Which one of the following pairs of Indian military training institute and its location is not correctly matched?

Introduction / Context:
India has several specialised military training institutions that prepare officers and soldiers for different operational environments, from high altitude warfare to air defence and strategic planning. General knowledge questions often test whether candidates can correctly associate these institutes with their locations. This question asks you to identify which pair is not correctly matched, so you must know at least the basic locations of the main institutions listed, rather than only their names or functions.

Given Data / Assumptions:
- Four pairs of institution and location are given. - Army War College is paired with Mhow. - High Altitude Warfare School is paired with Gulmarg. - Army Air Defence College is paired with Pune. - Rashtriya Indian Military College is paired with Dehradun. - Exactly one of these pairs has the wrong location.

Concept / Approach:
The key concept is simple factual recall. The Army War College, a premier training institution for senior army officers, is located at Mhow in Madhya Pradesh. The High Altitude Warfare School, which trains soldiers in mountain and snow warfare, is based at Gulmarg in Jammu and Kashmir. Rashtriya Indian Military College, a feeder institution for the National Defence Academy, is located in Dehradun, Uttarakhand. The Army Air Defence College, however, is not in Pune; it is actually located at Gopalpur in Odisha. So the approach is to verify each pair and single out the mismatch.

Step-by-Step Solution:
Step 1: Confirm that Army War College is in Mhow. This is a well known fact and the pair is correct. Step 2: Confirm that High Altitude Warfare School is in Gulmarg, a high altitude region suitable for mountain warfare training, so this pair is also correct. Step 3: Recall that Rashtriya Indian Military College is in Dehradun, which is correct and has historic links to officer training. Step 4: Check the remaining pair. Army Air Defence College is actually situated in Gopalpur in the state of Odisha, not in Pune. Step 5: Therefore, the incorrect pair is "Army Air Defence College : Pune".

Verification / Alternative check:
You can cross check using your knowledge of regional clusters: Dehradun is famous for a number of military and training institutions including the Indian Military Academy and Rashtriya Indian Military College. Gulmarg is naturally suited for high altitude warfare training. Mhow has long been associated with higher command and staff training. Pune is known for institutions like the National Defence Academy and some air force establishments, not the Army Air Defence College. This pattern supports the conclusion that the Pune pairing is the odd one out.

Why Other Options Are Wrong:
Army War College : Mhow is correct, because the college is historically and presently located in Mhow in Madhya Pradesh.
High Altitude Warfare School : Gulmarg is correct; Gulmarg's terrain and climate make it the ideal location for this specialised training facility.
Rashtriya Indian Military College : Dehradun is correct, as Dehradun is the long standing home of RIMC and related military institutions.

Common Pitfalls:
A common mistake is to associate every military institution related to officer training with Pune, simply because the National Defence Academy is located there. This over generalisation leads some candidates to accept "Army Air Defence College : Pune" as correct. Another pitfall is confusing different training establishments that have similar sounding names or overlapping functions. Careful revision of the locations of key academies and colleges before the exam largely eliminates these errors.

Final Answer:
The pair that is not correctly matched is Army Air Defence College : Pune.
