  Table A-6. A completed matrix example for essential fire support tasks (memory aid PLOT-CR)
  Phase: II Assault on Objective Bears
  Task (what): Essential Fire Support Task (EFST) 1: Provide obscuration fires to disrupt the enemy's ability to observe
  breaching operations.
  EFST 2: Provide suppressive fires to disrupt the enemy mechanized infantry platoons’ ability to place effective direct
  fire on the breach site.
  Purpose (why): EFST 1 Purpose 1: Enable the successful breaching operation.
  EFST 2 Purpose 2: To enable the successful breaching operation.
  Priority of fire: Field Artillery: A Company; Mortars: B Company.
  Allocations: A Company 1x Critical Friendly Zone; C Company 1x FA Priority Target.
  Positioning guidance: Mortars move along Route REDLEG and occupy mortar firing position 1 (azimuth of fire 1600);
  in place ready to fire not later than H+ 30 minutes.
  Restrictions/FSCMs: Coordinated fire line is Phase Line RED; No-Fire Areas 1 & 2 in effect.

  ESSTENTIAL FIELD ARTILLERY TASK DEVELOPMENT
  A-20. A task for the FA that must be accomplished to achieve an EFST. A fully developed EFAT has a task,
  purpose, method, and effects. The task describes the effects of fires against a specific enemy formation. The
  effects of fires include destroy, neutralize, suppress, screen, or obscure. The purpose is a summary of the task
  and purpose from the EFST. The method describes how the task will be accomplished by assigning
  responsibilities to the FA firing unit. The method is described by covering three categories priority,
  allocation, and restrictions. Priority provides the firing unit with priority of fires and priority of survey.
  Allocations include movement triggers, routes, PAA, azimuth of fire, priority targets, FPF, and radar zones.
  Restrictions cover FSCMs, ACMs and survivability movement criteria. Effects is a quantification of the
  EFAT and positioning of FA units. For an example of an EFAT check list, (see table A-7 and table A-8 on
  page A-10).
