The institution of the Chief of Defence Staff is a transformative step in India's Higher Defence Organisation, yet theaterisation remains its unfinished agenda. Discuss.

Recommended by the Kargil Review Committee (1999) and the Naresh Chandra Task Force (2012), the post of Chief of Defence Staff was approved by the Cabinet Committee on Security on 24 December 2019 [1]. It reshaped India's higher defence structure, yet integrated theatre commands — its central purpose — remain pending.

Transformative gains

• Single-point military advice: CDS is Permanent Chairman of the Chiefs of Staff Committee and Principal Military Adviser to the Raksha Mantri on tri-service matters, ending the earlier rotational and part-time arrangement [1].
• Department of Military Affairs: created as the fifth department of the Ministry of Defence, with the CDS as its ex-officio Secretary — for the first time a uniformed officer heads a department, narrowing the civil-military divide [1].
• Legal scaffolding for jointness: the Inter-Services Organisations (Command, Control and Discipline) Act, 2023, notified in 2024 with rules effective 2025, empowers commanders of joint organisations over personnel of all three Services [2].
• Institutional continuity: the office has survived leadership disruption and transition, with the third CDS assuming charge in May 2026 [3].

The unfinished agenda

• No theatre command yet notified: joint planning has advanced, but the proposed theatres remain on paper, so warfighting is still Service-wise.
• Inter-Service divergence: the Air Force's concern over splitting scarce air assets across theatres reflects unresolved doctrinal differences.
• Structural limits: the CDS has no operational command over Service Chiefs, and capital acquisition stays with the Department of Defence, limiting leverage over force structuring [1].
• Executive foundation: the office rests on an amendment to the Allocation of Business Rules, not a statute, leaving design vulnerable to reversal [1].

The CDS has thus altered the architecture of decision-making without yet altering the architecture of war-fighting. Completing the reform requires a phased rollout beginning with one pilot theatre, a joint doctrine ratified by all Services, and integration of acquisition with the theatre commander's requirements. Grounded in political consensus, theaterisation can convert a promising institution into genuine operational jointness.
