  with providing force protection for the entire AOR, including the rest of the
  functional forces; logistics and administrative elements in the support zone;
  and other key installations, facilities, and resources. The security force may
  include various types of unitssuch as infantry, SPF, counterreconnais-
  sance, and signals reconnaissance assetsto focus on enemy special opera-
  tions and long-range reconnaissance forces operating throughout the AOR. It
  can also include internal security forces units allocated to the operational-
  level command, with the mission of protecting the overall command from at-
  tack by hostile insurgents, terrorists, and special operations forces. The secu-
  rity force may also be charged with mitigating the effects of WMD.
  Deception Force
  3-56. When the IW plan requires combat forces to take some action (such as
  a demonstration or feint), these forces are designated as deception forces in
  close-hold executive summaries of the plan. However, wide-distribution cop-
  ies of the plan refer to these forces according to the designation given them in
  the deception story.
  Reserves
  3-57. At the commander’s discretion, forces may be held out of initial action
  so that he may influence unforeseen events or take advantage of developing
  opportunities. OPFOR offensive reserve formations are given priorities in
  terms of whether the staff thinks it most likely that they will act as a fixing,
  assault, or exploitation force. The size and composition of an offensive reserve
  is entirely situation-dependent. (See Chapter 4 for more detail on the various
  types of reserves, some of which are more common in defensive operations.)
  PREPARING FOR THE OFFENSE
  3-58. In the preparation phase, the OPFOR focuses on ways of applying all
  available resources and the full range of actions to place the enemy in the
  weakest condition and position possible. Commanders prepare their forces for
  all subsequent phases of the offensive operation. They organize their forces
  and the battlefield with an eye toward capitalizing on conditions created by
  successful attacks.
  ESTABLISH CONTACT
  3-59. The number one priority for all offensive operations is to gain and
  maintain contact with key enemy forces. As part of the decision-making proc-
  ess (see Chapter 2), the commander and staff identify which forces must be
  kept under watch at all times. The OPFOR will employ whatever technical
  sensors it has at its disposal to locate and track enemy forces, but the method
  of choice is ground reconnaissance. It may also receive information on the en-
  emy from the civilian populace, local police, or affiliated irregular forces.
  MAKE THOROUGH LOGISTICS ARRANGEMENTS
  3-60. The OPFOR understands that there is as much chance of an offensive
  operation being brought to culmination by a lack of sufficient logistics support
