A little humint-targeted beacon
that calls a missile from a robot overhead.
How very 21st century.

SLAMABAD, Pakistan – "I was given $122 to drop chips wrapped in cigarette paper at al-Qaida and Taliban houses," confessed 19-year-old Habibur Rehman, just before the Taliban shot him dead for spying for the United States. "If I was successful, I was told, I would be given thousands of dollars," he said.

In a video released last week by the Taliban as a warning to other would-be spies, Rehman recounted how he was recruited to spy on the Taliban in North Waziristan and drop small transmitter chips on specific targets to call in CIA pilotless drone aircraft.
