India's armed forces have three wings: the Army (land), the Navy (sea) and the Air Force (air).

Questions students ask

The real ones — pulled from the Q&A community and tutor sessions.

After independence India wanted to judge each world issue on its own merit and focus on its own development, so it chose not to side with either superpower bloc during the Cold War.
