text: Development of Essential Fire Support and Essential Field Artillery Tasks
  A-25. The purpose describes how the task will contribute to achieving the commander's intent. As with a FS
  task, this should identify the decisive point that will leverage the targeting effect. It is constructed very
  similarly, if not identical to a FS Task.
  A-26. To develop the method the FSCOORD, plans and details the priorities, allocations, and restrictions of
  the EFAT. The planning addresses movement functions and priorities, critical tasks to subordinate firing
  units during execution of the EFAT and other required tasks. The FSCOORD prescribes priority of fires,
  primary and alternate position areas, triggers for movement, priority of survey support, concept of movement,
  and the scheme of fires to achieve the EFAT.
  A-27. The desired effect quantifies the successful accomplishment of the task. An example of a desired effect
  is two BMPs destroyed, the desired effect is assessment-oriented and assists in the decision to reattack or not.
  A-28. To assess the required effects, sensors include observers, TA assets, infantry, Army aviation, and
  scouts. Effects are more than destroying the enemy equipment; they are quantifiable and observable. Accurate
  assessment and confirmation that the system has been destroyed or the desired effect has been created is the
  end result of the task. Disseminate the developed EFAT in the FA BN OPLAN or OPORD or in subparagraph
  3e of the higher HQ OPORD as the FA support plan.
  A-29. For completed examples of a EFAT using the memory aid target, trigger, location, observers, delivery,
  attack guidance, communications (refers as TTLODAC) see table A-9 page A-12 and table A-10 on page A-
