  Figure 4-4. Maneuver Defense (Example 1)
  4-93. A maneuver defense trades terrain for the opportunity to destroy
  portions of the enemy formation and render the enemy’s combat system
  ineffective. The OPFOR might use a maneuver defense when
  • It can afford to surrender territory.
  • It possesses a mobility advantage over enemy forces.
  • Conditions are suitable for canalizing the enemy into areas where the
  OPFOR can destroy him by fire or deliver decisive counterattacks.
  4-94. Compared to area defense, the maneuver defense involves a higher de-
  gree of risk for the OPFOR, because it does not rely heavily on the inherent
  advantages of prepared defensive positions. Units conducting a maneuver de-
  fense typically place smaller forces forward in defensive positions and retain
  much larger reserves than in an area defense.
  Defensive Lines
  4-95. The basis of maneuver defense is for units to conduct maneuver from
  position to position on a succession of defensive lines. In this case, the “line”
  defended on is not a continuous line of defenses, but rather a notional line on
  which one or more units have orders to defend for a certain time at a certain
  depth within a unit’s AOR. The OPFOR accepts large intervals between de-
  fensive positions on such a line. Part of the line may consist of natural or
  manmade obstacles or of deception defensive positions.
  4-96. These “lines” are not necessarily linear, in the sense of forming a
  straight line. Nor are they necessarily at regular intervals from one another.
