Many years ago i had proposed the following.
Merge every ghatak platoon into a ghatak battalion in every regiment. You will have a commando "ranger type" capability at a tactical level - dedicated to their AO. Freeing up SF/Para etc from theater level tactical operations including routine CASO-COIN
Merger the Para Batallions, PBG, - Pathfinders and other parachute units (art / eme/ medics) and certain SFF parachute units into a Parachute Brigade / divison. Along with dedicated Aviation assets- You will have a strategic expedentiary force projection capability. The SFF units will be the dedicated mountain capability of this formation.
Merge The Para-Gurkhas and the Para SF units into A Ranger Regiment type Unit, For strategic Commando Operations. Call it the Special Forces Regiment.
From the above SF Reg create a new selection program to raise a SOF Unit on the lines of the SAS. - don't make selection open to all. Selection only open to The SF regiment. By default you will get older , more experienced and mature candidates.
Do the same with Marcos - expand Marcos create a Marine Cdo Formation - like the British Marines (size and mission) -(with a proper plan for support from naval assets - aviation / support from various other arms - subs, LPDs etc). from there select and create a smaller SBS type strategic SOF unit.
From Garud carve out 3 dedicated units. - CSAR, JTAC and Force security/CT.
Doing the above requires an organizational structure change - not really more money - also requires that each Mil Arm has its own dedicated SOF command. Organizing like that with own unified dedicate procuring, training sub commands will utilise the current money more efficiently.
Put the new army SOF unit, SBS type unit, and selected elements of Garud CSAR and JTAC + a battalion from the SF regiment under a seperate command - give them dedicated air & ISR assets - based on our own ability to fund and actual need. - You will have a dedicated Tier 1 type command ( from an Indian def sense - project power (both soft and hard) in our neighborhood and to SEA and eastern Africa during peacetime)
SG should continues to be the SAD type element of RAW and again should be strategic under the NSA.
