VT-4 entered in 2021Pakistan has 300 VT4s on order right?
Is this Haider tank the VT4?
This article from 2021 states Al-Khalid II may use VT-4 tech (suggesting it's not a VT-4 itself). Haider MBT may be the same as AKII.
As for the Al-Zarar and Al-Khalid tanks, the Haider MBT (Main Battle Tank) is based on the Chinese . During IDEX 2023, a scale model of the Haider was displayed on the Pavilion of Pakistan. Citing information from a Pakistani manufacturer, the new Haider MBT has been designed using the design of the Chinese VT4.
