I really don't think land based infantry doesn't matter much.
Without Air Dominance(Its a Delusion) or Air Deterrence(Its plausible) all infantry talk is meaningless.
You can equip Indian Army with 2000 M1 Abrams, 2000 K-9 Thunder, 3000 Zorawars, 5000 Lynx, 5000 CV90, 10,000 HIMARS, 10,000 Barak-8 Batteries or S-400, at the end of the day they have to first survive the attack of PLAAF. They have to be moved from their bases to battlefield and even before that their fate would already been decided.
A Single Fighter Jet can target any of the land based assets from above but reverse can't be true.
What Iam saying is that until we attain Minimum Credible Air Deterrence or a Certain % Parity with PLAAF, investing in the land based assets is just throwing money into drainage.
