Many companies have been tapped to supply jammers to coalition forces. forces are dealing with an adaptive, innovative and flexible enemy, according to the Joint Improvised Explosive Device Defeat Organization, or JIEDDO, which is leading the counter-IED effort for the military.Īs insurgents modify their devices to outwit the military, the military in turn adapts its own jamming technologies. Most roadside bombs are remotely detonated using common household devices: cell phones, garage door openers, burglar alarms, key fobs, doorbells, or remote controls for toy cars. "From a simple mortar round on the side of the road with a fuse and a wire running to a push-button, to complex explosives poured into concrete (shaped like curbs) with remote detonators and booby traps." Spencer says IEDs come in a variety of shapes and sizes. "IEDs were always on our minds during every patrol." "We dealt with hundreds of IEDs while in theater," said Spencer. See the casualty toll inflicted by IEDs » From July 2003 to July 2007, 1,565 coalition forces were killed by IEDs, according to. and alllied casualties in Iraq, according to the Department of Defense.
These technologies represent the last line of defense, Marks said. "Ideally what you want to be able to do is have something that can grab very precise signals, capture the signals and render them irrelevant without knocking out your own communication," said CNN military analyst retired Army Brig. However, it also knocks out communications used by U.S. One common method is barrage jamming, which knocks out a broad range of radio signals. Jamming devices, known as Counter Radio Controlled Improvised Explosive Device Electronic Warfare, or CREW systems, attempt to intercept or block a signal before it reaches its intended target, preventing detonation. "There was a definite increase in remote detonation."Ī signal going to a remote-controlled IED operates on a radio or infrared frequency. "The sophistication of IEDs definitely increased during my time in Iraq," said Spencer. The military also uses portable backpack jammers.
Vehicle mounted electronic jammers attempt to block a signal going to a radio-controlled IED. "Any weapon we had against IEDs, was utilized including jamming technology," said Jason Spencer, 29, an Oklahoma City, Oklahoma, engineer who served with the Army in Iraq in 2005.
