electro-optical-infrared countermeasure

Any device or technique employing electro-opticalinfrared materials or technology that is intended to impair the effectiveness of enemy activity, particularly with respect to precision guided weapons and sensor systems. Electro-opticalinfrared is the part of the electromagnetic spectrum between the high end of the far infrared and the low end of ultraviolet. Electro-optical-infrared countermeasure may use laser and broadband jammers, smokes/aerosols, signature suppressants, decoys, pyrotechnics/ pyrophorics, high-energy lasers, or directed infrared energy countermeasures. Also called EO-IR CM. (JP 3-13.1)
