  Tactical Mission Tasks
  The tactical mission tasks in this appendix describe the results or effects commanders
  want to achieve—the what of a mission statement. These tasks have specific military
  definitions.
  TASKS FOR TACTICAL MISSIONS
  B-1. Tactical mission tasks are the “what” of a mission statement. Most of these actions and effects have
  associated military symbols. Staffs use them in course of action development and sketches as part of the
  military decision-making process. Some are also graphic control measures or obstacle effects and are used
  as such. See table B-1 for a list of all tactical mission tasks.

  B-2. Commanders are not limited to the tactical mission tasks listed in this appendix in specifying desired
  subordinate actions in operation orders or operation plans. Many of the words and terms used to describe the
  what of a mission statement do not have special connotations beyond their common English language
  meanings. However, units must have a shared understanding of the what of the operation. Tasks involving
  only actions by friendly forces rarely provide sufficient clarity for a mission statement, thus the addition of a
  solid purpose coupled with the task adds understanding and clarity. Commanders ensure that missions
  assigned to subordinate units are consistent with their schemes of maneuver and resources allocated to those
  subordinates. For example, a defending unit requires far greater effort (resources) to destroy an enemy force
  than to disrupt it. Likewise, an attacking unit requires more combat power to clear enemy forces from a given
  area than to contain enemy forces in that same area.
  ATTACK BY FIRE
  B-3. Attack by fire is a tactical mission task using direct and
  indirect fires to engage an enemy from a distance. Friendly forces
  use direct fires, supported by indirect fires, to engage an enemy force
  without closing with the enemy to destroy, suppress, fix, or deceive
  that enemy. This task is usually given when the mission does not
  dictate or support occupation of the objective. An attack by fire is
  not done in conjunction with a maneuvering force. When assigning
  this task, the commander must state the desired effect on enemy
  forces, such as neutralize, fix, or disrupt. A commander may assign
  the force conducting an attack by fire to a battle position with either Figure B-1. Attack by fire task
  a sector of fire or an engagement area. The arrow points at the
  targeted force or objective, and the commander places the base of the arrow in the general area from which
