I've personnally seen worse before. From U.S. knuckleheads at that. All I can say is thank goodness for the blast walls and "dummy pits". I for once learned to not spurn what I before looked at as excessive safety measures on a range! And refused from that point forward to be anywhere near cooks with ordanence.
A huge problem with Afghanis is that the men didn't grow up with sports the way we (at least Americans) did, so, while they can run your ass off hiking through mountains above 10K feet, they're hopeless with things as simple as jumping jacks or throwing a ball. They can't do jumping jacks to save their life, and they throw like girls.
