The electronic testing method uses branching to select test items based on the answers given while the test is being administered, (TRADOC Pam 350‑70‑2)

electronic warfare                        (DOD) Any military action involving the use of electromagnetic and directed energy to control the electromagnetic spectrum or to attack the enemy. Also called EW.

The three major subdivisions within electronic warfare are‑‑

     a. electronic attack—That division of electronic warfare involving the use of electromagnetic energy, directed energy, or antiradiation weapons to attack personnel, facilities, or equipment with the intent of degrading, neutralizing, or destroying enemy combat capability and is considered a form of fires. Also called EA. EA includes the following:

          1. actions taken to prevent or reduce an enemy's effective use of the electromagnetic spectrum, such as jamming and electromagnetic deception, and

          2. employment of weapons that use either electromagnetic or directed energy as their primary destructive mechanism (lasers, radio frequency weapons, particle beams), or antiradiation weapons.

     b. electronic protection—That division of electronic warfare involving passive and active means taken to protect personnel, facilities, and equipment from any effects of friendly or enemy employment of electronic warfare that degrade, neutralize or destroy friendly combat capability. Also called EP.

     c. electronic warfare support—That 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. Thus, electronic warfare support provides information required for immediate decisions involving electronic warfare operations and other tactical actions such as threat avoidance, targeting, and homing. Also called ES. Electronic warfare support data can be used to produce signals intelligence, provide targeting for electronic or destructive attack, and produce measurement and signature intelligence, also electromagnetic spectrum, FM 2‑0)

The act of fixing a gun in a prepared position from which it may be fired, FM 6‑30. (See Table 7‑15 for symbol)

employee misalignment                  A misassignment occurs when an employee is permitted or requested to perform major duties that are not officially designated in the employees’ position description. The reverse may also result in a misassignment. That is, the inclusion of major duties in the official position description that are not actually performed by the employee. Typically the causes of misassignments are:

     (1) failure to officially detail or temporarily promote an employee to temporary duties
          assignments in excess of 30 days; or,

     (2) failure to request official position description changes prior to assigning new duties
          on a continuing basis.

Managers and supervisors may assign work not described in an employee's position description on a temporary basis (30 days or less) for the sake of meeting short term mission requirements; however, a duty performed by the employee in excess of thirty days is considered a misassignment unless action has been initiated to officially detail the employee.

Factors contributing to misassignments include, but are not limited to,

     poor, haphazard delegation,
     inflated duties on position descriptions, and
     gradual accretion of duties (see also mission creep)

Notwithstanding the fact that it may sometimes be difficult to be one hundred percent accurate due to changing missions and shifting priorities, supervisors are [solely] responsible for the accuracy of all position descriptions within their assigned purview. As such, a periodic review of position descriptions should occur on an annual basis, when the organizational design changes, or when new missions are absorbed by the organization that will require corrective duties in a position description. The consequences of not attending to this important function could result in reduced efficiency, low employee morale, improper compensation (pay) for work performed, or quite possibly an employee-initiated complaint.
