If we look at the history of tanks, they are an evolving concept. Instead of just copying the dominant paradigm of the day, perhaps we can think more flexibly.
The Nazi Panzers were some of the most successful vehicles of WW2. yet they would not be rated as an MBT in modern terms. When they were first conceived, there was no equivalent to them. The Germans were willing to think outside the box and come up with an effective solution.
Tanks in the Indian subcontinent need to:
1. Destroy other tanks
2. Destroy softer skinned vehicles
3. Destroy bunkers
4. Provide infantry fire support
The vehicle I've outlined can do all these things and would be far more simpler to manufacture, cost significantly less, and allow mass production easily. In other words, there is a chance, if we all put our minds together and dare to imagine, that such a vehicle could be an asset for Pak armoured forces. Just my 0.02.
