Could we defeat thermals with these?

I understand some of you are joking, but from what I’ve seen if you are on fire, and the ground around you is also on fire, you’re basically invisible to thermals. If we could create a similar jacket filled with kerosene, set it ablaze, then poke holes in the bottom and have it drain out flaming liquid, then by running in circles, you could quickly create an inferno in which you’d be invisible within. If we could prime it in some way such that it starts to burn when your chest takes an impact, then it could automatically activate in dangerous zones where you might get hit by shrapnel or have to fall to the ground, thus automatically smokescreening troops.

Watch that clip again anon, it's like 100 feet of travel to the guys up front, that's not three or four seconds of travel if walking, that's like half a minute.
Maybe snow heats up slightly when it's compressed like air does, and the sensor is just that sensitive?

I wonder if snowshoes would work.
>>64914258
But also the depression traps heat like an Igloo since snow isn't conductive, despite feeling cold when it melts. You'd be hard pressed to generate enough heat by compression since work/heat is force multiplied by distance, where the distance is significantly less than it would be for air or some elastic solid for the same amount of force. Maybe there is some friction too as the snow flakes rub passed each other or break.

The snow and air is much colder than the dirt in the ground is.
When you walk through the snow, you disturb the insulating layer, compressing the snow and reducingnits insulating properties. The relative heat from the ground is now visible to the thermal camera.

No, the jacket would be too cold. You'd show up as a jet-black blob on white-hot thermals. Kinda like when US Servicemen in Afghanistan or Iraq would see ghostly apparitions at night through thermal, appearing as people-shaped super-cold spots.

>I had no idea heat would transfer to snow that well.
you don;t need snow even the cheapest thermal picks up foodprints heat easily

The technical term is subnivium, its a little micro-climate between the snow and soil which often stays at around 0deg C despite it being crazy cold above and well below zero.
Lots of little bugs and creatures live in it over winter, so it makes sense ziggers being the unnatural degenerates they are despised by nature and cast out into the cold

With enough beer you can defeat anything.

I wonder if it's because each step compacts the snow, so the slightly warmer heat of your boots/body + the heat of compressed snow(now slush), which is contrasted by the ambient/uniform fallen snow around it.
I was also surprised at first but think about the diff between 8-16° (in American) ambient vs 30-33° boot-slush
Interesting though, not something I'd have thought of in the moment

You want to conceal with the environment and not just prevent your thermal signature to be blocked because you will look like a blob of void temperature that is distinct with the ambient temperature of the environment.

It's not a different in temperature, but a difference in emissivity. Different surfaces at the same temperature can appear differently on thermal imaging, e.g. a rough and a polished block of metal side by side, as they aren't ideal black bodies but act like mirrors to different degrees.
