  FLEXIBILITY
  7-5. The BCT commander uses detailed planning, sound preparation, operations in depth, retaining
  reserves,and command and control to maintain flexibility. Flexibility requires the commander to visualize
  the battlefield to detect the enemy’s scheme of maneuver in time to direct fire and movement against it. The
  commander does not limit information collection efforts only to the forces in contact. The commander also
  concentrates on formations arrayed in-depth. The enemy may try to bypass areas where the defense is strong.
  Hence, the BCT commander ensures detection and the defeat of the enemy along all possible avenues of
  approach. The commander uses aviation reconnaissance and surveillance assets and cyberspace and
  electromagnetic warfare (EW) operations to support information collection. The BCT’s plan allows the
  commander to shift the decisive operation or the main effort quickly, if the situation changes, while
  maintaining synchronization. Inaddition,alternate and subsequent positions provide the flexibility needed to
  execute the defense,effectively. Small reserves may position near critical terrain or likely avenues of attack
  to enable rapid deployment to those areas. Blocking positions can be established to deny the enemy a chance
  for a rapid breakthrough.
  MANEUVER
  7-6. Maneuver allows the commander to take full advantage of the area of operations and to mass and
  concentrate resources where required. The BCT arrays and allocates forces in relationship to likely enemy
  courses of action (COAs). The BCT uses allocations based on the results of the relative combat power
  analysis of the BCT and enemy forces’assigned tasks and the terrain. The commander accepts risk along less
  likely avenues of approach to ensure that adequate combat power is available for more likely avenues of
  approach.
  7-7. Maneuver also encompasses defensive actions such as security and support area operations. In some
  cases, the commander must accept gaps within the defense, but must take measures to maintain security
  within these risk areas. The BCT integrates assigned or attached and echelon above brigade enablers, for
  example,surveillanceassets,reconnaissance and security forces,space and cyberspace capabilities,patrols
  (dismounted and mounted),combat outpost,observation posts,sensor outposts,or listening posts.Additional
  enablers include engineer reconnaissance teams,orchemical,biological,radiological,and nuclear (CBRN)
  reconnaissance forces, observation outposts,forward observer or spotter outposts,or other economy of force
  effort for these areas.
  MASS AND CONCENTRATION
  7-8. The BCT masses its combat power to overwhelm the enemy and regain the initiative. The commander
  must be able to concentrate forces and mass the effects of fires at the decisive point and time. To accomplish
  this, the commander may economize forces in some areas, retain a reserve, shift priority of fires, and
  maneuver repeatedly to concentrate combat power. Commanders accept risks in some areas to concentrate
  for decisive action elsewhere. Obstacles, security forces, and fires assist in reducing these risks as forces
  economize.
  7-9. Dependent on the operational framework, the commander designates a main effort to achieve
  concentration, and directs all other elements and assets to support and sustain this effort. The commander
  may reprioritize forces,designating a new main effort as the situation changes. The commander directs the
  task and purpose of supporting elements to create the conditions necessary for the main effort to accomplish
  its task and purpose. The commander narrows the width of subordinate areas of operations, focusing
  counterattack plans to support the main effort;assigns the main effort unit priority of obstacle preparation;
  gives the unit priority of indirect fire;and positions the reserve to influence the main effort’s area.
  7-10. Targets determined during the BCT’s planning process and refined during preparation is described
  broadly as physical and logical entities in cyberspace consisting of one or more networked devices used by
  enemy and adversary actors. These targets may be established as named area of interests (NAIs) and target
  areaof interests (TAIs) as appropriate. As part of cyberspace electromagnetic activities (CEMA),the division
  staff,in coordination with the corps staff,performsa key role in target network node analysis (see chapter 2)
  supporting the BCT’s cyberspace and EWeffort.
