Vehicle-borne threats range from vandalism to sophisticated or aggressive attack by determined criminals or terrorists. The mobility and payload capacity of a vehicle offers a convenient delivery mechanism for a large explosive device, although the vehicle itself may be used as a weapon. This section contains guidance that will help practitioners determine the vehicle-borne threat, assess site strengths and vulnerabilities, and identify suitable options for Hostile Vehicle Mitigation (HVM) measures.
Determining the type of vehicle-borne threat being faced
When specifying the nature of the vehicle-borne threat it is important to understand:
- Modus Operandi (MO) – this includes parked, penetrative, encroachment, deception and duress or a combination of attack methods including surreptitious and forcible attack on the barrier with hand tools or explosives
- Threat vehicle(s) – unmodified road vehicles with specific characteristics – mass, speed and structure, as well as vehicle specific capabilities
- Blast effect – especially if considering VBIED attack
