Distinguish between the Department of Military Affairs and the Department of Defence. How has this bifurcation affected civil-military relations in India?

The Cabinet Committee on Security's decision of 24 December 2019 created the post of Chief of Defence Staff (CDS) in the rank of a four-star General [1], and the Department of Military Affairs (DMA) was carved out on 1 January 2020 as the fifth department of the Ministry of Defence, headed by the CDS as its Secretary [2]. The split reallocated business between a soldier-led and a bureaucrat-led department, marking the deepest change in higher defence management since Independence.

Distinction — mandate and leadership

Effect on civil-military relations

• Uniformed voice inside government: for the first time a military officer sits as Secretary, ending the monopoly of civilian intermediation in Service matters [2].
• Faster, integrated advice: single-point tri-service advice replaces three competing Service submissions [1][3].
• Continuity of civilian control: capital acquisition, budget and policy stay with the Department of Defence, preserving political and civilian primacy [2].
• Frictions persist: overlapping jurisdictions and the slow rollout of Integrated Theatre Commands test coordination between the two departments.
• Institutional deepening: appointment of Lt Gen NS Raja Subramani (Retd) as third CDS in May 2026 shows the office surviving leadership transitions [4].

The bifurcation has thus rebalanced rather than displaced civilian supremacy — professional military judgment now shapes policy at its source, while accountability remains with elected authority. Codifying inter-departmental protocols and delivering theaterisation would convert this structural reform into genuine jointness, fulfilling the Kargil Review Committee's long-pending vision of an integrated national defence.
