Urban Myth?

[Wildman]

The theory is perfect , but in practice - a good FLiR operator discerns both positive and negative returns , the absence of heat is just as much a giveaway as the flare of warmth is.

Most infantry combat clothing is supposedly hard to detect with I.R equipment , its a pity the squaddie inside it isn't.
Personally I would not like to bet my balls on relying on this particular claim to fame.

Top Tip to avoid FLiR - Don't be anywhere near where they're looking for you.

true there's nothing that could b done. if tshtf and it was a gun ship with flir then my best defence would be to blatantly wave them down sos style. threat gone.
