Need for the Chief of Defence Staff (CDS)

India’s complex security environment marked by a two-front threat, technological warfare, maritime competition, and emerging non-conventional challenges required a single-point military authority capable of integrating the three armed services under a unified strategic framework.

• Absence of Single-Point Military Advice: Earlier, the Army, Navy, and Air Force chiefs independently advised the Defence Minister, often leading to fragmented and inconsistent military recommendations.
• Lack of Jointness Among Armed Forces: The three services functioned through separate operational and administrative structures with limited coordination in logistics, training, communication, and planning.
• Weakness of the Chiefs of Staff Committee (COSC): The COSC operated on a rotational system headed by the seniormost service chief, resulting in lack of continuity, authority, and long-term strategic direction.
• Lessons from the Kargil War: The Kargil War exposed major gaps in intelligence sharing, operational coordination, and higher defence management, strengthening the demand for integrated military leadership.
• Need for Integrated Theatre Commands: Modern warfare requires geography-based and task-based integrated commands instead of isolated service-specific command structures.
• Civil-Military Communication Gap: Service Headquarters functioned largely as “Attached Offices” of the Ministry of Defence, resulting in excessive bureaucratic procedures and delayed decision-making.
• Need for Better Defence Resource Management: Independent budget prioritisation by individual services often led to duplication of expenditure and inefficient allocation of defence resources.
• Growing Nuclear Responsibilities: India’s nuclear doctrine and strategic deterrence architecture required a senior military authority to advise the Nuclear Command Authority on tri-service strategic issues.
• Need to Match Global Military Reforms: Major powers such as the United States, United Kingdom, and China had already established integrated military command systems, making similar reforms necessary for India.
• Rise of New Warfare Domains: Emerging domains such as cyber warfare, space warfare, electronic warfare, and special operations require integrated planning and unified military coordination.
• Need for Integrated Defence Procurement: The absence of a tri-service coordinating authority weakened long-term procurement planning and reduced inter-service prioritisation in defence acquisitions.
• Implementation of Defence Reform Committees: Committees such as the Kargil Review Committee, Group of Ministers Report, and Shekatkar Committee repeatedly emphasised the need for a CDS to modernise India’s defence management system.

Chief of Defence Staff (CDS) Background 

The idea of a single-point military adviser for India’s civilian leadership gained importance after the Kargil War exposed major weaknesses in inter-service coordination and intelligence sharing.

• The Kargil Review Committee (1999) headed by K. Subrahmanyam first recommended a CDS-like integrated military structure.
• The Group of Ministers Report (2001) supported the creation of the CDS to improve military coordination and strategic planning.
• The Integrated Defence Staff (IDS) was established in 2002 as an initial step toward military integration.
• The Shekatkar Committee (2016) again recommended the CDS as part of broader defence reforms.
• In 2019, the Government of India officially created the post of Chief of Defence Staff through a Cabinet decision.
• The CDS post was created along with the Department of Military Affairs (DMA), which functions under as the fifth department within the Ministry of Defence to improve military administration and inter-service coordination.
• General Bipin Rawat became India’s first CDS on 1 January 2020.

• The CDS is appointed by the Appointments Committee of the Cabinet chaired by the Prime Minister.
• The officer can be selected from the Indian Army, Indian Navy, or Indian Air Force.
• The CDS ranks 12th in the Indian order of precedence, equivalent to the three service chiefs.

What the CDS Cannot Do

Although the Chief of Defence Staff is the highest-ranking military adviser in India, the office has important institutional limitations. The CDS was designed primarily as a coordinating and advisory authority rather than an operational military commander.

• No Operational Command Over Armed Forces: The CDS does not directly command the Army, Navy, or Air Force during military operations or wartime situations.
• Service Chiefs Retain Operational Control: The Chief of Army Staff, Chief of Naval Staff, and Chief of Air Staff continue to exercise operational command over their respective services.
• Cannot Issue Independent Combat Orders: The CDS cannot independently deploy troops or conduct military operations without the existing command structures of the three services.
• Limited Role in Defence Procurement: The CDS oversees the revenue expenditure of the armed forces, while capital acquisition and major defence procurement remain under the Defence Secretary and Department of Defence.
• No Absolute Authority Over Theatre Commands: The CDS coordinates and promotes theatre command reforms but does not possess unrestricted command authority over all military formations.
• Primarily an Advisory and Integrative Institution: The office primarily functions as an adviser, coordinator, and integrator rather than a battlefield commander.

• Aligns India with Global Military Practices: The CDS brings India closer to advanced military systems followed by countries such as the United States, United Kingdom, and China that operate integrated defence structures.

Chief of Defence Staff (CDS) Challenges 

Despite being a major defence reform, the CDS institution faces several structural and operational challenges that limit its effectiveness.

• No Operational Command: The CDS does not command the Army, Navy, or Air Force, limiting the role mainly to coordination and advisory functions.
• Ambiguity with Defence Secretary: Overlapping responsibilities between the Department of Military Affairs and Department of Defence create administrative and financial confusion.
• Limited Financial Powers: The CDS controls only the revenue budget, while major procurement and capital acquisition remain under the Defence Secretary.
• Resistance to Theatre Commands: The three services have differing views on integrated theatre commands, slowing military integration reforms.
• Lack of Statutory Backing: The CDS post was created through executive action rather than parliamentary legislation, limiting institutional clarity.
• Inter-Service Rivalries: Differences in organisational culture and operational priorities among the services hinder jointness and integration.
• Absence of National Security Strategy: India still lacks a formal National Security Strategy to guide long-term military planning and theatre command reforms.
