warfare support measures/signals intelligence without significantly degrading the operation of friendly
systems. (JP 3-13.1) See FM 3-38.
electronic probing – (DOD) Intentional radiation designed to be introduced into the devices or systems of
potential enemies for the purpose of learning the functions and operational capabilities of the devices or
systems. (JP 3-13.1) See FM 3-38.
electronic protection – (DOD) Division of electronic warfare involving actions taken to protect personnel,
facilities, and equipment from any effects of friendly or enemy use of the electromagnetic spectrum that
degrade, neutralize, or destroy friendly combat capability. Also called EP. (JP 3-13.1) See FM 3-38,
ATP 3-13.10.
electronic reconnaissance – (DOD) The detection, location, identification, and evaluation of foreign
electromagnetic radiations. (JP 3-13.1) See FM 3-38.
electronics security – (DOD) The protection resulting from all measures designed to deny unauthorized persons
information of value that might be derived from their interception and study of noncommunications
electromagnetic radiations, e.g., radar. (JP 3-13.1) See FM 3-38.
electronic warfare – (DOD) Military action involving the use of electromagnetic and directed energy to control
the electromagnetic spectrum or to attack the enemy. Also called EW. (JP 3-13.1) See FM 3-38, ATP 3-13.10,

electronic warfare reprogramming – (DOD) The deliberate alteration or modification of electronic warfare or
target sensing systems, or the tactics and procedures that employ them, in response to validated changes in
equipment, tactics, or the electromagnetic environment. (JP 3-13.1) See FM 3-38, ATP 3-13.10.
electronic warfare support – (DOD) Division of electronic warfare involving actions tasked by, or under direct
control of, an operational commander to search for, intercept, identify, and locate or localize sources of
intentional and unintentional radiated electromagnetic energy for the purpose of immediate threat
recognition, targeting, planning and conduct of future operations. Also called ES. (JP 3-13.1) See FM 3-38,
ATP 3-13.10.
electro-optical-infrared countermeasure – (DOD) A device or technique employing electro-optical-infrared
materials or technology that is intended to impair the effectiveness of enemy activity, particularly with respect
to precision guided weapons and sensor systems. Also called EO-IR CM. (JP 3-13.1) See FM 3-38.
embarkation – (DOD) The process of putting personnel and/or vehicles and their associated stores and equipment
into ships and/or aircraft. (JP 3-02.1) See FM 4-01.
emergency management – Emergency management, as a subset of incident management and concerns the
coordination and integration of activities that are necessary to build, sustain, and improve the capability to
prepare for, protect against, respond, recover from, or mitigate threatened or actual natural disaster, acts of
terrorism, or other manmade disasters. (FM 3-11)
emergency medical treatment – The immediate application of medical procedures to the wounded, injured, or
sick by specially trained medical personnel. (FM 4-02)
emergency operations center – (DOD) A temporary or permanent facility where the coordination of information
and resources to support domestic incident management activities normally takes place. Also called EOC.
(JP 3-41) See ADRP 3-28.

appropriate joint field office conducting planning and coordination responsibilities in support of civil
authorities. Also called EPLO. (JP 3-28) See ATP 2-91.7.
