The Invisible Iraq War

Wired has a great write up on a really cool secret technology that was used extensively during the war in Iraq.

In the early years of the Iraq war, the U.S. military developed a technology so secret that soldiers would refuse to acknowledge its existence, and reporters mentioning the gear were promptly escorted out of the country. That equipment – a radio-frequency jammer – was upgraded several times, and eventually robbed the Iraq insurgency of its most potent weapon, the remote-controlled bomb. But the dark veil surrounding the jammers remained largely intact, even after the Pentagon bought more than 50,000 units at a cost of over $17 billion.
