  on the situation. The BCT monitors the actual number closely to avoid devoting too many or too few
  resources to the performance of dislocated civilian operations or detainee operations. The BCT protection
  cell works with the sustainment cell to ensure resources are available to construct and operate dislocated
  civilian camps or detention facilities for individuals acquired during the conduct of the mission. Military
  police and civil affairs organize to establish and support dislocated civilian operations and detainee
  operations.
  SECTION III – FORMS OF MANEUVER
  6-92. Forms of maneuver are distinct tactical combinations of fire and movement with a unique set of
  doctrinal characteristics that differ primarily in the relationship between the maneuvering force and the
  enemy (ADP 3-90). The forms of maneuver are envelopment, turning movement, infiltration, penetration,
  and frontal assault. Combined arms organizations synchronize the contributions of all units to execute the
  forms of maneuver to accomplish the mission. The BCT commander generally chooses one form to build a
  COA. The higher commander rarely specifies the specific offensive form of maneuver; however,
  commander’s guidance and intent, along with the mission, may impose constraints such as time, security,
  and direction of attack that narrows the form of maneuver to one option. The area of operations’
  characteristics and the enemy’s dispositions also determine the offensive form of maneuver selected. A single
  operation may contain several forms of maneuver,such as a frontal assaultto clear an enemy security zone,
  followed by a penetration to create a gap in the enemy’s defense.
  Note. Flank attack is no longer used as a defined Army term or listed as a form of maneuver.
  Commanders seek to engage an enemy’s assailable flank—a flank exposed to attack or
  envelopment (ADP 3-90). An exposed flank usually results from the terrain, the weakness of
  forces, the technical capability of an opponent, or a gap between adjacent units. See
  paragraphs6-93 through 6-95 for additional information.
  ENVELOPMENT
  6-93. Anenvelopmentis a form of maneuver in which an attacking force seeks to avoid the principal enemy
  defenses by seizing objectives behind those defenses that allow the targeted enemy force to be destroyed in
  their current positions (FM 3-90-1). At the BCT level, envelopments focus on seizing terrain, destroying
  specific enemy forces,and interdicting enemy withdrawal routes. The BCT commander’s decisive operation
  focuses on attacking an assailable flank. The operation avoids the enemy’s front, which is generally the
  enemy’s strength,where the effects of fires and obstacles are the greatest. The BCT commander prefers to
  conduct an envelopment instead of a penetration or a frontal assault because the attacking force tends to
  suffer fewer casualties while having the most opportunities to destroy the enemy. If no assailable flank is
  available,the attacking force creates one.
  6-94. The BCT commander uses boundaries to designate areas of operations for each unit participating in
  the envelopment. The commander designates PLs, supportbyfire and attack byfire positions, and contact
  points. The commander also designates appropriate fire support coordination measures,such as a restricted
  fire line orboundaries between converging forces,and any other control measures the commander feels are
  necessary to control the envelopment. The three variations of envelopment are single envelopment,double
  envelopment,and vertical envelopment.
  Note. An encirclement, no longer listed as a type of envelopment, typically results from
  penetrations and envelopments, or is an extension of exploitation and pursuit operations. See
  paragraphs 6-99 through 6-101 forinformation on encirclements.
  SINGLE ENVELOPMENT
  6-95. Singleenvelopmentis a form of maneuver that results from maneuvering around one assailable flank
  ofa designated enemy force (FM 3-90-1). The commander envisioning a single envelopment organizes forces
