Abstract
Abstract An electrically operated military target capable of emitting an infrared signal when an electric current passes therethrough comprises a multiplicty of independent modules, each module corresponding to a thermal cue of a military threat asset. Each module is a unitary, composite, flexible laminate capable of conducting an electric current. Each module is provided with redundant circuitry for connection to a power source. The laminate is covered by a flexible, thermal insulating pad containing a multiplicity of discrete air-containing cells through which the infrared signal can pass. The target is useful for live fire training with thermal sights.
