  the situation before enemy forces strengthen an assailable flank by preparing positions in depth or by
  engaging their reserve. Rapid movement around the enemy force’s flank is essential to prevent enemy forces
  from occupying previously prepared positions. Higher headquarters’ supporting efforts attempt to prevent
  the enemy from reconstituting reserves from other portions of the enemy front.
  2-70. After the initial envelopment of one flank, which places enemy forces at a disadvantage, units have
  many options. They may choose to exploit success by generating additional combat power along the same
  axis. Units can destroy or defeat the enveloped enemy force in place, or transition to another type of operation,
  such as an exploitation, pursuit, or encirclement.
  TURNING MOVEMENT
  2-71. A turning movement is a form of maneuver in which the attacking force seeks to avoid the
  enemy’s principal defensive positions by attacking to the rear of their current positions forcing them
  to move or divert forces to meet the threat. A turning movement differs from an envelopment because the
  force conducting a turning movement seeks to make enemy forces displace from their current locations,
  whereas an enveloping force seeks to engage enemy forces in their current locations from an unexpected
  direction. It can also be conducted using waterborne or amphibious means. Figure 2-18 graphically depicts a
  turning movement. Units frequently transition this form of offensive maneuver from the attack into an
  exploitation or pursuit. The turning force must also be capable of operating outside supporting distances for
  a set time. Only divisions and above can execute a turning movement. This is due to these echelons possessing
  the organic resources to organize a turning force that can operate outside the supporting distance of the main
  body and force enemy units out of their current positions. execute a turning movement.
