  SUPPORT ZONE SECURITY
  12-97. The OPFOR expects any enemy to make an effort to conduct
  reconnaissance, espionage, and diversionary action in its operational support
  zone. These enemy actions can be particularly effective in areas where the
  local population is not sympathetic to the OPFOR’s cause. In addition to
  these threats, the OPFOR anticipates attacks on its support zone by airborne
  and heliborne forces as well as larger-scale attacks by enemy operational
  maneuver forces.
  12-98. The OPFOR uses a security force to counter any threats in its support
  zone. Each OSC deploys a considerable counterintelligence effort. It can
  assign up to an entire division for security tasks. The security force is
  equipped and trained for conventional as well as unconventional warfare. As
  airborne and amphibious threats grow, there is increasing stress on
  deploying antilanding reserves, including, or even based on, heliborne units
  to provide a rapid reaction.
  MISSION SUPPORT SITES
  12-99. A mission support site (MSS) is a temporary base used by units that
  are operating at a considerable distance from their support zone, during an
  extended mission. The MSS may provide food, shelter, medical support,
  ammunition, or demolitions. The use of an MSS eliminates unnecessary
  movement of supplies and allows a force to move more rapidly. When
  selecting an MSS, consideration is given to cover and concealment, proximity
  to the objective, proximity to supply routes, and the presence of enemy
  security forces in the area. Security dictates that drop zones or landing zones
  be a considerable distance from an MSS, cache, or support zonealthough
  this may increase transportation problems.
  POST-COMBAT SUPPORT
  12-100. Strategic and operational logisticians are not only focused on
  supporting units in combat. They are also focused on other post-combat
  support requirements such as personnel replacement, weapon systems
  replacement, reconstitution, and receiving and preparing reinforcements.
  (For information on personnel replacement, see the Personnel Support
  section of this chapter.)
  WEAPON SYSTEMS REPLACEMENT
  12-101. Weapon systems replacement is simply a procedure for providing a
  weapon system to a combat unit. It involves processing the vehicle or
  equipment from a storage or transportation configuration to a ready-to-fight
  condition. It also involves the integration of a completely trained crew with
  the weapon system.
  RECONSTITUTION
  12-102. Reconstitution is performed in support of all combat operations.
  Although it is mainly a command and operations function, the actual
  refitting, supply, personnel fill, and medical actions are conducted by logistics
