I read an article today it said in part:
"The Buffalo — more than 20 tons of armor and protective glass — climbed a ramp to the overpass, where Spc. Johnnie Perkins extended the vehicle’s robotic arm to tear the sign loose from the rope lashing it to the bridge.
Once on the highway below, Perkins poked the arm’s long metal claw through the signs plastic cover, shook things around a bit … and revealed a 155mm artillery shell, the Iraqi insurgent’s improvised explosive of choice."
So my questions are, is an explosion overhead more or less dangerous than one you ride over all other things being equal. Also does 155mm shell mean its 155mm in lenght?
Thank you !
