🧠 Classroom Explanation

The Chief of Defence Staff (CDS) was created in 2019 as part of sweeping defence reforms to enhance jointness and integration among the Army, Navy and Air Force.

The CDS functions as the Secretary, Department of Military Affairs (DMA) in the Ministry of Defence.

🔍 Statement-wise Analysis

Statement 1: Permanent Chairman of the Chiefs of Staff Committee

✅ Correct

The CDS is the Permanent Chairman of the Chiefs of Staff Committee (PC-COSC), ensuring continuity and coordination among the three Services.

Statement 2: Exercise military command over the three Service Chiefs

❌ Incorrect

This is a common prelims trap.

• The CDS does NOT exercise operational or military command over:
  • Chief of Army Staff
  • Chief of Naval Staff
  • Chief of Air Staff

Each Service Chief retains command over their respective force.

The CDS’s role is coordination, integration, and prioritisation, not command.

Statement 3: Principal Military Advisor to the Defence Minister on all tri-service matters

✅ Correct

The CDS is the single-point Principal Military Advisor to the Raksha Mantri on all tri-service issues, replacing the earlier fragmented advisory system.
