  ATTACK TO DESTROY
  3-18. An attack to destroy is designed to eliminate a target entity as a useful
  fighting force. Operational-level attacks to destroy usually focus on key en-
  emy combat formations or capabilities. Not every soldier or system need be
  destroyed for such an attack to be successful. Attacks to destroy are often fo-
  cused on a single component of an enemy’s combat system. For example, it
  may be enough to remove the enemy force’s ability to sustain itself or exer-
  cise effective command and control. Therefore, attacks to destroy are often fo-
  cused on the logistics and C2 systems of the target entity. Such attacks are
  most often conducted during regional operations. However, an attack to de-
  stroy may also occur during transition or adaptive operations, whenever the
  OPFOR can recognize and exploit a window of opportunity.
  ATTACK TO SEIZE
  3-19. An attack to seize is designed to gain control of a key terrain feature or
  man-made facility. The OPFOR does not adhere to the idea that seizure may
  be accomplished simply by placing a feature in weapons range. In the
  OPFOR lexicon, seize means to have OPFOR soldiers on and/or in the feature
  in question. Attacks to seize can occur as part of all strategic-level courses of
  action during OPFOR strategic campaigns. In regional operations, the sei-
  zure may facilitate the movement of an exploitation force. In transition or adap-
  tive operations, the seizure may be part of a campaign to control access into the
  theater.
  ATTACK TO EXPEL
  3-20. An attack to expel is used to force the defender to vacate an area. At-
  tacks to expel often have a strong information warfare (IW) component, so
  that the enemy removes himself from the area largely through a loss of re-
  solve. Attacks to expel typically focus on a key enemy capability or vulner-
  ability. Attacks to expel are primarily conducted within the context of transi-
  tion or adaptive operations.
  PLANNING OFFENSIVE OPERATIONS
  3-21. For the OPFOR, the key elements of planning offensive operations are
  • Determining the level of planning possible (planned versus situational
  offense).
  • Organizing the battlefield.
  • Organizing forces.
  • Organizing IW activities (see Chapter 5).
  • Determining the objective of the offensive operation.
  3-22. Offensive actions during transition and adaptive operations are not
  able to rely simply on massing combat power at a decisive point. Such actions
  typically include increased use of
  • Infiltration.
  • Perception management (see Chapter 5) in support of operations.
  • Affiliated forces in support of operations.
