Well that's the neat part, you don't; hardly 10km is what you get.
You're clubbing together multiple issues Buddy
• Are Paras taking bit too much casualties in COIN operations?
Yes and it has multiple issues to it ranging from different training to operating in civilian areas to poor operational planning.
• Are Paras "not that special" anymore?
Yeah, kind of. I always say our Paras are what Ghatak should have been, Ghataks are what RRs should have been, RRs are what infantry should have been and there's none who should have been like Delta Force. MARCOS gives a pretty textbook example of what Special Forces should have been.
• Are we not taking revenge?
We don't know. If it would have an escalation of LSCO with Pakistani soldiers firing artillery and we also replying then it would have been over in days. Almost all the escalations are covert and against the Laws of War so we also retaliate in a just manner. And these are not "civil" enough to be told to the nation in a press conference so no-one knows.
Compare 4x gliders with 8x troops to an utility helicopter carrying a detachment of 8x troops.
I'm starting the comparison for you, you can continue for other parameters like range, speed, altitude if you wish
• A helicopter can have substantial level of armament with it ranging from MGs to missiles.
• Typical sound signature of a 2/4 stroke glider should be around 100dB and for a modern turboshaft helicopter around 115dB.
