  Division Sustainment Brigade
  9-174. The DSB is assigned to a division. The DSB is a renamed sustainment brigade. The DSB commander
  is the primary senior advisor to the division commander and the deputy commanding general (support) for
  the sustainment warfighting function. The commander is responsible for the integration, synchronization, and
  execution of sustainment operations at echelon. The DSB employs sustainment capabilities to create desired
  effects in support of the division commander’s objectives. Depending upon operational and mission
  variables, the DSB can command up to seven battalions. Figure 9-5 and figure 9-6 on page 9-36 depict
  notional taskorganized DSBs in support of an Infantry division and an Armored division respectively. The
  DSB and its subordinate units assigned to a division provides direct support to all assigned and attached units
  in an operational area as directed by the division commander. The DSB provides general support logistics,
  personnel services, and financial management to non-divisional forces operating in the division area of
  operations. A task organized DSB assigned to a division includes an organic division sustainment troops
  battalion (known as DSTB) and an organic DSSB to support tactical-level sustainment operations. The DSB
  coordinates and synchronizes tactical-level sustainment operations to meet current and future operations. The
  DSB is dependent on the division staff for long-range planning capability. The DSB and its subordinate units
  must be able to move and displace at the pace of large-scale combatoperations. Additional modular CSSBs
  and companies may be attached to the DSB to sustain large-scale combat operations.
