  REHEARSAL EXECUTION
  D-42. During the rehearsal execution, the commander, executive officer, subordinate leaders, recorder and
  staff from the conducting headquarters have specific responsibilities before, during, and after a rehearsal.
  Before a rehearsal, the rehearsal director states the commander's expectations and orients the participants on
  the details of the rehearsal. During the rehearsal, participants rehearse their roles to ensure that they
  understand how their actions impact an operation. After a rehearsal, participants ensure that they understand
  any changes to the operation order and to any coordination required.
  D-43. Commanders command the rehearsal just as they command an operation. They maintain the focus and
  level of intensity, allowing no potential for confusion by subordinates. An effective rehearsal validates the
  synchronization (the what, when, and where) of tasks that subordinate units will perform to execute the
  operation and achieve the commander's intent.
  D-44. The executive officer—as the rehearsal director—ensures each unit accomplishes its tasks at the right
  time and cues the commander to upcoming decisions. The executive officer's script is the execution matrix
  and the decision support template. The executive officer as the rehearsal director—
  * Starts the rehearsal time.
  * Initiates a formal roll call.
  * Ensures everyone brings the necessary equipment, including organizational graphics, and
  previously issued orders.
  * Validates the task organization; link-ups must be complete or on schedule, and personnel and
  materiel must be on hand.
  * Ensures synchronization of the operational framework being used.
  * Synchronizes the timing and contribution of each participant.
  * Ensures that the most important events receive the most attention.
  * Keeps within time constraints.
  D-45. The operations officer (S-3)—
  * Portraits the friendly scheme of maneuver.
  * Ensures subordinate unit actions comply with the commander's intent.
  D-46. The intelligence officer (S-2) portrays the enemy forces and other variables of the operational
  environment during rehearsals. The S-2 bases actions on the enemy course of action that the commander
  selected during the planning process. The S-2—
  * Provides participants with current intelligence assessments.
  * Portrays the best possible assessment of the enemy course of action.
  * Communicates the enemy's presumed concept of operation, desired effects, and end state.
  * Explains other factors of the operational environment that may hinder or complicate friendly
  actions.
  * Communicates the key civil considerations of the operation.
  D-47. The logistics officer (S-4)—
  * Presents the logistics support concept.
  * Identifies critical sustainment shortfalls.
  * Communicates the transportation support identified for supply distribution and other sustainment
  actions.
  D-48. Subordinate leaders, using an established format, effectively brief their units' actions and
  responsibilities as well as record changes on their copies of the graphics or operation order.
  D-49. The recorder is normally a representative from the S-3. During the rehearsal, the recorder captures all
  coordination made during execution and notes any unresolved problems. At the end of the rehearsal, the
  recorder presents any unresolved problems for resolution, restates any changes directed by the commander,
  and estimates when a fragmentary order codifying the changes will follow.
