Melmoth Thanks for clearing that up.
I think the behaviour of the US as a State, rather neatly mirrors the behaviour of the average US infantry platoon.
Someone fires a couple of shots in their proximity and suddenly the air is filled with 5.56 flying in every direction, and hitting all and sundry-apart from the desired target.
Result?
Ammo expended, no of enemies increased, progress made? Bugger all!
