Some Taliban fighters have been able to ward off attacks by U.S. aircraft by wearing special infrared patches on their shirts that signal that they are friends rather than foes.
The patches, which can also help suicide bombers get close to U.S. targets, are supposed to be the property of the U.S. government alone, but can be easily purchased over the Internet for about $10 each. Also available online: night-vision goggles and military-grade communications systems like the ones used by the terrorists who attacked the Indian city of Mumbai last year.
