Preparing 07 December 2020 ATP 5-0.2-1 131 Rehearsal Types 3-32. Each rehearsal type achieves a different result and has a specific place in the preparation timeline. The four types of rehearsals are— Backbrief. Combined arms rehearsal. Support rehearsal. Battle drill or SOP rehearsal. Backbrief 3-33. A backbrief is a briefing by subordinates to the commander to review how subordinates intend to accomplish their mission (FM 6-0). Normally, subordinates perform backbriefs throughout preparation. These briefs allow commanders to clarify the commander's intent early in subordinate planning. Commanders use the backbrief to identify any problems in the concept of operations. 3-34. A backbrief differs from a confirmation brief (a briefing subordinates give their higher commander immediately following receipt of an order to confirm understanding) in that subordinate leaders are given time to complete their plan. Backbriefs require the fewest resources and are often the only option under time-constrained conditions. Subordinate leaders explain their actions from the start to the finish of the mission. Backbriefs are performed sequentially, with all leaders reviewing their tasks. When time is available, backbriefs can be combined with other types of rehearsals. Doing this allows subordinate leaders to coordinate their plans before performing more elaborate rehearsals. Combined Arms Rehearsal 3-35. A combined arms rehearsal (CAR) is a rehearsal in which subordinate units synchronize their plans with each other. A maneuver unit headquarters normally executes a combined arms rehearsal after subordinate units issue their OPORD. This rehearsal type helps ensure that subordinate commanders' plans achieve the higher commander's intent. Support Rehearsal 3-36. The support rehearsal helps synchronize each warfighting function with the overall operation. This rehearsal supports the operation so units can accomplish their missions. Throughout preparation, units conduct support rehearsals within the framework of a single or limited number of warfighting functions. These rehearsals typically involve coordination and procedure drills for aviation, fires, engineer support, or casualty evacuation (CASEVAC). Support rehearsals and combined arms rehearsals complement preparations for the operation. Units may conduct rehearsals separately and then combine them into full- dress rehearsals. Although these rehearsals differ slightly by warfighting function, they achieve the same result. Battle Drill or Standard Operating Procedure Rehearsal 3-37. A battle drill is a collective action rapidly executed without applying a deliberate decision-making process. A battle drill or SOP rehearsal ensures that all participants understand a technique or a specific set of procedures. Throughout preparation, units and staffs rehearse battle drills and SOPs. These rehearsals do not need a completed order from higher headquarters. Leaders place priority on those drills or actions they anticipate occurring during the operation. For example, a transportation platoon may rehearse a battle drill on reacting to an ambush while waiting to begin movement. 3-38. All echelons use these rehearsal types, but they are most common for platoons, squads, and sections. They are conducted throughout preparation and are not limited to published battle drills. All echelons can rehearse such actions as a command post (CP) shift change, an obstacle breach lane-marking SOP, or a refuel-on-the-move site operation.
