarchy.
The theatre command model seeks to replace this arrangement by establishing a unified commander responsible for a specific geographical area or operational objective, enabling all three services to function under a single leadership structure.
Military Career and Educational Background
General Subramani was commissioned into the Indian Army in December 1985 through the Garhwal Rifles Regiment.
He received his foundational military training at the National Defence Academy (NDA) and later attended the Joint Services Command and Staff College in Bracknell, United Kingdom.
Following his return to India, he served as Brigade Major in a Mountain Brigade and subsequently pursued higher strategic studies at the National Defence College in New Delhi.
Academically, he holds a Master of Arts degree from King's College London and an MPhil in Defence Studies from the University of Madras.
Distinguished Service Spanning Four Decades
General Subramani's military career extends over nearly 40 years and includes several key operational and leadership appointments.
In 2025, he served as Military Adviser in the National Security Council Secretariat. Prior to becoming CDS, he held the post of Vice Chief of Army Staff from July 2024 until July 2025.
His command experience includes leading the 168 Infantry Brigade in Samba, Jammu and Kashmir. He also served as Chief Instructor at the Defence Services Staff College in Wellington.
Throughout his career, he has been honoured with several prestigious military decorations, including the Param Vishisht Seva Medal (PVSM), Ati Vishisht Seva Medal (AVSM), Sena Medal (SM), and Vishisht Seva Medal (VSM).
Understanding the Role of the Chief of Defence Staff
The Chief of Defence Staff serves as the senior-most military officer in India and is responsible for facilitating coordination among the Army, Navy, and Air Force. The position carries a four-star rank.
The CDS functions as the Permanent Chairman of the Chiefs of Staff Committee (CoSC) and heads the Department of Military Affairs (DMA) under the Ministry of Defence.
The office was created in December 2019 with the objective of enhancing jointness among the three services, improving defence planning, and accelerating military decision-making. The late Bipin Rawat became India's first CDS in January 2020.
The CDS provides strategic military advice to the government, oversees coordination in defence acquisitions and logistics, and plays an important role in joint operations, cyber warfare, space security, and matters relating to the Nuclear Command Authority.
After General Rawat's tenure, General Anil Chauhan assumed the position in 2022 before handing over charge to General Subramani.
CDS and Service Chiefs: Distinct Responsibilities
While the CDS is the senior-most military adviser, the position does not exercise direct operational command over the Army, Navy, or Air Force.
Operational control remains with the respective chiefs of the three services. The CDS primarily acts as a bridge between the armed forces and the government, ensuring integrated planning and coordination.
Appointments related to military commands within each service continue to be handled by the respective service chiefs based on recommendations approved by the Cabinet Committee on Security (CCS).
Vice Admiral Krishna Swaminathan Takes Over as Navy Chief
Vice Admiral Krishna Swaminathan also assumed office as the new Chief of the Indian Navy on Sunday, succeeding Dinesh Kumar Tripathi.
Before his elevation, he headed the Western Naval Command, one of the Navy's most important operational formations.
Speaking after taking charge, Admiral Swaminathan said the Indian Navy remains committed to modernization and capability enhancement. He noted that naval forces are maintaining a high state of operational readiness to protect national interests and respond effectively to emerging security challenges across the region.
