This new series of posters available utilizes the most up-to-date information on the IEDs and components used by ISIS.
Developed by R.C. Gravett, these designs include photography of the real devices as well as detailed hand-drawn sketches.
Each poster is printed on 18″ x 24″ heavy-duty laminated sheets.
“This IED had been very well thought out and well executed. The crush wires are almost invisible on flat concrete, let alone on debris covered surfaces, as each individual pressure bulb looks like a small piece of gravel. The crush wire (each bulb on the crush wire acting as a mini Pressure Plate) is the primary method of functioning this IED but it is backed up by the second, round (Rolling) IED located behind the door. The rolling IED is perched on a pressure release switch and is designed to be rolled off the switch if the door is forced open.”
