  more. Auxiliary casements in the underground facility may hold fuel, water,
  food, medical supplies, clothing, or life support equipment.
  Short-Duration Facilities
  12-14. Short-duration storage facilities play a central role in any strategic
  campaign that may involve intervention by an extraregional power. For
  example, prior to conducting adaptive operations, the State plans, develops,
  and builds short-duration storage facilities for the pre-positioning of
  equipment and supplies to sustain deployed forces. The State attempts to
  anticipate outside intervention and plan accordingly. Logistics items are
  stockpiled or cached in underground caves and dugout holes, tents, or
  warehouses, and are dispersed over a wide area. These facilities can be
  considered a mini-supply depot. They also undergo extensive camouflage and
  concealment to reduce their detection signature.
  THEATER DISTRIBUTION NETWORK
  12-15. Theater distribution is the

  physical and resource networks.
  12-16. The physical network consists of fixed structures and established
  facilities to support distribution operations. It includes roads, airfields,
  railroads, hardened structures (warehouses and storage facilities), inland
  waterways, ports, and pipelines. The quantity, capacity, and capability of
  these structures and facilities determine the robustness of the distribution
  network.
  12-17. The resource network consists of personnel (military and civilian),
  organizations, materiel, and equipment. These resources operate within the
  physical network of the distribution system.
  TAILORED LOGISTICS UNITS
  12-18. The OPFOR concentrates the bulk of its logistics units at two
  levelstheater and operational-strategic command (OSC). This concentration
  supports the OPFOR philosophy of streamlined, highly mobile combat forces
  at the tactical level. These higher levels maintain the responsibility and the
  primary means for logistics support.
  12-19. Tailoring allows allocation of logistics resources to the combat forces
  most essential to mission success. It also allows the OPFOR to assign
  priorities for logistics support. Subordinate units receive assets according to
  the importance of their mission, the nature of the terrain, and the level of
  fighting anticipated. Commanders not only can reallocate their own resources
  in line with changes in the situation, but also can take away their
  subordinates’ organic resources and give them to other subordinates if the
  situation warrants.
