Improvised Explosive Device - Detection and Disarmament

Detection and Disarmament

Since these devices are improvised, there are no specific guidelines for explosive ordnance disposal (EOD) personnel to use to positively identify or categorize them. EOD personnel are trained in the rendering safe and disposal of IEDs. The presence of chemical, biological, radiological, or nuclear (CBRN) material in an IED requires additional precautions. As with other missions, the EOD operator provides the area commander with an assessment of the situation and of support needed to complete the mission.

Military forces and law enforcement personnel from around the world have developed a number of render safe procedures (RSP) to deal with IEDs. RSPs may be developed as a result of direct experience with devices or by applied research designed to counter the threat. The supposed effectiveness of IED jamming systems, including vehicle- and personally mounted systems, has caused IED technology to essentially regress to command-wire detonation methods. These are physical connections between the detonator and explosive device and cannot be jammed. However, these types of IEDs are more difficult to emplace quickly, and are more readily detected.

Military forces from India, Canada, United Kingdom, Israel, Spain and the United States are at the forefront of counter-IED efforts, as all have direct experience in dealing with IEDs used against them in conflict or terrorist attacks. From the research and development side, programs such as the new Canadian Unmanned Systems Challenge, will bring students groups together to invent an unmanned device to both locate IEDs and pinpoint the insurgents.

Technological countermeasures are only part of the solution in the effort to defeat IEDs; experience, training, and awareness remain key factors in combating them. For example, there are visual signs that may suggest the presence of an IED, such as recently turned-over soil or sand by a road, or an abandoned vehicle beside a road. Recognizing these telltale signs may be as valuable as having sophisticated detection equipment.
