Interesting but not surprising news, Pakistani members inform me the Mi-35s on order(?) are for Special Operations Forces so there is a seperate requirment for a decidated attack helicopter to replace the aged Cobras and since the AH-1Z and T-129 are stuck in the same "pending USG approval" postion the Z-10 seems like a logical option.
I'm not sure if I buy the whole "China needs to have this product battle tested" theory because a) there are many cutting edge military prodcuts out there that are respected and known to be lethal but have never been used in anger and b) Pakistan's COIN operations are hardly "battle testing", going up agaisnt an enemy with no AAW capabilty and who are mostly move around in soft-skinned vehicles, not IFVs/MBTs so it is not like the Z-10 in Pakistani service would really be pushed any further than the PLA could at home in simulated combat exercises.
