  The MEDCOM (DS) provides direct or general support to the corps through the MEDBDE (SPT) thatwill
  have hospital centers and medical battalions (multifunctional) attached.
  Sustainment Brigade
  9-170. Sustainment brigades can be attached to a corps ESC. The sustainment brigade attached to a corps
  ESC commands and controls all assigned and attached units in an operational area as directed by the corps
  commander providing general support logistics, financial management, and personnel services to forces
  operating in the corps area of operations. The corps commander determines the task organization for the
  sustainment brigade attached to a corps ESC. A task organized sustainment brigade attached to a corps ESC
  normally includes attached CSSBs, a petroleum battalion and 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 for more information on the
  sustainment brigade.)
  Special Troops Battalion
  9-171. The special troops battalion is organic to the sustainment brigade. The special troops battalion’s role
  is to exercise command and control for all units assigned, attached, and OPCON to the sustainment brigade
  headquarters. The special troops battalion plans, prepares, executes, and assesses the internal support
  requirements for the sustainment brigade headquarters. Its core competencies are to establish a battalion CP,
  execute the operations process, and synchronize internal support operations in support of mission
  requirements. The battalion consists of a command group, unit ministry team, and coordinating staff. A
  battalion headquarters is organized to provide administrative support, life support, and communications for
  the sustainment brigade headquarters. Capable of operating at the tactical level throughout an operational
  area, it can command up to seven organizations. Organic to the special troops battalion is a headquarters
  company that includes a maintenance section, medical treatment team, and medical evacuation team.
  Assigned to the special troops battalion are a signal company, human resources company, and a financial
  management support unit. These units all support the special troops battalion, sustainment brigade
  headquarters, and all the organic, assigned, and attached units.
  Combat Sustainment Support Battalion
  9-172. The CSSB can be attached to sustainment brigades supporting a corps. The CSSB attached to
  sustainment brigades supporting the corps commands and controls all assigned and attached units in an
  operational area as directed by the sustainment brigade commander and conducts maintenance,
  transportation, supply, field services, and distribution. The corps commander determines the task
  organization for the CSSBs attached to sustainment brigades supporting the corps. Task organized CSSBs
  attached to sustainment brigades supporting the corps normally include a composite supply company, support
  maintenance company, modular ammunition company, palletized load system truck company and 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 for more
  information on the CSSB.)
  SUSTAINING THE DIVISION
  9-173. A division will conduct operations with their assigned DSB, and the organic DSSB of the DSB. The
  DSB provides materiel management capability to the division. The division’s assigned,task organized DSB
  provides general support for all units in or passing through their geographic area. The division and its
  subordinate units must be able to move and displace at the pace of large-scale combat operations. Divisions
  may have additional CSSBs attached to meet operational requirements. Multiple echelons above division
  sustainment units and elements of the MEDBDE (SPT) may be operating in the area alongside the DSB with
  its organic DSSB. Medical elements of the MEDBDE (SPT) are normally OPCON to the division commander
  and their parent medical organization retains administrative control. (See ATP4-93, ATP 4-93.1, and
  FM3-94 for additional information.)
