I spent thousands of hours operating various types of FLIR and thermal devices as a Bradley gunner and a .50 gunner in Iraq, and in my experience the answer is pretty obvious: There will always be some contrast of temperature between an object and the background, regardless of how hard you try to mask it. The best strategy is to break up and disguise the outline of your body so your thermal signature isn't recognizable as a human silhouette.

When we were in the U.S. Cav Scouts, we were taught to never brush off dirt and debris from our gear/uniforms while out in the field, because the differences in material helped break up our thermal silhouette. Especially if it was mud. We were also taught to wash our clothes in iodized table salt, as most of the laundry soaps and fabric softeners contain optical brighteners that will light you up under NV.

Like that line, every expensive problem has a cheap solution

[rueporter]

I think many of us freethinkers will need to know how to do this sooner than later. The iron fist is coming down via the state.

These will come in handy when our AI overlords turn up

In the Army I was a 45E E5 (sergeant). That means I was a M1 tank turret mechanic. there is no way to block yourself from its thermal imaging system unless you have a underground bunker. it does 3 types of scans. density, thermal and IR. Now the smaller hand held devices can be fooled. layers of thermal blocking material with an outer layer of ir/thermal absorbing material. Special forces have said clothing. I know this because during training operations we played capture the flag with tanks, helicopters and ground troops. A special forces tried to sneak up on us and was laser tag shot. They then put on their clothes to block all. They made it past all of our troops except the M1 Thermal imaging system and we could hardly see them only their movement gave them away. So again you can fool most systems out there but movement will bust you since any object that moves will change things around it. Even masking your body shape will not work if you have experienced Gunners who know what to look for. @Charles Christianson. See you will have a unique shape and those do not move.

It looks like digging a shallow trench and lying in it with a $2 survival blanket with some bush on top will hide you completely, even from an overhead drone.

In 2010 I was on guard at the from gate of our compound about 30min outside Frontenac in Afghanistan. I was watching these two guys; it looked like they were digging. From nowhere a third appeared. My best guess is that he was simply under a blanket.
A blanket had defeated a quarter million dollar thermal sighting system.

During a training exercise my company was attached to a Abrams Tank Company. During train up the tankers were blowing smoke up our skirts, as usual, about their thermals. Well one of my troops worked for HP manufacturing in quality control. He obtained a couple of bottles of thermal paint, a couple of wooden dowels and two rather large sheets of card board. Well two men got close enough to the tank to humble the crap out of the TC. They, the tankers, had a different view of Infantry and Tanks.

Umbrella. Glue reflective emergency blanket panels to the bottom of it. Drape conventional camo over the top of it and secure to tips of umbrella fan. Wire small, cheap, pinhole "spy camera" through the tip with viewer down to handle.

From there, just stay behind the umbrella and use the camera to keep it pointed at whatever you suspect has IR capabilities. The air acts as an insulator between you and the mylar/aluminum emergency blanket, the conventional cammo over that eliminates any shine risk.

If your umbrella is big enough, you can also literally utilize this system as your hidey hole tent for long duration recon (it's effectively a waterproof lean-to). Pinhole spy cameras also offer the best wide-angle non-distorted multifocal general purpose viewing, while using extremely low amounts of battery (a couple AA's will last for days).

Costs less than most spend on Starbucks for the month, and you can literally fold it up and carry it collapsed on your pack, ready to deploy faster than any other option I've seen.

Might be an idea to make a thermo blocking umbrella. One good enough to hide under. Not only that. It might help in the rain or snow. Light weight and might be a life saver.

Make more videos like this because like it or not dark times are ahead

In my day serving in the Army infantry while being stationed at fort Hood Texas, It's kind of hard to hide from these things while you're on the move or on patrol, but when you are stationary, the best thing to do is to use a camouflage net and dig in making sure that you're using the surrounding environment to camouflage yourself with such as weeds or leaves or tree limbs. This is something that must be maintained at all times. Otherwise you will be pretty easy to see no matter what the enemy is using to search with, the more layers of camouflage you use, the better.

I've heard that if you've been out in the bush for about a month with minimal personal hygiene and are butt naked it'll confuse both night and thermal imaging to the point of rendering them inoperable...not to mention scarring the observer for life thus nullifying them as a further threat 🤣

[metaglypto]

The lesson I learned is, in spite of ANY reduction of heat signature, if you want to be as invisible to IR as possible, stay behind/under the material without touching it, and also camouflage the opposite side with brush/grass/weeds/etc. Clothing does little or nothing.

[niklashall]

I've heard that there are even listening devices that can hear you miles away amongst a noisy rainforest.

[macrofage]

I watched both test videos #1 and #2.
The tent blanket is excellent but the sun window shield is impressive.

[ogsavage]

Aww man - you didn't test the most effective method ever! The "Predator evasion" mud bath method, come on!
Serious note: What natural materials work best to defeat military grade thermal devices?

[pauljs]

If there's enough money backing somebody that really wants to find you, there are also THz near-infrared systems similar to LIDAR that can do density mapping. Those can see through pretty much any light material, and will also make obvious any recently disturbed soil. In a way it's kind of like having an X-ray view, but without the hazards of actual X-ray radiation. Interesting tech that's been around for some years now, but it still seems demonstrations of it are fairly limited.

[JZ]

It seems the ideal solution would be a layer to keep the reflective material off your skin, reflective material, then some sort of conventional camouflage to get rid of the shine and break up your signature.
