  headquarters—normally a corps. A division typically commands between two and five maneuver brigades,
  a combat aviation brigade (CAB), division artillery, and a DSB. It task organizes its assigned and provided
  units to accomplish its mission according to mission variables. See FM 3-94 and ATP 4-91 for additional
  information on the division.
  2-91. The division’s primary purpose is winning battles and engagements. During limited contingencies, it
  can organize itself to serve in multiple competencies. When the division is uncommitted to a specific
  operation, it focuses on building and sustaining readiness to prevail in large-scale combat operations. A
  division may also serve in the following roles:
  • Tactical headquarters.
  • ARFOR headquarters.
  • Joint force land component headquarters.
  • JTF headquarters.
  DIVISION SUSTAINMENT BRIGADE
  2-92. The DSB is assigned to a division. The DSB synchronizes and integrates sustainment for the division.
  It can provide command and control for up to seven battalions with two organic and optional space for five
  additional battalions. The role of the DSB is to provide command and control to all subordinate units and
  plan, synchronize, and integrate all sustainment support (including organic Role 1 medical support) for the
  division. The DSB performs the following functions: distribution management and operations, transportation,
  supply support, field maintenance, personnel services, and OCS requirements determination in coordination
  with subordinate units and the division staff. For additional information on the DSB and its organic
  capabilities, see ATP 4-91.
  DIVISION SUSTAINMENT SUPPORT BATTALION
  2-93. The division sustainment support battalion (DSSB) is a multifunctional battalion that is organic to the
  DSB and provides logistics support to a division. Its organizational design includes three organic companies.
  The DSSB has the capability to command and control up to four additional companies, detachments, or teams
  and synchronizes, integrates, and controls the execution of logistics operations for the division. For additional
  information, see ATP 4-91.
  DIVISION SUSTAINMENT TROOPS BATTALION
  2-94. The DSB also includes an organic division sustainment troops battalion to support tactical-level
  sustainment operations. It may command and control up to seven companies or teams based on mission
  requirements. This battalion’s role is to provide command and control for organic, assigned, and attached
  units and integrate, synchronize, and control the execution of operations for HR, financial management, and
  field services (field feeding and mortuary affairs) units supporting division operations.
  ADDITIONAL ECHELONS ABOVE BRIGADE SUSTAINMENT CAPABILITIES
  2-95. The Army has other organizations that assist with executing sustainment operations in addition to those
  discussed above. The motor transport, petroleum support, movement control, EOD, and terminal battalions
  provide logistics support to division and corps formations as well as enabling units operating throughout the
  AOR. These battalions can be task organized to sustainment brigades and DSBs to provide critical logistics
  capabilities in an operational area. The modular ammunition, support maintenance, composite and functional
  transportation, composite and functional supply, HR, and watercraft companies and detachments provide
  specific capabilities and execute complex operations. These companies can be task organized into DSSBs,
  CSSBs, and functional battalions to meet specific requirements.
  BRIGADE
  2-96. Brigade types include maneuver brigades, multifunctional brigades, and functional brigades. Maneuver
  brigades are the Army’s primary combined arms, close-operations force, and principal ground maneuver
  units of the division. They have organic capabilities including battalion-sized maneuver, field artillery,
  reconnaissance, and sustainment units. Each BCT has organic medical support for Role 1 and 2 medical
  operations. The three types of maneuver brigades are armored, infantry, and Stryker. Maneuver brigades
  normally operate as part of a division.
