you'll call in enemies, and be out of ammo in a week, no matter HOW much ammo you THINK you've got stockpiled. You won't know if it's a skunk, a guy crawling, or a guy walking. So where do you AIM, hmmm? Even if you do know the general area he's in, do you figure on him being standing? If you do, and he's crawling, you fire over his head. If you aim 6" above what you THINK is "ground level", and dont hit his ankle, he'll dive off to one side, behind a tree, and then YOUR blasts and flashes let him fire his blastless and flashless rds ACCURATELY at you. Even in the daylight, it doesn't take a lot of brush to hide a guy, to hide a stump or stone or gully that provides him with PERFECT cover, while you waste all your ammo firing at what you can't see. You focus on him all day long, and somebody that your noise "called in" will shoot you in the back, like the idiot that you are. Brush deflects lots of bullets, including 45-70 and 308, and at your first shot, he's either diving prone, or running-diving for cover. So if your first shot aint a solid hit, you will be most unlikely to hit him, except by luck, and now he knows of you, and probably knows your location, too.
