IED Clearance Good Practice Guide

CAPABILITY

The armed group has a wide range of IED capabilities, including mechanical, electronic and igniferous time-initiated devices. The photograph provided by the caretaker indicates that the armed group has selected a mechanical switch (cooking timer) that has been modified by attaching two metal nails as electrical contacts. The main charge contains approximately 200 kg of HME.

In addition, the armed group has a wide range of VOIEDs, although sensors such as PIRs have not been encountered.

OPPORTUNITY

The armed group has an understanding of structural engineering and construction methods. They have identified a crucial structural pillar inside the hospital that, if destroyed, would result in large-scale structural failure of the facility. They have selected a blast-effect main charge that will strip the concrete from the reinforcing bars inside the pillar, causing collapse.

THREAT SUMMARY

Probable failed mechanical time IED placed to destroy critical infrastructure. Possible anti-lift and secondary VOIEDs cannot be discounted but there is no direct evidence at this stage that anti-lift is present. Further IEDs are also assessed as unlikely due to the extensive activities of the hospital staff inside the building.
