Parachuted from planes, the acoustic sensors become caught in trees where they pick up "enemy" conversations. Seismic sensors--disguised as tropical plants and animal droppings--detect ground vibrations caused by human movement. The information from both types of sensors is relayed to the central computer in Thailand, where it is used to determine bombing targets. (Although "people sniffers...
