Again, you find a problem where there is none, I didn’t even call the VT-5 bad, it’s just that you lack basic comprehension skills. I said it’s not good for Pakistan because we have no use for it, a proper MBT is more useful for Pakistan. That’s why we buy the VT-4 and make the Al-Khalid-1. Though to be fair, the VT-5 is only average at best itself when it comes to light tanks.
As for your VT-4, it’s criticism was justified, it’s not a good MBT when compared to what else is available in the world apart from maybe in some of it’s C4I and Fire control systems BUT It’s the best by a long margin in the Indo-Pak theatre though, and the best option available for Pakistan.
In fact China doesn’t make any tank that’s comparable to the best of what’s available in the west or Russia, the ZTZ-99A is also average at best. It improves upon firepower and protection a little bit over the VT-4, but falls behind in technology, so it ends up at the same place. but don’t take it from me, I’m far too biased.
