  ADMINISTRATIVE FORCE STRUCTURE
  12-20. The administrative force structure is the aggregate of military
  headquarters, organizations, facilities, and installations that are designed to
  man, train, and equip the OPFOR. After transferring control of its major
  fighting forces to one or more task-organized fighting commands, an
  administrative headquarters, facility, or installation continues to provide
  depot and area support-level administrative, supply, and maintenance
  functions. The logistics function of the administrative force structure is
  extensive and complex, serving as the major connecting link between the
  industrial base of the State and forces engaged in combat.
  FIGHTING FORCE STRUCTURE
  12-21. The OPFOR’s fighting force structure is a flexible organization. It
  receives logistics assets from the administrative force structure and tailors
  them to meet specific objectives, based on forces available, mission
  requirements, enemy forces, and the geography of the AOR. Tailoring affects
  both the number and type of subordinate combat units and the number and
  type of logistics units allocated to support them.
  LOGISTICS MISSIONS
  12-22. In operational (and tactical) logistics, three terms describe how the
  OPFOR provides support to the field. These terms are primary support, area
  support, and depot support.
  12-23. Primary support is a mission given to supply, services, transportation,
  and maintenance units that normally provide support directly to other units.
  This allows the primary support unit to respond directly to the supported
  unit’s request for assistance or supplies.
  12-24. Area support is a mission given to supply, services, transportation, and
  maintenance units that normally provide support to primary support units and
  other area support units. Lower-priority units may have to rely on area support,
  rather than receiving supplies and services directly from the next-higher echelon.
  12-25. Depot support is a mission given to national- or theater-level units
  that normally provide support to area support units. Depot support
  operations include the receipt, storage, and issue of war stocks and
  domestically produced armaments and materiel, and the overhaul and
  rebuilding of major end items.
  OPERATIONAL LOGISTICS CONCEPTS
  12-26. The OPFOR understands
  Operational Logistics Concepts
  that there is as much chance of
  an operation being brought to The OPFOR relies on the following logis-
  culmination by a lack of tics concepts:
  sufficient logistics support as • Centralized planning and decen-
  by enemy action. Therefore, it tralized execution.
  considers thorough logistics • Support forward.
  planning and preparation • Sustainment from other sources.
  essential to executing operation
