IED Detonation Cat and Mouse

Radio-controlled bombs used to be the biggest killer of American troops in Iraq. Now, they’ve been rendered all-but-useless. Good news, right? Like so much else in Iraq, it’s not quite that simple.
Since the Iraq insurgency began, mobile phones, garage-door openers, and remotely-driven kids’ toys have all been used to trigger improvised explosive devices from afar. In response, the U.S. military has cobbled together an arsenal of radio-frequency jammers, to interrupt the deadly signals before they can set off the bombs. At first, the jammers had all kinds of troubles. Each type of jammer would only cover a relatively small slice of the spectrum. And they’d drive friendly radio and robots haywire.
But those problems have largely been fixed, troops across Iraq report. The newer jammers have effectively killed off radio-controlled IEDs in major chunks of the country.
The explosive cat-and-mouse game continues, though. Read the rest of the article at the link below...
