Hi, in respect of your question,

No, Indian Army doesn't recruit candidates for the PARA SF like Indian Air Force does it for GARUD Commandos. You can only join the PARA SF as an officer once you join the Indian Army.

Selection (encompassing a selection process and basic SF training) - the duration of this stage has changed over the years. For the Para (Air) it was initially 28 days which became 45 days after 1999 and is now 90 days (approximately 3 months).

Thank You.
