  5-60. Following are additional tasks if encounter turns into a meeting engagement:
  * Destroy enemy reconnaissance and lead elements of the main body.
  * Determine the location of enemy assailable flanks.
  * Fix enemy forces to allow the main body to maneuver around the enemy strengths or
  through weaknesses.
  5-61. Staffs consider whether subordinate units conducting a guard operation require augmentation to
  execute their mission. Additionally, squadron commanders and staffs analyze requirements and notify the
  BCT commander of those tasks they cannot accomplish. The protected force commander then task organizes
  more augmentation or provides guidance on the prioritization of tasks.
  BCT PLANNING AND EXECUTION CONSIDERATIONS
  5-62. BCT commanders, or higher echelon commanders in the case of a TF or reconnaissance and security
  BCT conducting a guard, may augment the guard force with internal and external assets. Attack and
  reconnaissance aviation assists the guard force by gaining contact with enemy forces and reporting the
  enemy’s composition, disposition, and strength. Aerial assets can maneuver and assist in destroying enemy
  ground forces over large areas to weaker sections to maintain the guard. Aerial assets can be a quick reaction
  force to destroy enemy ground forces and reinforcements through Army attack aviation that canalize the
  enemy towards areas that the guard force fires plan supports. Indirect fire considerations are the same as in a
  screen, though the guarding unit may have more indirect fire assets at their disposal. BCT engineers conduct
  countermobility and survivability tasks to assist the guard force.
  ADVANCE GUARD (STATIONARY AND MOVING)
  5-63. An advance guard for a stationary BCT deploys forward and defends the main body. Once the unit
  makes contact, they continue to defend or delay within the area of operations consistent with the BCT
  commander’s intent.
  5-64. An advance guard for a moving force is offensive in nature, finding and defeating enemy units along
  the axis of advance. Units conducting an advance guard provide for the uninterrupted movement of the
  protected force. The advance guard engages in offensive tasks and movement to contact as needed to
  accomplish the mission. If the advance guard encounters enemy forces beyond its capability, the advance
  guard transitions to a defense to protect the BCT, continues reconnaissance to develop the situation, and
  prepares to pass elements of the main body forward. If the BCT is advancing as part of a division advance
  along widely separated axes, the advance guard moves with the main effort based on the factors of
  METT-TC (I). The supporting effort provides its own security (see figure 5-2).
