1. will be a change in the environment (something new on the route that was not there yesterday).
2. The enemy may leave behind visual indicators of an emplaced IED by accident or on purpose (to inform the local population).
3. Vigilant observation for these subtle indicators can increase the likelihood of IED detection by friendly forces before detonation.
4. Examples of possible roadside IED indicators include, but are not limited to:
oUnusual behavior patterns or changes in community patterns, such as noticeably fewer people or vehicles in a normally busy area, open windows, or the absence of women or children.
oVehicles following a convoy for a long distance and then pulling to the roadside.
oPersonnel on overpasses.
oSignals from vehicles or bystanders (flashing headlights).
oPeople videotaping ordinary activities or military actions. Enemies using IEDs often tape their activities for use as recruitment or training tools.
oMetallic objects, such as soda cans and cylinders.
oColors that seem out of place, such as freshly disturbed dirt, concrete that does not match the surrounding areas, colored detonating cord, or other exposed parts of an IED.
oMarkers by the side of the road, such as tires, rock piles, ribbon, or tape that may identify an IED location to the local population or serve as an aiming reference (such as light poles, fronts or ends of guardrails, and road intersections or turns).
oNew or out of place objects in an environment, such as dirt piles, construction, dead animals, or trash.
oGraffiti symbols or writing on buildings.
oSigns that are newly erected or seem out of place.
