It was also a Democratic counter to the Republicans trying to increase funding for border security What a terrible snipe

So the dude was spying on Russia for Ukraine and they extracted him when the threat got too high? Interesting. Perhaps this was a psy-op posting instead, trying to make higher echelon Russian leadership nervous about potential spies in their ranks.

That, and showing that Ukraine takes care of their assets, going through great lengths to extract people working for them. Examples like these affect the calculus of other potential assets.

Same with the helo pilot a few weeks back - they made a point of announcing that they had ensured the safety of his family too.

Obviously the functionality is a big deal, but how much does it take to hide a soldier from thermal imagers/cameras? Would a really thick coat do it? Or does it actually take some special materials, especially if you want it to be something that isn't A) super visible to the naked eye and B) something you can also move in during tough situations? I guess what I'm asking is how much of this is hype vs how much of this is actually a cool new invention?

PurpleXVI posted:https://twitter.com/KyivPost/status/1709506576472486356 The cloak would be new, an older method was using hot smoke (aka smoke with hot oil mixed in somehow) to obscure thermal imaging. It didn’t necessarily hide you, but it just put out so many heat sources that it was supposed to be hard to ID humans on the other side of it. If there’s a heat source (like a body or an engine), sooner or later that heat has to radiate somewhere. Even if you’re blocking it with something, whatever you’re using to block it will read a little warmer than the other things around it at ambient temp, and thermal imagers can be made ridiculously sensitive. Insulators can buy you some time, and I think I remember a story from early on about the Ukrainians using spray-painted yoga mats as thermal camouflage? Lol maybe they repurposed a survival blanket for someone that’s in hypothermia.

You're probably not going to be able to hide your entire army from thermals, but supposing this is a new or improved capability compared to what they had before, and not just a domestic version of what they've already been provided, it could give infantry infiltrations through the fortified lines at night a better chance of success.

the only way something like this can work is if the heat is being pumped to a radiator or heat sink outside FOV. if that sounds heavy and probably impractical, well, it is.

Apparently the cloak was invented by a retired materials scientist who lived in Bucha. He went back to work to design things for the war effort after he saw what the Russians did to his town.

You're overthinking it, the point is to avoid hotspots. As long as you spread the heat out over a larger area, you are more difficult to detect. Its not like this is untread ground https://en.wikipedia.org/wiki/Multi-spectral_camouflage

They're not trying to hide a sci-fi spaceship against future tech, they're sneaking a few troops past some tired guys in an old BMP or trying to look less interesting to a drone as compared to some feint elsewhere.

Way back when I was tank crew we learned that the ground pad that was part of every soldier's standard kit worked really, really well for hiding body heat from FLIR. Obviously this only works when you're not only stationary but also know from which direction you want to stay hidden so not great for drones and such, but for making it way harder for a platoon of big noisy tanks over yonder to spot your position it can be very effective. A warm coat works to some degree but not super great, where the fabric stretches over joints (shoulders/elbows etc) enough heat leaks out to show up really well and the human brain is fantastic at finding patterns that look somewhat like people. Hiding faces with normal cold weather gear is tough, obviously. There's also the general problem that any garment that significantly limits your personal IR emissions is necessarily going to be very warm which isn't always ideal.

"Hiding your IR emissions" and "keeping you warm" are literally, literally the same thing. No surprise that a ground pad engineered to stop your heat leaking into the ground was very effective at it.

Also, camo like this is already widely in use, and effective, on vehicles. Saab Barracuda is one example.

Yeah, I figured the exciting development would be: something that didn't hinder mobility, something that wasn't super obvious to, say, just a plain glance, and I was wondering if it was something everyone else already had tons of or if this represented an actual advance.

For Foot Mobiles, Camo cloaks have been on the market for at least 5-10 years, with advancements in material and portability. poo poo, even a wool blanket can disperse enough on a person to hide them from many thermals. I follow a lot of military/war adjacent IG, and an active Marine did field testing of various means of hiding from thermals, particularly those on drones, and found that it's a problem is easy to beat with lo tech solutions on small scale and static positions. There are a few companies making specific products, but field solutions include a thermal blanket with a cloth cover with some slight standoff from the heat source. It works for a bit, but the contact points help transpose the heat to the cover. Vehicles is a different beast, but similar solutions help, I would imagine. E- his testing was unscientific and the participants weren't told, so he was using the normal field craft of his unit to evaluate in a natural situation.

The optics on your commercially sourced/Iranian/domestic Russian produced drones will be useful, but they won't be as good as the optics on their tanks, and definitely not as good as what's on the multi million dollar western recon drones. Thermal camouflage solutions that wouldn't work against our hardware might be serviceable against what the Ukrainians are facing.

I got the first generation ones with back in 2011. They were heavy as gently caress, took 4 AA batteries, the thermal was cool but drains your batteries within 15-30 minutes. And we were using the lithium AA with it. The newest ones are lighter and aren't shaped like a brick which is nice. bulletsponge13 posted:The thermals I used at war were updated Gulf War models.

I haven't been on the line for a few years, but yeah the newest stuff are so much more compact than the ones I had during my first deployment. Hell, the 20's (night vision with thermal) are better than the thermals I had for my first deployment and a quarter of it's size.

It basically combined IR, night vision, and augmented reality into one package with the ability to stream UAV feeds and potential to tie in weapon optics. Pretty crazy stuff. The new helmet, Improved Head Protection System, comes with rails purpose built for mounting the system so I think the Army is thinking it's gonna go into full production.
