Our paint covers combat vehicles' Thermal and IR signature.You can think of it as the heat signature. Obviously, if a vehicle has a less detectable heat signature it would be less visible to a sensor that homes in on heat. The kind of sensors that are found on an enemy DRONE, UAV or a heat-seeking missile (anti-tank, etc.).

We're defending the people who are inside the Humvees or inside Combat Vehicles or inside the buildings. If they can't be seen, and they can't be sought out by missiles, they can't be hurt.

Something that lessens the heat signature would save lives! 

In the face of highly sophisticated modern detection systems, the need for advanced materials to improve camouflage and concealment of signature of military systems is of paramount importance nowadays.
Consequently, effective concealment improves stealth reconnaissance capability and surprise factor for platforms. Reducing drastically thermal/IR emissions the range at which painted platforms can be detected is also drastically reduced, further disrupting and complicating targeting efforts by enemy surveillance and strike platforms. 

Modern threats require modern countermeasures while the golden rule of survivability still demands not to be seen. It's far better for the warfighter to rely on passive defense layers than being obliged to make use of weapons and active countermeasures.   

Gen. Eric Smith, assistant Commandant of the US Marine Corps referred to the psychological element of fear and uncertainty " You never know when you're being tracked by an eye in the sky that's just waiting for the signal to strike. And you have to drop your signature. If you're seen, either because you radiate, or because you're physically seen, you're targeted almost immediatelly."

Nothing could describe more accurately modern warfare and STEALTH becomes MORE VALUABLE than ever.
