Bombings
As a consequence of globalisation, the relative ease of access to the chemicals used to make explosives has made improvised explosive devices increasingly prominent. This has the dual effect of increasing the available firepower of terrorists who are generally far weaker than their targets as well as assuring the publicity necessary to attract sympathisers to their cause.
These may be implanted in automobiles to make a car bomb, planted on the roadside to detonate near target vehicles, or even strapped to the bodies of individuals for suicide attacks. From a tactical perspective, each of these methods have positives and drawback, for instance car bombs act as their own delivery mechanisms and can carry a relatively large amount of explosives with weights of up to and over 1000 pounds (450 kg), while a suicide vest has a much smaller payload but may allow the wearer access to spaces and individuals that vehicles cannot.
