Really? How far do you think you see at night? What range? Give us a number in feet or yards....
If you're in the woods, at night....good luck running very far. You see, there are these things called trees....they can get in your way junior.

If you're in the woods, the only reason the "enemy" will be there is because you're being hunted like a dog. Otherwise a patrol isn't randomly sent out to just walk into the woods for no reason; regardless of what you see on television or on Playstation which is where you seem to have gotten your military training.
This is just one of several things you simply don't understand...Not just combat tactics but simple strategy that is apparent to anyone who gives it more than 5 seconds of thought.
After the first shot, your ass is grass.
