with subsonic ammo, with breech blocked shut. Some might be dumb enough to shoot the standing man, but I'd put a bullet into all the prone men's heads that I could, if silence was essential. They dn't make as much noise from falling down as does the standing guy. Once hit all those, hit the sentry, then put a bullet into as many more sleeping-bags as possible. See, you pussies can't imagine doing anything but fleeing from a group of pursuers, but I aint a wimp like you are.
