does it matter if the bombs are bigger or not?

they STILL KILL........

Insurgents Using Bigger, More Lethal Bombs, U.S. Officers Say

.....The explosion that killed 14 marines in Haditha yesterday was powerful
enough to flip the 25-ton amphibious assault vehicle they were riding in, in
keeping with an increasingly deadly trend, American military officers say. In
recent months the roadside bombs favored by insurgents in Iraq have grown
significantly in size and sophistication, the officers say, adding to their
deadliness and defeating efforts to increase troops' safety by adding armor to
vehicles. ...............

..........And what happened in the aftermath
of the July 23 attack provided further cause for alarm. ..........

hey, how about more than 1800 of our service people DEAD and i won't even mention the wounded. now THAT is cause for alarm
