Which of the following is/are correctly matched in terms of equivalent rank in the three services of Indian Defence forces?
| Army | Air Force | Navy | |
|---|---|---|---|
| 1. | Brigadier | Air Commodore | Commander |
| 2. | Major General | Air Vice Marshal | Vice Admiral |
| 3. | Major | Squadron Leader | Lieutenant Commander |
| 4. | Lieutenant Colonel | Group Captain | Captain |
Select the correct answer using the code given below:
- A1 and 4
- B1 and 3
- C2, 3 and 4
- D3 only
Show answer
Answer: (D) 3 only
Correct Answer: (d) Only pair 3 is correct.
Let's check each:
Pair 1: Brigadier = Air Commodore = Commander — ✗ WRONG.
Brigadier matches Air Commodore, but the Navy equivalent is Commodore (not Commander).
Pair 2: Major General = Air Vice Marshal = Vice Admiral — ✗ WRONG.
Major General matches Air Vice Marshal, but the Navy equivalent is Rear Admiral (not Vice Admiral).
Pair 3: Major = Squadron Leader = Lieutenant Commander — ✓ CORRECT.
This is the right match across all three services.
Pair 4: Lieutenant Colonel = Group Captain = Captain — ✗ WRONG.
Lieutenant Colonel matches Wing Commander (Air Force) and Commander (Navy).
Memory tip:
This topic requires rote memorization.
Focus on the most commonly tested ranks and learn them in a table format.
Defence rank equivalency is tested to check if students know the basic structure of India's military hierarchy across Army, Navy, and Air Force.
UPSC often includes one or two defence-related questions in Prelims, and rank structure is easier to test objectively than complex military strategies or equipment specifications.
The question tests pure memorization - students must learn the rank equivalency table by heart since there are no logical shortcuts to derive the answers.

Equivalent Ranks Across Army, Navy & Air Force: Complete Hierarchy
Only Major = Squadron Leader = Lieutenant Commander was correctly matched in the question
Navy uses different rank names: Commodore (not Commander), Rear Admiral (not Vice Admiral)
Air Force Wing Commander = Army Lieutenant Colonel = Navy Commander
Brigadier rank exists only in Army and Air Force (Air Commodore), Navy equivalent is Commodore
Why This Matters
The Indian Armed Forces maintain equivalent ranks across services to ensure proper protocol and command structure during joint operations. Each service uses distinct nomenclature reflecting its heritage and operational environment.

Question Analysis
This PYQ tested the most commonly confused rank equivalences. Pair 3 was the only correct match - Major = Squadron Leader = Lieutenant Commander. The other pairs contained typical traps where Navy ranks were incorrectly paired.
Commander (Navy) ≠ Brigadier (Army) - Navy equivalent of Brigadier is Commodore
Vice Admiral (Navy) ≠ Major General (Army) - Navy equivalent of Major General is Rear Admiral
Captain in Navy is much senior (equals Army Colonel) than Captain in Army
Air Force Group Captain = Navy Captain, NOT Army Lieutenant Colonel
Wing Commander is the Air Force equivalent of Army Lieutenant Colonel and Navy Commander
