  9-154. When established, the field trains usually consist of the elements of the headquarters and
  headquarters company (battery or troop) and the battalion or squadron S-1 and S-4 sections and may include
  FSC elements not located in the combat trains. Field trains personnel help facilitate the coordination and
  movement of support from the BSB to the battalion or squadron. The battalion or squadron S-4 coordinates
  all unitsupply requests with the BCT S-4 and BSB. The BSB fills orders with on-hand stocked items through
  unit distribution to the FSC, typically located at the combat trains. Requests for items not on-hand in the BSA
  are forwarded to the BCT S-4.
  9-155. The FSC typically places personnel in the field trains that can facilitate the resupply of rations, water,
  fuel, and ammunition. These FSC elements should also enable the flow of class IV, VIII, and IX. FSC
  elements in the field trains may consist of the FSC XO or first sergeant, ammunition handlers, field feeding
  Soldiers, fuel handlers, motor transport operators, and supply sergeant or other representatives from the FSC.
  The food operations noncommissioned officer may coordinate ration ordering and class I break bulk
  configuration for units and Soldiers in the field trains.
  9-156. When established, the field trains CP (graphically depicted as the FTCP) serves as the battalion or
  squadron commander’s primary direct coordination element with the supporting BSB in the BSA. The field
  trains CP usually consists of the headquarters and headquarters company (battery or troop) XO and first
  sergeant, an S-4 and S-1 representative, and supply sergeant or representative. The headquarters and
  headquarters company XO or designated representative can control the field trains CP. The field trains CP
  serves the following functions:
  (cid:122) Synchronizes and integrates the BCT concept of support.
  (cid:122) Coordinates logistics requirements with the BSB support operations.
  (cid:122) Configures LOGPACs tailored to support requirements.
  (cid:122) Coordinates with the BCT for personnel services and replacement operations.
  (cid:122) Forecasts and coordinates future sustainment requirements.
  (cid:122) Coordinates retrograde of equipment.
  (cid:122) Coordinates retrograde of personnel (casualty evacuation, personnel movement, and human
  remains).
  9-157. Maneuver battalions and squadrons do not necessarily have to locate their field trains in the BSA.
  While it is common to have field trains co-located in the BSA, the mission variables of METT-TC can dictate
  the necessity to move the field trains forward closer to maneuver unit combat trains. With the field trains
  collocated in the BSA, the BCT will not utilize the distribution trucks and lift platforms of the distribution
  company fully as designed. As maneuver forces move forward, field trains may move forward outside the
  BSA in order to keep FSC assets closer and more responsive to the BCT’s maneuver. The distribution
  company then distributes supplies to the field trains or further forward if the situation permits. If the FSC
  establishes field trains at the BSA, they can receive commodities at the BSA and push them forward to the
  combat trains using organic distribution assets, enabling the distribution company to use its assets to weight
  the main effort or perform unit distribution to units not collocated in the BSA.
  COMPANY,BATTERY,AND TROOP ECHELONS
  9-158. Echeloning of support begins at the company (battery or troop) level. Companies (batteries or troops)
  within the BCT have no organic logistics organizations. Echeloning support within these units, if required,
  must be done with internal personnel and equipment used to facilitate or expedite logistics support within
  these units.
  9-159. The commander determines the composition of echeloned support, often referred to as company
  (battery or troop) trains, and may consist of the first sergeant, supply sergeant, and medic. Maintenance teams
  from the FSC may be included. This echeloned support expedites replenishment of subordinate elements
  using either the supply point distribution or the unit distribution method. The operation order must describe
  the method used.
  9-160. Supply point distribution requires unit representatives to move to a supply point to pick up their
  supplies. Supply point distribution is commonly executed by means of an LRP. The LRP may be any place
  on the ground where unit vehicles return to pick up supplies and then take them forward to their unit. In unit
