FIELD: military equipment.
SUBSTANCE: method is defined by the fact that, on the surface of the equipment of class "friendly" has a coating, which eliminates the possibility of IR-radiation to the surrounding areas of the equipment of this class in a definite wavelength interval, unlike the equipment of the class "enemy", radiating the surrounding area in this wavelength interval. The party who identifies the equipment class, configures the IR detector, receiving radiation only in the wavelength interval, possibility of radiation is eliminated by coating the equipment, class "friendly". During participation of allies in military operations, its equipment has a coating eliminating the possibility of IR-radiation in the area surrounding the equipment of this class in the wavelength interval unlike the equipment of the classes "friendly" and "enemy", which emit to the surrounding area at this wavelength, and the party configures the second IR detector, receiving radiation only in the wavelength interval, whose capability of radiation excludes the coating of equipment of the class "ally".
EFFECT: possibility of objectively identifying a party, located on land, water or air, in a fraction of a second determine to which side equipment belongs.
