How to SLLS https://survivormind.wordpress.com/2012/12/05/stay-alert-stay-alive-slls/
Stop – Everyone takes a knee and completely stops moving. Breathing goes shallow. Nothing moves but your head like it’s on a swivel and you move it in a a slow, deliberate motion so that you don’t even hear your neck rub against your collar. Making the smallest noises can literally cancel out the benefits of this entire exercise. You must be absolutely silent. Part of stopping has to do with feeling as well. You will suddenly notice which direction the wind is blowing. You’ll realize you are a little overdressed because the insides of your thighs are sweating. Etc.
Look – You move your head from side to side, up and down, taking in everything around you. You will start to notice things that you didn’t see before, like an odd boot print, a broken twig in front of you when you are the first man in the movement, a distant fighting position on the side of the hill, etc.
Listen – There is absolute silence from those around you. Your hearing will start to key in on faint noises that you couldn’t hear before. You’ll suddenly realize that there is a road somewhere in the distance through the thick copse of trees in front of you. Animals will begin to make noise again. You may hear enemy troops, laughing in the distance.
Smell – Our ability to smell is muted by the comforts of civilization. If you’ve ever been outdoors for more than a few days at a time and been starved, you start to smell things you never would normally. I once conducted SLLS by myself in a patrol base in Ranger School and smelt peanut butter. I was like WTF? It’s not chow time. I began walking around and found the offender on the very opposite side of the patrol base from me, 100 yards away. Yes, I smelt this clown’s peanut butter from 100 yards away. This would never happen in your outdoor cafeteria at your local University. Like I said, our smell is muted. While conducting SLLS out in nature, you’ll notice things that you normally would not. The smell of weapons discharge, fire, food, dead animals or people, and you’ll smell it at a distance you never thought possible.
