Example Checklist 30 April 2020 FM 3-09 A-1 Appendix A Development of Fire Support and Field Artillery Tasks This appendix includes an overview of development of EFSTs and EFATs. An EFST is a task given to a field artillery unit or organization that supports the commander’s scheme of maneuver. An EFST is an essential element of the fire support plan. The task must be clear, concise, and include the elements of task, purpose, method, and effect. EFATs must accomplish a well-defined result in execution of the fire support task. SECTION I – ESSENTIAL FIRE SUPPORT TASK A-1. The EFST states the supported maneuver task and the type(s) of effects the firing unit must provide for that phase of the operation. The task describes what FS must accomplish to support the operation. It consists of the objective, formation, and function. The purpose defines the friendly maneuver goal and states the supported maneuver commander's purpose and desired end state for the targeted enemy formation, function, or capability. The purpose describes the why of the EFST. The method is how we will engage the target using priority, allocation, and restrictions. The effect identifies the desired result or outcome the delivered fires and effects are to create. As the FSCOORD and fire support planners war-game a fire support task during planning, they identify assets to accomplish the task, and describe the desired effect to be created. There is no difference in the development of a FST and an EFST. A-2. The FS tasks that must be accomplished to support the maneuver commander are EFST. Failure to achieve an EFST may require the commander to alter the tactical or operational plan. There should only be one EFST per phase, similar to the designation of one main effort per phase. Fully developed EFSTs consist of a task, purpose, method and effect. The FA BN uses EFSTs that have a method of "FA" as the start point for defining EFATs. The task is described as the effect that fires must have on an enemy formation's function or capability. The task is enemy oriented. The purpose is described in terms of the benefit that accomplishment of the EFST gives to the friendly maneuver commander. This is described as being friendly oriented. The effect is the quantified, observable result of successful accomplishment of the task. The effect is stated as relative condition of the friendly force in relationship to the enemy. For an example of an EFST checklist, (see table A-1). Table A-1. Fire Support Task Development Checklist Purpose of fires – From the commander’s intent for fires Phase Task: Objective.
