SHTF Preparedness: How to Mask Noise and Light Signitures

by Jeremiah Johnson, Ready Nutrition:

This article is an introduction on how to mask the signatures of light and noise that are given off if not controlled. We are talking primarily about a scenario taking place in the forest, but the techniques can also be applied to an urban setting. The tougher one of the two to overcome is the noise; however, each poses a challenge that if not handled can lead to a problem when you wish to remain incognito in the field.

How to Diffuse Light in SHTF Environments

First let’s deal with light. The reason light poses a problem is we need light to see optimally, but in using it at night, the light can be seen by others, giving our position away. Flashlights and any kind of hand-held lantern, battery powered or otherwise are the main problems here. There are a few simple ways to cut down on these signatures, and all of them take practice.

No white lenses with movement: you need to obtain a red lens for your flashlight. This will not defeat NVD’s (night vision devices), but it will cut down on being compromised by the unwanted naked eye considerably.

When using the flashlight, cover it up: preferably a poncho over top of yourself and the flashlight, to perform whatever task you need to accomplish when moving at night, such as checking your position on the map, or fooling with equipment of some kind. Keep that light covered.

Adjust your eyes and learn to move in the dark without a flashlight: this will take some practice, and some people may not have the night vision abilities to perform it, especially those with eye problems. For everyone else, practice makes perfect. Most nights have a little illumination and are not pitch dark (except for the New Moon and a day before and after).

Smokers: you must hide the signature of the end of your cigarette. Through NVD’s it appears to be a flare going off from a distance. Either cup it within your hands, or inside of an aluminum pouch, such as found with MRE’s (Meal Ready to Eat). When you light that cigarette you also tend to give off a big signature. Best thing I can tell you is to quit smoking and really nip it in the bud. Not to mention the fact that you can smell a cigarette from several hundred feet away.

How to Minimize Noise Levels in Dangerous Situations

Noise is an entirely different animal. We make noise as we walk. We can’t help it.

What we can do, however, is control the amount of noise we make…and reduce the amount that would give away our position. You must practice noise discipline in order to perfect it! Looking where you walk and where you take your next step is key. Be keenly observant of where you are moving and through what. Are you facing a large area covered in dry leaves, with dry weather? Are there dried branches and twigs strewn all over the place?

How about sticker bushes and nettles in the summertime? If you’re not crushing them underfoot, how about if one of them whips you across the face? Unless you are prepared to take the pain of it, you may yell, curse, or cry out. You should practice moving through all of these different types of substances. In addition, how about the noise made just as a consequence of your movement?

Many people carry so much stuff, such as keys, change in their pockets, etc., that they mimic a tambourine when they walk. Let’s not forget our happy, singing, laughing, chirping tracking devices…our cell phones. Your cell phones: I don’t use one. You can believe when Uncle Ed tries to reach you or you get a call from Gram-gram, or some other family member, and you’re out in the woods? The whole world (animal, vegetable, and human) will hear that ringtone. Clattering gear that is rattling around, the sounds of trampled branches and vegetation, the occasional grunt in fatigue or pain…all of these will give you away.

Any and all of your rattling gear needs to be silenced. Everything that is loose must be tied down and secured. This is not just prudent: this is survival. “What is the situation?” you may ask.
