Show answer
Answer: (D) 1 and 3 only
Correct Answer: (d) Statements 1 and 3 only.
Statement 1: CDS is the Permanent Chairman of the Chiefs of Staff Committee — ✓ CORRECT.
Statement 2: CDS exercises military command over the three Service Chiefs — ✗ WRONG.
This is a crucial point. The CDS does NOT have military command over the Army, Navy, or Air Force chiefs. The three Service Chiefs retain their independent command.
Statement 3: CDS is the Principal Military Advisor to the Defence Minister on tri-service matters — ✓ CORRECT.
The CDS heads the Department of Military Affairs and advises on joint operations, logistics, and tri-service coordination, but does not command the individual services.
This is a common trap — many students assume CDS means supreme military commander, but that's not the case.
The CDS position was created in 2019 as part of military reforms following the Kargil Review Committee recommendations, making it a relatively new institutional role that UPSC frequently tests.
The key trap is assuming CDS means supreme military commander - in reality, the three Service Chiefs retain independent command while CDS only coordinates and advises on joint matters.
This tests understanding of civil-military relations and the deliberate Indian model where no single military officer commands all three services.

Question Connection
This question tests the common misconception that CDS commands the three Services. Statement 2 is the trap - while CDS coordinates and advises, the Army, Navy, and Air Force Chiefs retain independent command. The CDS role is about integration, not domination.
Trap: CDS has military command over Service Chiefs - WRONG. CDS coordinates but doesn't command
Trap: Confusing CDS with Defence Secretary (civilian head of MoD)
Trap: Thinking CDS controls defence budget - Service Chiefs retain budget authority
Trap: CDS as supreme commander - that role belongs to President of India
