Here is a very serious video of a convoy of Hummer's and a suicide truck bomber. Watch closely as the lead truck, a civilian vehicle pulls over as the convey nears him, than BOOM! No sound but you get a very real feeling of the concussion. It is my understanding that this is an Iraqi convey, which does not make it OK, but if that is true I am grateful it was not American boys.
