It is an expeditionary formation that deploys with its supported brigade, including (for airborne forces) conducting parachute assault operations.
The BSB is responsible for protecting the BSA from low-level threats using its organic equipment and may provide limited support for other units passing through its area of operations as directed by the brigade commander.
The command sergeant major, as the senior enlisted member of the BSB, provides knowledge, experience and advice to the commander and communicates with the sergeants major of other supported units to resolve issues for the BSB.
[4] The role of the distribution company is to manage the daily receipt, storage, and issuance of supply class I, II, III, IV, V and IX in support of its parent brigade.
Instead the platoon is kept in reserve to conduct internal movement within the BSA or for high-priority missions.
The SSA serves as the point in which supplies are received and stored and would be established in a secure location which allows for easy access.
Field-level maintenance includes not only removal and replacement of components but repair of components, with the ultimate goal of returning systems to operational status as quickly and as close as possible to the point of failure or damage.
The recovery section provides welding and lift capability for the repair shops, recovery operations for BSB units and units operating within the BSA, and limited assistance to FSCs for evacuating equipment.
[14] The maintenance platoon provides shop and on-site field-level maintenance for the companies of the BSB, assistance to the FSCs, and (when able) additional support to other units traversing through the brigade's area of operation.
[15] Forward support companies (FSCs) are organic to the BSBs of a BCT, combat aviation brigade, and Special Forces Group.
This includes field feeding, bulk fuel, general supply, ammunition, and field-level maintenance to the supported battalion.
FSCs are structured similarly, with a headquarters section, distribution platoon, and maintenance platoon, with differences in maintenance and petroleum, oil and lubricant (POL) distribution capability.
