[Robot]

Invisible to the unaided human eye. I was unaware these even existed, until I saw them in a Navy SEAL manual. I guess if you had night vision you could secretly mark your trail, etc.

Did you forget the words , or are they self-evident

Yes, I believe they can be used for marking areas for incoming strafing runs from helicopters, droans, etc.

Used them all the time, but I can see where it would be hard to believe they exist.
