- 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
- Electro-optical MASINT : A subdiscipline of measurement and signature intelligence (MASINT), which has similarities to but complements imagery intelligence (IMINT); it does not form images, but validates them and produces information on phenomena that emit, absorb, or reflect electromagnetic energy in the infrared, visible light, or ultraviolet spectra, where the value is knowledge of the type of energy detected
- Radar warning receiver : allows detection of a radar that potentially might be able to sense the platform carrying the receiver, but does not give detailed characterization of the radar signal, as needed for electronic intelligence.
- United States Special Operations Command : A U.S. Unified Combatant Command with both functional and operational responsibilities, both to prepare special operations forces for the geographic commands, and to execute strategic special operations, typically under national orders and high security classification
