Some Ukrainian soldiers sent to learn modern combat techniques in the UK, Spain, Germany or Poland are now feeling disappointed. When faced with an emergency, they sometimes find more help on YouTube.
I know if you're on the cheaper end of the tech spectrum wool blankets offer the same amount of thermal/IR immunity so for individuals it can offer short term cover - until the blanket heatsinks your body heat into it - and collective protection when used as a form of tarp in conjunction with camo netting and other natural camoflage.
Gotta be careful if it gets wet too. If its warm anyways, the extra thermal mass the blanket will take on will reduce its effectiveness if the blanket is touching you.
Though, if its cold enough to freeze water... you could soak a wool blanket, stretch it out, and I bet when it freezes solid it'd be useful.
