From Bovington twitter account:
The Khalid: UK developed, used by Jordan, but designed for Iran. The Islamic Revolution in Iran resulted in the order being cancelled in February 1979. Jordan stepped in and ordered 274.
This version had a CV12 with 1,200HP (close twice of early vehicles) and a TN37 gearbox. OTOH there are no major improvement in gunner's sensors.
But the TC seems to have his own periscope sight with looking at the size maybe a thermal or at least light amplifier installed? Might even run a laser range finder through that.
