  BRIGADE SUPPORT AREA
  7-44. The BSA is the sustainment hub of the BCT. Usually, the BSA is located near an MSR where there is
  minimum threat from enemy artillery and mortar fires. For this reason, the BSA usually locates far behind
  where units conducting reconnaissance and security operations are located. Normally, the BSA includes the
  BSB (less FSCs as applicable), the alternate command post for the higher headquarters (if formed), the
  squadron field trains, elements from adjacent units or separate companies, and other sustainment units from EAB.
  FORWARD LOGISTICS ELEMENT
  7-45. An FLE includes task organized, multifunctional logistics assets to address specific sustainment
  missions, which is characteristic of reconnaissance and security operations. The FLE operates from a forward
  logistics base or support area. The FLE represents the BSB commander’s ability to weigh the effort for the
  operation by drawing on all sustainment assets across the brigade. Additionally, the BSB commander may
  coordinate with EAB to provide support capabilities to augment the FLE in the concept of support. BSB
  support includes identifying and positioning EAB unit assets in proximity to geographically dispersed forces
  to extend the operational reach and prolong endurance. The intent for employing an FLE is to minimize
  tactical pauses to the reconnaissance and security plan and enable momentum for the commander.
  FORWARD ARMING AND REFUELING POINT
  7-46. The FSC is organic to support aviation operations as required by the combined arms battalion. The
  FARP provides fuel and ammunition for the sustainment of aviation maneuver units during decisive
  operations. Usually, FARPs employ to support aviation operations when the distance covered or endurance
  requirements exceed normal capabilities of the aircraft. (Refer to ATP 3-04.17 for more information.)
  SECURITY OF SUPPORT AREAS
  7-47. Within a support area, a designated unit provides area security, terrain management, movement control,
  mobility support, clearance of fires, and required tactical combat forces. Area security operations focus on
  the protected force, base, base camp, route, or area, which allows sustainment units to focus on their primary
  function. When commanders utilize sustainment units for security operations, logistical operations may be
  adversely affected. Security of sustainment efforts during reconnaissance resupply is a critical factor to
  successful operations. (Refer to ADP 4-0 for more information.)
  7-48. The security of the trains in the support area is the responsibility of the individual in charge of the
  trains. The best defense is to avoid detection. The following activities ensure trains security:
  * Select sites that use available cover, concealment, and camouflage.
  * Enforce strict movement and positioning discipline as well as noise and light discipline to prevent detection.
  * Establish a perimeter defense using the occupy procedures for AAs.
  * Establish rest plans.
  * Identify an alarm or warning system that would enable rapid execution of the defense plan without
  further guidance. Usually, the SOP includes the alarm, warning system, and defense plan.
  * Designate a reaction force.
  ECHELONS ABOVE BRIGADE SUSTAINMENT SUPPORT
  7-49. Units conducting large-scale combat operations and reconnaissance and security operations require
  sustainment support from EAB sustainment units, particularly in maintenance and medical support.
  Typically, an EAB sustainment brigade provides support to units conducting reconnaissance and security
  operations. The unit conducting reconnaissance and security may require EAB units to provide water
  purification, petroleum storage, and transportation support. The medical brigade and the multifunctional
  medical battalion provide additional medical capability as needed. The FSC, in conjunction with the unit S-4,
  requests EAB assistance through the BSB. (Refer to ATP 4-93 for more information on the sustainment brigade
  and the combat sustainment support battalion.)
