  6-145. The BCT commander may task a forward security force to conduct zone reconnaissance where the
  main body is to traverse. Based on the commander’s decision points, the security force conducts
  reconnaissance or target handover with the main body to maintain contact with the enemy. This handover
  allows the BCT to manage transitions between phases of the operation, or follow-on tasks and allows the
  security force to conduct tasks that support the BCT scheme of maneuver.
  6-146. The commander tailor’s organic sustainment assets to the mission. Battalion and company trains
  may be combined and accompany the main body. METT-TC determines the type and amount of supplies
  transported in these trains. Locating the combat trains with the battalion permits rapid resupply of the
  maneuver units than if they were further to the rear. Commanders, however, may decide to assign combat
  units to combat trains for their security if they determine that the combat trains do not have sufficient combat
  power to counter the anticipated threat.
  PREPARATION
  6-147. The BCT staff,specifically the S-2,constantly refines the enemy situation during preparation based
  on information and integrated intelligence products. One of the primary concerns of the BCT S-3 and S-2
  during preparation is to ensure the commander and staff have the latest information and that the COP is
  accurate, and the plan is still valid. The commander ensures, through confirmation briefs, backbriefs and
  rehearsals, that subordinates understand the commander’s intent and their individual missions as new
  information becomes available. Simple,flexible plans that rely on standard operating procedures(SOPs)and
  battle drills,and plans that units rehearse against likely enemy COAsare essential to success.
  6-148. The commander rehearses the operation from initiation to occupation of the final march objective or
  limit of advance. The commander prioritizes rehearsals of maneuver options, enemy COAs, and primary,
  secondary,and tertiary communications systems at all levels.Actions to consider during rehearsals include—
  (cid:122) Making enemy contact (advance guard).
  (cid:122) Making contact with an obstacle not identified and reported (advance guard).
  (cid:122) Making enemy contact (flank security force).
  (cid:122) Reporting requirements,engagement,and bypass criteria.
  (cid:122) Fire support.
  (cid:122) Maneuver.
  (cid:122) Unit transitions.
  (cid:122) Sustainment.
  EXECUTION
  6-149. The BCT maneuvers aggressively within its area of operations or along its axis of advance. Speed
  and security requirements must balance based on the effectiveness of the information collection effort,
  friendly mobility,effects of terrain,and enemy capabilities. The COP enables close tracking and control of
  the movement and location of units. The BCT (typically the tactical command post [TAC {graphic}])
  continually monitors the location and movement of security forces. This monitoring of security forces ensures
  adequate security for the main body and ensures the security forces are within supporting range of main body
  maneuver forces and fire support assets. The BCT also controls the movement of sustainment assets,
  adjusting movement to meet support requirements, to avoid congestion of routes, and to ensure
  responsiveness.
  Scheme of Maneuver
  6-150. Movement to contact startsfrom a line of departure or a specified point(s) at the time specified in
  the operation order. A limit of advance or a forward boundary controls the depth of the movement to contact.
  PLs, contact points, and checkpoints control the rate of movement. Fire support is planned throughout the
  movement to contact to provide accurate and continuous fires. Actions on contact,(see paragraph 5-47),are
  planned for and rehearsed. Subordinate echelons must quickly react to contact,develop the situation,report,
  and gain a position of advantage over the enemy. Maneuvering unit commanders coordinate forward passage
  through friendly forces in contact as required.
