Long Range Acoustical Device Deters Enemies March 28, 2008
The Long Range Acoustical Device is a device that uses high-intensity sounds to deter enemies. It sounds annoying just in this video. It is hard to imagine how awful it would be up close. You can read more about the device on War is Boring on on Wikipedia. The AP says there are 1,000 of these LRADs deployed by the military in Iraq.
