  6-151. The primary focus of a movement to contact is the enemy force,which may be stationary or moving.
  Objectives can designate the movement of subordinate units and identify suspected enemy positions.
  Although an axis of advance can guide movement, there is the risk of enemy forces outside the axis being
  undetected and inadvertently bypassed. During a movement to contact, the intent of the commander is to
  maneuver quickly to defeat the enemy before the enemy can react. The commander avoids piecemeal
  commitment of the main body unless failure to do results in mission failure or prevented by restricted or
  severely restricted terrain. The BCT commander uses the advance guard to fix the enemy while the main
  body maneuvers to seek the assailable flank. The commander focuses on the enemy’s flanks and rear before
  the enemy can counter these actions.
  Maneuver Options
  6-152. The commander makes the decision to execute a maneuver option based on the progress of the
  advance guard’s initial engagement. The movement to contact generally ends with the commitment of the
  main body. The tactical options available to the BCT after contact are addressed in the following paragraphs.
  6-153. Attack. The commander directs an attack when the BCT has greater combat power than the enemy
  does or when the commander assesses that the BCT can reach a decisive outcome. The commander can direct
  an ambush against a moving or infiltrating force that is not aware of the presence of the friendly force.
  6-154. Defend. The commander directs a defense when the BCT has insufficient combat power to attack.
  The commander also directs a defense when the enemy’s superior strength forces the BCT to halt and prepare
  for a more deliberate operation.
  6-155. Bypass. The commander provides criteria detailing conditions for bypassing enemy forces. The unit
  in contact can bypass if authorized,but,if the bypassed force represents a threat,the unit must fix or contain
  it until released by the higher commander.
  6-156. Delay. A delaying force under pressure trades space for time by slowing the enemy’s momentum
  andinflicting maximum damage on the enemy,without decisively engaging,in principle. Once the advance
  guard (fixing force) makes contact with the enemy,the enemy may attempt a frontal counterattack in response
  to the BCT’s movement to contact. In this case,the fixing force defends itself or conducts a delay while the
  main body of the BCT maneuvers to attack.
  6-157. Withdraw. The commander directs a withdrawal when the BCT lacks the combat power to attack or
  defend,to improve a tactical situation,or to prevent a situation from worsening. Both direct-and indirect-fire
  assets from main body forces provide support to cover the withdrawal of the advance guard or lead elements
  of the main body. The commander also may employ obscuration to assist with breaking contact with the
  enemy.
  Bypassed Forces
  6-158. Bypassed forces present a serious threat to forces that follow the maneuver elements, especially
  sustainment elements. Units conducting a movement to contact do not bypass enemy forces unless authorized
  by higher authority. Bypass criteria, if established, are measures established by higher headquarters that
  specify the conditions and size under which enemy units may be bypassed. The BCT distributes the location
  and strengths of enemy forces throughout the area of operations so following units can move around these
  threats. Bypassed enemy units are kept under observation unless otherwise directed by the commander. The
  destruction or containment of the bypassed enemy forces becomes the responsibility of the higher commander
  if the commander permits the lead elements to bypass.
  Actions at Obstacles
  6-159. Once the unit detects an obstacle, the obstacle is immediately reported, and its location and
  description distributed. The element quickly seeks a bypass. If a bypass is available,the unit in contact with
  the obstacle marks the bypass; the unit reports the route of the bypass around the obstacle, also. The BCT
  breaches consistent with the breaching fundamentals of suppress, obscure, secure, reduce, and assault
  (described by the memory aid SOSRA) to create breach lanes and continue the movement to contact.
  Engineers support the breach effort by reducing the obstacle,improving the lanes,and guiding the main body
