Just for the sake of bringing it up, say the S has aleready HTF, you and yours (or just you) are bugged out and have a temporary or permanent camp up in the mountains. One morning you or you and a buddy go out hunting with the intention of hauling a deer back to camp and having a SHTF potluck dinner. Then you hear faint voices off in the disatnce. Upon investigating you see 3 men, all like you, have rifles. Right now they are standing around talking, you don't know if there are more in the area. What do you do to determine if they are a threat?
