Direct proof of use
Radio-controlled improvised explosive device use in the 2003 Iraq War is documented through U.S. Army and Congressional Research Service reporting on Iraqi insurgent IED attacks and counter-RCIED systems. A 2009 Army report on the new electronic-warfare career field states that Multi-National Corps-Iraq placed electronic-warfare officers with ground combat units in 2006 to counter emerging remote-controlled IED threats.
The triggering methods were described in Army and CRS material as commercial radio or wireless command links. U.S. Army analysis of Iraq and Afghanistan IED strategy described Iraq methods that used long-range cordless telephones or electronic key fobs to transmit arming or firing signals, while CRS reported that U.S. forces disrupted portions of the radio spectrum used by insurgents to trigger IEDs and identified cell phones, satellite phones, and long-range cordless telephones as radio-controlled detonator examples.

Timeline
By 2006, U.S. Army reporting tied Multi-National Corps-Iraq's electronic-warfare response to remote-controlled IED threats in Iraq. The same report described the response as part of a broader Army move to institutionalize electronic warfare for counterinsurgency operations such as Operation Iraqi Freedom.
In 2007, CRS summarized the Iraq and Afghanistan IED problem for Congress and described U.S. countermeasures that jammed radio signals used by insurgents to initiate devices. In 2009, an Army analysis described the Iraq IED campaign as an insurgent weapon system and identified commercial remote-command methods used to arm or fire devices from standoff distance.

Narrative
In Iraq-war use, the documented RCIED role was insurgent command initiation of roadside or emplaced IEDs against coalition and Iraqi-government targets. The Army's tactical analysis presents IEDs as a widely used insurgent weapon in Iraq and explains that command initiation let a triggerman gain distance from the blast while preserving control over timing.
The evidence supports Iraqi insurgent and militia use, not Iraqi government use. CRS described small IED cells in Iraq working for insurgent groups such as al-Qaeda in Iraq or Ansaar al Sunna, with roles that included a bomb maker, emplacer, triggerman, spotter, and sometimes a cameraman. That source also described vehicle-borne IEDs and car bombs striking police stations, markets, and mosques, but the radio-controlled conflict-use claim here is limited to command links used to trigger IEDs.
Counter-RCIED electronic warfare is part of the direct evidence trail because the Army and CRS sources describe it as a response to the Iraq threat. The Army's CREW article says jammers were developed in 2006 when insurgents in Iraq were using cell phones to remotely detonate roadside bombs, and the Duke training article describes remote-controlled IEDs as a common attack form in Iraq and Afghanistan.
