- Introduction to vehicle borne threats
The threats range from vandalism to sophisticated or aggressive attack by determined criminals or terrorists.
- vehicles offer a convenient method to deliver a bomb, known as a vehicle borne improvised explosive device (VBIED)
- a vehicle can also be used as a weapon to injure and kill people, or ram and damage infrastructure
The effects from a VBIED include the blast, fireball, primary & secondary fragmentation and ground shock. Blast stand-off (the distance between the explosive and the asset) is the single most important factor in determining the extent of damage that can be caused. This is site specific; it is important to maximise the blast stand-off distance. Damage to the asset is reduced in proportion to the distance from the explosion.
