Sharpshooter
I've seen the modern version of it in artillery (direct fire mode for the defense of an artillery position) and tank rounds. It ain't pretty, an extremely gross understatement, and it's something you'll never be able to un-see after you've seen what it's done to what used to be combatants in the battle space. You just don't think about it often -- it gets compartmentalized into a special mental space reserved for such things. The movie about it called it the "Hurt Locker".
Also see "Canister". Think of loading a 12lbr with nails, musket ball and/or chain. Touch off at massed infantry about 30yds.
