What was that Owen Wilson movie that came out a few years ago - was it "Behind Enemy Lines"? I'm not sure. Anyway, there is this scene where he has been shotdown and is trying to escape and evade and I forget why, but he is running through this busted up factory complex when he runs into a minefield of bouncing betty mines. He runs through the minefield flat out, hitting all the trip wires and setting the mines off behind him. It's a great scene, with lots of explosions going off and stuff.
Yeah, like you can really outrun shrapnel, and bouncing betties have a really focused blast whereby all the shrapnel goes behind you instead of being spread out all over the place. Either that, or mines and bombs and artillery shells only kill you if they land right on top of you, because all that they consist of is a bit of flame and smoke.
It has been a long time since I got to fiddle with dummy claymore mines, but I always wanted to know what the shrubbery would look like after hitting the clacker a few times.
I think this powerpoint presentation provides a good answer. Don't mess with the ball bearings!
