Car-bombs have demonstrated their deadly effects in many attacks
against military and civilian targets in many countries. While a
single suicide bomber can carry a 10 – 15kg of explosives, that will
create a deadly attack against unprotected people, car bombs can carry
several tons of explosives, which can be devastating against large
buildings. Therefore, controlling and denying mobility in the vicinity
of the potential target is of critical importance. Road blocks have
evolved to meet the new challenges of suicide attacks. Modern road
blocks are designed to be transportable, deploy rapidly and absorb
high energy to stop heavier vehicles at higher speeds.
X-Net, designed by Qinetiq is a portable net
constructed from super-strong dyneema polyethylene, with spikes
positioned along its leading edge.
 X-Net is capable of bringing a
vehicle to a complete standstill within 75 meters. X-Net can be used
to secure checkpoints and deny traffic at secured areas, as well as on
pursuit of suspicious vehicles, where opening fire is not an option. A
different system is offered by General Dynamics – the Portable Vehicle
Arresting Barrier comprised of a rapidly erecting net (erected within
two seconds). The net wraps around the target's wheels, bringing it to
a stop within a distance of 35 meters. The system is designed to stop
up to 7 ton vehicles at a speed of 45 mph. Much simpler but highly
effective barrier is the Modular Vehicle Barrier (MVB) offered by
Mifram.
 This lightweight steel structure is quickly assembled into a
highly effective barrier, which stops a vehicle on the spot, with zero
penetration for any sized ramming vehicle. Other devices are using
high power microwave to disrupt vehicle electrical or electronic
systems. |
