So it's like this
2/3 weeks -Build up phase (similar to BUD/S indoc & CD Aptitude)
Then selection starts
Phase 1 Combat Diving Phase 10 weeks - (similar to CD training and BUD/S Dive Phase)
Phase 2 Land & Amphibious Phase 10 weeks - ( think of it like a combo of BUD/S 1st and 3rd Phase)
Phase 3 Special Weapons & Tactics 10-12 weeks - ( includes 3 weeks of Static Line Parachuting in Agra, Jungle warfare, survival course, 4 weeks counter terrorism training (mainly ship and oil rig takedown), basic driving, operating a 2 man chariot and escape and evasion)
After that, those who want to do sniping, got there, MARCOs no longer do CIJW I guess, HAWS maybee yes (prior to Kashmir deployment - part of their pre-deployment workup) and HAHO/HALO yes later on only those who want to or those who do the SDV course)
