The post 1971/IPKF/Op Cactus Indian military actually had some teeth, for the time they were pretty much on par with contemporary forces (leaning more to Soviet standards but also using the bleeding edge Western tech in places) and also had high tempo capabilities
come the 90s and this fell off HARD and they’ve just remained still.
Kargil took the wind out of their sails and exposed a lot of their shortcomings and the mentality has never recovered
obviously not a coincidence that COIN started to occupy more and more of their bandwidth from the late 1980s and that has systematically hollowed them out.
