Afghanistan: Could Pakistani drones hit the Panjshir Valley?

Justin Bronk, of the London-based Royal United Services Institute, doubts if they were. He points out that the Chinese-made CH-4 uses a Chinese-operated satellite communications network to pinpoint long-range targets. "The Chinese may be reluctant to facilitate any Pakistani cross-border violations," he says. "In that case, the CH-4 would need a direct line-of-sight radio control link from a ground station, making it extremely difficult - but not impossible - to operate significant distances from the Pakistani border in rugged terrain."
