Abstract
To provide a combat identification device not affected by adverse environtal conditions, thermoelectric modules are incorporated to a rotatable panel coupled to a target vehicle. By supplying the appropriate power to the thermoelectric modules, one surface of each thermoelectric module would exhibit coolness while the other surface of the module would exhibit heat. The panel to which the thermoelectric modules are incorporated therefore has a cold surface and a hot surface. And by rotating the panel, an identification signature is provided to an infra-red reviewer of an attacker to indicate that the vehicle to which the assembly of the instant invention is attached is a friendly vehicle. Instead of a single panel, two panels may be joined together in an inverted-V shape.
