This new series of posters available from MAC 7 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.
"ISIS/ISIL has continuously searched for new remote means of initiating their RC IED’s and with the availability of modern cell phone networks and the vast coverage these networks have, it was inconceivable that ISIS would not make use of these facilities. ISIS designed and developed a PCB system to ensure that only their signals could fire the IED when it was required. This was achieved by the production of some fairly simple but ingenious Printed Circuit Boards (PCB’s) designed to filter the received signals between the phone and the IED itself."
