Sir are you serious? Who told you this? Indians are establishing a logistic hub for their MKIs with the help of Russia , Which means that they can have whatever they need for their large fleet of Su-30s on their own.
Read carefully Sir I said "Indo-Pak theatre of war", Both India and Pakistan have advance 3rd generation tanks but they can utilize their reserves too if needed to fill operational gaps in a large scale war. It doesn't mean that our reserved Pattons will be going head to head against T-90s.
Well Sir capabilities is not everything, There is a big factor of numbers when you talk about Indo-Pak theatre of war. India possesses couple of hundreds of T-55s in their reserves and so do us.
We have enough APCs I guess but PA is really under equipped when it comes to IFVs. In my opinion we should buy some AMX-10Ps from KSA and upgrade them locally with Bushmaster IV chain guns etc. According to wikipedia Saudi's have 600 of them in reserve.
