Terms/ Annex B Exam Ques ons and answers Newest
RATED A+ 2025/2026 NEW!!
Electromagne c Environmental Effects (E3) - Ans The impact of the EME upon the opera onal
capability of military forces, equipment, systems, and pla"orms (Military Standard 464D)
Congested EME test - Ans Tes ng conducted in a congested EME
Contested EME test - Ans Tes ng conducted in a contested EME
Electromagne c A(ack (EA) - Ans Division of electromagne c warfare involving the use of
electromagne c energy, directed energy, or an -radia on weapons to a(ack personnel,
facili es, or equipment with the intent of degrading, neutralizing, or destroying enemy combat
capability. it is considered a form of fires (JP 3-85)
Electromagne c Ba(le Management (EMBM) - Ans The dynamic monitoring, assessing,
planning, and direc ng of opera ons in the electromagne c spectrum in support of the
commander's CONOP (JP 3-85)
Electromagne c Environment (EME) - contested - Ans enemy ac vi es detect, disrupt, exploit,
degrade, deny, deceive, or destroy friendly electromagne c spectrum capabili es for the
purpose of military advantage
Electromagne c Environment (EME) - congested - Ans military and civilian electromagne c
spectrum-dependent systems con nue to crowd the spectrum and increase the amount of
uninten onal interference
, Electromagne c Environment (EME) - constrained - Ans domes c and interna onal
regula ons decrease the amount of spectrum available for military access (JP 3-85)
EMS-Dependent Systems - Ans all electronic systems, subsystems, devices, and equipment
that depend on the use of the spectrum to properly accomplish their func ons without regard
to how they were acquired (e.g. full acquisi on, rapid acquisi on, Joint Concept Technology
Demonstra on) or procured (e.g. commercial off-the-shelf, government off-the-shelf, non-
developmental items).
Electromagne c Spectrum Opera ons (EMSO) - Ans coordinated military ac ons to exploit,
a(ack, protect, and manage the electromagne c environment. Also some mes called joint
EMSO
Electromagne c Protec on (EP) - Ans division of electromagne c warfare involving ac ons
taken to protect personnel, facili es, and equipment from any effects of friendly or enemy use
of the electromagne c spectrum that degrade, neutralize, or destroy friendly combat capability
Electromagne c Support (ES) - Ans division of electromagne c warfare involving ac ons
tasked by, or under direct control or, an opera onal commander to search for, intercept,
iden fy, and locate or localize sources or inten onally and uninten onally radiated
electromagne c energy for the purpose of immediate threat recogni on, targe ng, planning,
and conduct of future opera ons.
Electromagne c Warfare (EW) - Ans Military ac on involving the use of electromagne c and
directed energy to control the electromagne c spectrum or to a(ack the enemy.
(Electromagne c) Spectrum Management (SM) - Ans The opera onal, engineering, and
administra ve procedures to plan and coordinate opera ons within the electromagne c
opera onal environment
