  Forward Arming and Refueling Point
  9-105. A forward arming and refueling point (FARP) is a temporary facility that is organized, equipped,
  and deployed as far forward, or widely dispersed, as tactically feasible to provide fuel and ammunition
  necessary for the sustainment of aviation units in combat. Establishing a FARP allows commanders to extend
  the range of aircraft or significantly increase time onstation by eliminating the need for aircraft to return to
  the aviation unit’s central base of operations to refuel and rearm. FARPs may be task organized to provide
  maintenance support as well as air traffic control services, if required.
  9-106. A FARP is an example of supply point distribution. Commanders employ FARPs in support of
  aviation operations, generally by the distribution company of an aviation support battalion, when the distance
  covered, or endurance requirements exceed normal capabilities of the aircraft. They may also use FARPs
  during rapid advances, when field trains cannot keep pace. (See ATP 4-43 for additional information.)
  Modular System Exchange Operation
  9-107. Modular system exchange operation is the resupply technique to distribute and exchange a full
  flatrack, multi-temperature refrigerated container system, modular fuel system, and modular water tank rack
  by the supporting unit and retrograding an empty flatrack, multi-temperature refrigerated container system,
  modular fuel system, and modular water tank rack from the supported unit. Logisticians can apply this
  method of exchange to any modular system for commodities. Modular system exchange increases
  distribution throughput capability, extends operational reach, and prolongs the endurance of maneuver forces.
  The use of flatrack distribution and exchange forward in the BCT area of operations increases the supported
  maneuver commander’s tactical flexibility and decreases the sustainment transportation asset’s time on
  station when resupplying. A DSSB can also conduct modular system exchange operations with a BSB or
  FSC. (See ATP 4-90 for additional information.)
  OPERATIONAL CONTRACT SUPPORT
  9-108. Operational contract support is the process of planning for and obtaining supplies, services, and
  construction from commercial sources in support of combatant commander directed operations. While
  varying in scope and scale, operational contract support is a critical force multiplier in unified land operations,
  especially long-term stability operations. (See ATP 4-10 for additional information.)
  9-109. Contracting and purchasing will likely be a method of sustainment that helps to round out the BCT’s
  concept of support. BCTs must have trained and ready contracting officer representatives (CORs), field
  ordering officers, and pay agents. These designated personnel must be carefully selected, as they will make
  up the acquisition team within the BCT. They must work closely together as these personnel are part of a
  larger acquisition team that includes the contract and financial management experts, external to the BCT,
  who will provide the guidance and direction to each COR, field ordering officer, and pay agent to meet unit
  needs. (See ATP 4-10for additional information.)
  9-110. The COR (sometimes referred to as a contracting officer’stechnical representative) is an individual
  appointed in writing by a contracting officer. Responsibilities include monitoring contract performance and
  performing other duties as specified by their appointment letter. The requiring unit or designated support unit
  normally nominates a COR. (See ATP 4-10.)
  9-111. A field ordering officer is an individual who is trained to make micro purchases within established
  thresholds (normally with local vendors) and places orders for goods or services. A pay agent is an individual
  who is trained to account for government funds and make payments in relatively small amounts to local
  vendors. While performing as field ordering officers or pay agents, individuals work for and must respond to
  guidance from their appointing contracting and finance officials. One individual cannot serve as both field
  ordering officer and pay agent. Property book officers cannot serve as field ordering officers or pay agents.
  Field ordering officers and pay agents must be careful when dealing with local nationals because field
  ordering officers and paying agents have a ready source of cash, local nationals may overestimate the
  influence of field ordering officers and pay agent teams. (See ATP 1-06.1 for additional information.)
  Considerations for field ordering officers and pay agents include—
