What do you expect, really. There are no specialised instructors in IA, I don't think they even send even 1% of them to friendly foreign countries for training and learn from others. Thats what happens when you try to imitate others but are left out on details.
Small unit tactics are almost non existent in IA doctrine. It's like saying that the poor jawan doesn't matter much, we can always get more chaps out of a billion plus pop. Saala 20 saal se jyada ho gye Kashmir m aur ab jaake ye thoda bhot dyan de rhe h urban combat tactics m, only for RR though.
Just observe the various large exercise video snippets we have been seeing, if you see the movement of tanks and BMPs highly resemble that in the late Soviet exercises. Even the stupid dismounting of Infantry and walking side by side that too at ridiculously small distance in front of enemy positions. I am sure Pak and China have no atgms, RPGs and loitering munitions like really, world has changed their tactics several times over and we are still stuck in 80s.
Agree or not, I think we are going to lose a lot of men in front of PLA which seems to evolve without a stop, trying and adoption strategies from wherever it can.
Over a period of time, the reality I see if particularly IA is grim dark going forward, not like it was particularly better before, maybe in 90s.
