The Improvised Explosive Device Countermeasure Equipment (ICE) is a vehicle-mounted electronics-based jamming system that uses low-power radio frequency energy to thwart enemy improvised explosive devices (IEDs). The radio frequency energy it emits blocks the signals broadcast by radio-controlled detonators, such as cell phones and cordless telephones, that would otherwise trigger the hidden IED to explode. ICE was developed by the Army Research Laboratory (ARL) at White Sands Missile Range and the Physical Science Laboratory (PSL) at New Mexico State University in 2004 to counter the rising IED threat in Iraq. Due to the urgent demand for counter-IED equipment, ICE was designed and built within three weeks and was provided to troops in less than six months after the project started.
