Regarding the name of army SF and meghdoot
@rkhanna is the man to answer that as he knows Para regtt politics better than me.
The Meghdoot Force was an adhoc unit clobbered together by Major Megh Singh during the 65 war. the Major was a visonary in Asymetrical warfare and followed in the hallowed steps of David Sterling. The Unit was never part of Army orbat
Post war the "unit" was so successful that the special operations capability was deemed neccecary to be built and the Para Regiment was deemed the best place to build the capaInbility as they had the best infra/ schools at the time.
The Meghdoot Force then became 9 Para Commando (now 9 Para-SF) - Major Singh was then the First CO of the Official Unit which was 9 Para-Cdo
in 1986 or so a plan was undertaken to Remove the 3 para-cdo battalions from the Paras and form a Special Forces Regiment. After almost 6/7 years of haggling and infighting the plan was abandoned citing Administrative and logistical issues. To appease the Commando Component the 'Commando' tag was dropped for the Special Forces tag (putting lipstick on a pig) and life goes on.
A large number of the Para Regiment battlefield honors came from SF and the Para powers that be didnt want that to go away in the future. (i.e turf wars driven by personal egos and for personal gain)
And IMO it is due to this "administrative hold" that conventional commanders have over SF that we hardly see them evolve over more than a Commando Role.
Its come to a point today that in the mid 2000s the Conventional Para Co's almost revolted when they didnt get the same Haz pay as SF. They claimed they can and DO do the same job as SF and there is no real difference. To make peace their demands were met
