4.14.3.WHEN TO USE A VBIED DISRUPTOR OR EXTRACTOR A VBIED disruptor is used when the location of the IED’s power source is known (or can be assessed with a high level of confidence), is accessible to actions in a one or two stage process and can be targeted effectively. VBIED disruptors work on the same principle as normal disruptors, but on a larger scale. This scale is required to defeat variables such as increased distance between disruptor and target, and barriers between the two. The size of the disruptor means that as well as disrupting the IED there will be significant damage to the vehicle. The advantage of the VBIED disruptor is that the MA IEDD operator does not need to search and interact with the vehicle to locate the power source prior to achieving disruption with a standard size disruptor.
ׁ WARNING. VBIED disruptors and extractors are powerful tools and the risk of sympathetic detonation must be considered. The MA IEDD operator should match the disruptor to the target and consider the likely location of detonators and exposed detonating cord. These are sensitive components that are particularly vulnerable to blast pressure and high velocity fragmentation.
VBIED extractors are used when all the components of a VBIED are located together but gaining access for a disruptor is problematic or impossible. Extractors are intended to penetrate the vehicle from the outside with such force that the main charge is extracted from the vehicle.
ׁ HINT. VBIED extractors are an extremely useful tool when VBIED disruptors cannot be used due to the location of an IED’s components in the vehicle.
ׁ WARNING. Although a VBIED extractor will normally separate an IED’s component parts in the extraction process, an MA IEDD operator should consider the risk of the IED remaining intact and take appropriate mitigation measures.
4.14.4.UTILISING VBIED DISRUPTORS AND EXTRACTORS
The preferred way to deploy a VBIED disruptor or extractor is remotely. However, when this is not available, manual deployment can be undertaken.
ׁ WARNING. The MA IEDD operator’s threat assessment MUST identify that the VBIED is a legacy device, not part of an active scenario, before any manual approach to place a disruptor or extractor is performed.
EXAMPLE 1 – IMPROVISED VBIED DISRUPTOR, TWO-STAGE ATTACK
In this example the VBIED consists of an RC pack in the centre console with a wire link to the main charge in the trunk. The main charge consists of two 25-litre containers filled with HME, each with internal detonators. The VBIED disruptor has been made from three commercial 1-litre bottle disruptors, each containing 250 g of commercial high explosive. The bottle disruptors were secured around a wooden pole in a triangular configuration and linked by detonating cord, which runs part-way along the wooden pole.
ׁ HINT. Ensuring the detonating cord runs the length of the pole ensures that the detonator can be easily attached by the MA IEDD operator from outside the vehicle once the disruptor is in position.
