PA 25th mechanized Division crosses Longewala and gets closer to Ramgarh. India drops paratroopers behind 25th mechanized Divs advance, between Longewala and Ramgarh, avoiding 25th Mechanized Div's SAM cover. PAF is a no show to cover 25th Mechanized Division in Indian skies. Not only is the supply cut for PA forces but it gets encircled from all sides.E
It's just not a viable option anymore IMHO the modern battlefield is very hard for mass troops drops.
This is a very basic scenario. There can be many more.
