Best guess......<span>philosophe i dont really know..</span>
One method,if my understanding is correct, is to attack by surpirse or to kill as many people as possible.
By doing that, the killing of numerous/millions of people, usually end on on planes, buildings... That type of stuff.
They usually do bombing of large areas.
~Hope this helped :)
I honestly have no idea on the answer Anyway thanks for the points
