Chapter 5 5-6 ATP 4-90, C1 09 November 2021 commander’s momentum by shortening the lines of communication. The FLE operates out of a forward logistics base or support area and is typically commanded and controlled by the BSB SPO and assistant S-3. The BSB establishes an FLE based on tactical requirements. The BSB is the lowest echelon unit that can establish an FLE. The FLE’s composition is tailored to the supported unit’s composition and task. While mission variables dictate an FLE’s composition, the BSB often establishes an FLE with fuel assets, ammunition assets, water and class I supplies, recovery assets, and medical personnel. FSC maintenance elements continue normal operations so, typically, there is limited requirement for maintenance capability in an FLE while the BSA displaces. The FSCs continue to provide direct support to their assigned battalions. Due to its fixed location and extended period of operation, security if a significant concern for the FLE and requires a greater degree of security planning. . When displacing the BSA, an FLE enables the BSB mitigate disruptions in support to the BCT. The BSB’s capability to support the brigade is diminished while moving. Brigade planners should carefully consider the timing of BSB displacement, employment of an FLE, Role 2 capability and coverage, and composition of the FLE to ensure adequate support is maintained throughout the transition. During fires brigade displacement, the majority of support to fires brigade units will come from CSSB throughput. The BSB commander may need to coordinate with echelons above brigade sustainment units to provide augmentation to the FLE. This includes identifying and the positioning of EAB sustainment assets in close proximity to geographically dispersed forces to extend operational reach and prolong endurance. ECHELONS ABOVE BRIGADE Support organizations at EAB that provide support to a BCT normally consist of the DSB, DSSB, brigade logistics support element, and area medical support organizations. Sustainment brigades and CSSBs may reinforce the DSB and the DSSB. Each of these units contribute to the echeloning of sustainment to a BCT. Identifying, planning for, and requesting support from the DSB, DSSB, and medical support organizations (such as the medical brigade or multifunctional medical battalion) is critical before the start of an operation for the efficient echeloning of sustainment. Planners coordinate with echelons above brigade units in order to establish a support relationship if no command relationship exists. SUSTAINMENT BRIGADE Sustainment brigades are normally attached to a corps expeditionary sustainment command, known as an ESC, or theater sustainment command. The sustainment brigade attached to a corps expeditionary sustainment command commands and controls all assigned and attached units in an area of operations as directed by the corps commander providing logistics, finance and comptroller, and personnel services to forces operating in the corps AO. The corps commander determines the task organization for the sustainment brigade attached to a corps expeditionary sustainment command. A task-organized sustainment brigade attached to a corps expeditionary sustainment command normally includes attached CSSBs, a petroleum battalion, and a motor transportation battalion to support tactical-level sustainment operations. The sustainment brigade coordinates and synchronizes tactical-level sustainment operations to meet the current and future operations. See ATP 4-93, Sustainment Brigade for more information on the sustainment brigade. COMBAT SUSTAINMENT SUPPORT BATTALION The CSSB can be attached to sustainment brigades supporting a corps. The CSSB commands and controls all assigned and attached units in an area of operations as directed by the sustainment brigade commander. The unit performs maintenance, transportation, supply, field services, and distribution. The corps commander determines the task organization for the CSSBs. Task-organized CSSBs, normally include a composite supply company, support maintenance company, modular ammunition company, palletized load system truck company, inland cargo transfer company and a field feeding company. The CSSB synchronizes and executes logistics support to functional brigades and multifunctional support brigades attached to the corps. See ATP 4-93.1, Combat Sustainment Support Battalion for more information on the unit.
