Hi Guys,
well am from pakistan, and the destroyed tank pic is of Al-Zarrar tank, employed for the first time in the war on insurgents, as it had better survivability and main reason for its employment was due to its night fighting capability, as in this phase of war in swat, army relied heavily on night operations.
As for this tank, it was destroyed by a huge IED and by the grace of Allah the crew had survived. The area where this tank was destroyed, as by army official recollections, this area saw a very heavy pitched battle, and the troops faced 20+ suicide attacks on this same spot where u see the tank destroyed. The insurgents attack was so heavy that they had to withdraw and the next day brought reinforcements with this tank, which made the insurgents run away.
Crux of the story is that the tanks proved its worth and took hits even by RPGs.
Pakistan had employed these latest tanks for the first time in COIN operations, and with the passage of time and battles they will learn more and make more effective techniques to stop damage to these tanks.
