text: Mission Command
  3-101. Commanders and staffs must revise and refine their initial plan during preparation. The
  commander’s situational understanding changes over the course of the operations process as enemy actions
  require them to revise their plan. The ongoing reconnaissance and security operations generate both
  applicable combat information and unforeseen opportunities. During preparation, commanders confirm or
  deny assumptions made during planning. Commanders must revise and refine their operational plan when
  reconnaissance and security operations provide significant new information from PIRs or FFIRs.
  3-102. Finally, commanders and staffs conduct effective confirmation briefs and rehearsals. A confirmation
  brief is a brief subordinate leaders give to the higher commander immediately after the operation order is
  given to confirm understanding (ADP 5-0). The brief is the leaders’ understanding of the commander’s intent,
  their specific tasks, the BCT commander’s reconnaissance guidance, and the relationship between their
  mission and those of the other units in the operation (see ADP 5-0). Ideally, the commander conducts
  confirmation briefs in person with selected staff members.
  3-103. A rehearsal is a session in which the commander and staff or unit practices expected actions to
  improve performance during execution (ADP 5-0). Both confirmation briefs and rehearsals are essential to
  ensure that subordinate commanders and staffs understand the concept of operations and the commander’s
  intent. Rehearsals and confirmation briefs allow leaders to practice synchronizing operations at times and
  places critical to mission accomplishment. Effective rehearsals and confirmation briefs solidify the sequence
  of the operation’s key actions and improve mutual understanding throughout the unit. During preparation,
  commanders and staffs must ensure that the BCT and the Cavalry squadron are—
  * Securing and protecting the force.
  * Conducting aggressive reconnaissance to improve commanders’ situational understanding.
  * Revising, refining, and rehearsing the operational plan.
  * Integrating, organizing, and configuring their task organized, combined-arms, air-ground teams.
  * Ensuring forces and resources are ready for execution.
  Note. The BCT and the Cavalry squadron should also conduct a reconnaissance and security
  rehearsal to ensure that the BCT reconnaissance and security plan meets the commander’s intent
  and is synchronized throughout the BCT. The BCT commander, executive officer, S-2, S-3, fire
  support coordinator, Cavalry squadron commander, military intelligence company commander,
  and other BCT staff cells (for example, sustainment, information operations, and mobile
  communications) should attend. The rehearsal should last no longer than 1 hour and should focus
  on rehearsing reconnaissance and security tasks that address each decision point and PIR, and their
  associated NAIs.
  EXECUTE
  3-104. Execution is putting a plan into action by applying combat power to accomplish the mission. (Refer
  to ADP 5-0 for more information.) In execution, commanders, staffs, and subordinate commanders focus
  their efforts on translating decisions into actions. During execution, the tactical situation changes rapidly.
  Operations the commander originally envisioned during planning may bear little resemblance to actual
  events. Subordinate commanders require maximum latitude to take advantage of unforeseen situations in the
  form of both opportunities and challenges to execute actions on contact, develop the situation through action,
  and meet the commander’s intent, even when the original order no longer applies.
  3-105. Cavalry organizations assist BCTs in developing the situation through action. Cavalry organizations
  within the BCTs must effectively seize the initiative through combined arms, air-ground teams and execute
  decision point tactics.
  Seize the Initiative through Combined-Arms, Air-Ground Team
  3-106. Reconnaissance and security operations, by their nature, are combined arms, air-ground operations.
  These operations provide the commander with information and intelligence to reduce uncertainty and enable
  rapid decision-making. Moreover, the same combined arms, air-ground teams can present enemy forces with
  multiple forms of contact, forcing them to react continuously. Aviation assets provide critical complementary
