Yes. Unfortunately many people are reading this thinking it's a FLIR invisibility cloak.

FYI Ukraine already has FLIR invisibility cloaks (fancy camo space blankets): https://www.youtube.com/watch?v=GfdF3iIwoX4

This is thermal cloak, explained here: https://www.youtube.com/watch?v=CM2RJi4mRZ0&t=52s

Notably it only works after the heat flow settles back down to equilibrium. If you're moving, it doesn't work.
