Counter Argument :
Yara we don't have enough sources to full fill domestic production goals, how are we supposed to make AK an MBT ideal for Urban warfare? Our Military forces do not have any experience in this regard as far as utility of MBT is concerned. In mountainous terrain, while dealing with low intensity conflict against militia which lack sophisticated weapon system and rely on their overwhelming Geographical and organizational advantages , we do have a lot experience. We can teach World the tactics, not specific modernization in military hardware.
For example, for Urban Warfare, using MBT against force equipped with ATGMs, installation of Soft Kill as well as Hard Kill Protection System is crucial demand. Along side shells which are specifically meant to kill life in such confined environment (TBX based shells). Neither we have expertise in tank design nor in making of armor for enhanced Ballistic protection.
I believe Israel experience are special in this regard as their threat perceptions include COIN Ops again Hizb ul Allah and Hamas in Lebonan & Gaza strip respectively, and both of these militias are well equipped and trained in anti tank role.
We don't have any such threat perceptions as Tanks in Pakistan are primarily meant to counter India or along side Western Borders to deal with Afghanistan and insurgents (just in case)
