As idIRt resembles common soil, it provides an undetectable way to guard an illuminate restricted areas, egress routes, caves, engagement areas, dead spaces and safe lanes of travel in military applications.

idIRt is also an extremely effective law enforcement tool. Officials can mark anticipated crime scenes, trespass areas, and even packages of narcotics.
