VT 4 base armour same as T 72M1? I highly doubt that. Only ERA can save T 72 but at this point. Which this upgrade probably will.No. As far as can be reasonably estimated from their public info, the gun/armour of their tanks are same old T-72 level.
But due to recent upgrades Chinky-Pakis have advantages in sights & sensors over Indian T-90 that hasn't seen any modernisation since 2007 (welded turret introduced), as well as T/W... Ajeya Mark2 is expected to leave the Bhishma behind.
