  Rehearsals
  This appendix will provide rehearsal guidelines for SHORAD commanders and
  leaders. The information focuses on preparing them to plan for, prepare and conduct
  effective rehearsals for their own units, regardless of echelon, and with supported
  elements. For additional information on rehearsals, see FM 6-0.
  INTRODUCTION
  D-1. Each rehearsal type achieves a different result and has a specific place in the preparation timeline. The
  first step in rehearsal planning is to determine the type rehearsal the unit will use to practice the operation
  prior to execution.
  D-2. Regardless of the type of rehearsal used, most successful ones share common rehearsal practices. The
  following are some of the best practices commanders and leaders can use to guide their rehearsal planning
  and rehearsal execution evaluation:
  * The commander or leader establishes a standard for a successful rehearsal.
  * Commanders and leaders emphasize critical actions and key events that trigger friendly actions.
  * Rehearsal occurs near or on terrain similar to the actual operation terrain.
  * Rehearsal occurs under the same conditions (for example, weather and time of day) as expected
  during the operation.
  * Rehearsals identify problem areas, contingency actions, and enhance coordination.
  * Rehearsals include all information from the operations overlay including known and suspected
  enemy positions, airspace coordinating measures, and names of key terrain features.
  * Rehearsals use the decision support matrix and the decision support template as guides.
  * Critical actions in an operation are practiced.
  D-3. Rehearsals must be planned, prepared, and executed. The planning section beginning on page D-5
  addresses rehearsal planning considerations and recommended responsibilities for ensuring effective
  rehearsals. The rehearsal preparation section presents checklists that focus on the responsibilities of the
  commander, executive officer, and staff to make rehearsal execution run smoothly. The execution section
  identifies commander and staff responsibilities and SHORAD rehearsal step-by-step actions.
  REHEARSAL TYPES
  D-4. Each rehearsal type achieves a different result and has a specific place in the preparation timeline.
  There are four types of rehearsals: the backbrief, combined arms rehearsal, support rehearsal and the battle
  drill or SOP rehearsal.
  BACKBRIEF
  D-5. A backbrief is a briefing by subordinates to the commander to review how subordinates intend to
  accomplish their mission. It is used in conjunction with other rehearsals to ensure the operation and rehearsal
  standards are met. A subordinate briefs the commander or leader on what the subordinate's orders are and
  what the subordinate is supposed to do and why. This briefing allows commanders to clarify the commander's
  intent early in subordinate planning and identify any problems in the concept of operations.
  D-6. Commanders and leaders should conduct backbriefs with subordinates at the following critical times:
