On hardstanding paths and inside buildings the majority of the VOIEDs are probably crush wires, although tension (pull) switches may be encountered. This may include ‘come on’ scenarios deliberately targeting patterns that have been observed of clearance personnel by the opposing armed groups. Command IEDs, either command wire or RC, are possibly located at the two main entry points. Failed time IEDs are assessed as unlikely as they would have probably been observed by the caretaker or the UAV.
