- Electronic warfare : A subset of information operations that deals with the use of electromagnetic or kinetic means to degrade an enemy's military electronics systems, to be able to operate one's own electronics in the face of enemy attacks, and to evade those attacks through protection or deception
- Infrared light : In physics and engineering, a non-visible portion of the electromagnetic spectrum ranging from wavelengths of 750 nm to 1 mm, between the darkest visible red and the shortest submillimeter wave radar
- Laser : Device that produces a very narrow, highly concentrated beam of coherent light, using the principle of amplification of electromagnetic waves by stimulated emission of radiation.
- AVR-2 : A first-and-second generation, obsolescent laser warning receiver
- Chaff (electronic warfare) : A passive, disposable radar countermeasure using strips of metal foil or aluminized plastic, cut to match the wavelength of the expected radar, and used to send false reflections back to the radar receiver
- Cueing : A method by which the output of one or more sensors is used to aim the sensors of another information-gathering or weapons system. These range from helmet-mounted sights in which the pilot's head position aims the targeting sensor on a missile, to sensor fusion where electro-optical sensors aim radars or vice versa.
- ALE-39 : An obsolete dispenser of electronic warfare expendables (e.g., flares and chaff), to be replaced by the AN/ALE-47
- : An electronic warfare expendables dispenser, to be replaced by the AN/ALE-47
- ALE-47 : An intelligent countermeasures dispenser for military aircraft, which can receive commands directly from warning receivers, and dispense expendable radar and infrared decoys, as well as manage a retrievable decoy towed via an fiber optic cable
