Weren’t the yanks working on some sort of “cloaking device” for their tanks? IIRC actively masking the thermal signature of the tank so that instead of looking like a tank it looks like a car?
I wonder how they got past the second law of thermodynamics. Even if they could make the tank look like a hatchback on a thermal imager it would still be like twenty times hotter than any car, and the “masked” portions of the vehicle would still stand out against the background and produce an easily recognisable silhouette.
Coupla things. First, everything above a threshold temp is just white. It can be 100 degrees or 1000, and it's just white. So if you can change the shape of the signature, you don't really make it look "hotter."
Second, this is what our favorite tanks look like through passive IR devices:

You don't want to shoot if you don't know what you're firing at. At the minimum, you give away your position. At worst, you hit a friendly or civilian. This is even more true with an ATGM. You've got one shot, and you just wasted it on some earthmoving equipment, and now the enemy knows exactly where you are. Maybe you just blew up a cheap decoy, and there's an enemy sniper using it to hunt ATGM crews.
