Question map
Which of the following is/are correctly matched in terms of equivalent rank in the three services of Indian Defence forces ? 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 :
Explanation
The correct answer is option D (3 only).
Let us examine each statement:
**Statement 1** claims Brigadier = Air Commodore = Commander. However, Brigadier, Commodore, and Air Commodore[1] are equivalent ranks, meaning the Navy equivalent is Commodore, not Commander. This statement is **incorrect**.
**Statement 2** claims Major General = Air Vice Marshal = Vice Admiral. Major General, Air Vice Marshal, and Rear Admiral are equivalent ranks[3], not Vice Admiral. Vice Admiral is equivalent to Lieutenant General. This statement is **incorrect**.
**Statement 3** claims Major = Squadron Leader = Lieutenant Commander. Major, Squadron Leader, and Lieutenant Commander[6] are[4] indeed equivalent ranks across the three services. This statement is **correct**.
**Statement 4** claims Lieutenant Colonel = Group Captain = Captain. Lieutenant Colonel, Wing Commander, and Captain (IN) are equivalent ranks[7], not Group Captain. Group Captain is equivalent to Colonel. This statement is **incorrect**.
Therefore, only statement 3 is correctly matched.

Guest previewThis question is a classic 'CDS crossover'—easy for defence aspirants, a bouncer for pure civilians. It signals that 'Internal Security' (GS3) includes the administrative structure of the forces, not just missiles and exercises. It tests functional literacy of the state apparatus: you know the hierarchy of courts; you must know the hierarchy of the sword.
This question can be broken into the following sub-statements. Tap a statement sentence to jump into its detailed analysis.

Why relevant
Explicitly uses phrasing 'rank of colonel and above in the Army and equivalent posts in the Navy, the Air Force', showing that ranks across services are described in terms of 'equivalent posts'.
How to extend
A student could use this rule to look up where Brigadier and Air Commodore lie relative to 'colonel and above' and then compare the Navy's listed 'equivalent posts' to judge equivalence.

Why relevant
Mentions 'Officers of the rank of Major-General or equivalent rank' indicating official practice of mapping one service's rank to equivalents in others for precedence and protocol.
How to extend
One could extend this by consulting official precedence/appointment lists (which map Major-General to equivalents) and then locate Brigadier/Air Commodore/Commander within that mapped hierarchy.

Why relevant
Similarly cites 'Officers of the rank of Lieutenant General or equivalent rank', reinforcing that multi-service equivalence is used in official lists.
How to extend
A student could apply this pattern to find where Brigadier/Air Commodore/Commander fall relative to Lieutenant General/other ranks to infer equivalence or non-equivalence.
