  ASSIGNED FORCES
  5-40. A division routinely has units assigned to it. This includes two to five BCTs, a division sustainment
  brigade, a division artillery (DIVARTY) brigade, a combat aviation brigade, and a main command
  post-operational detachment.
  Brigade Combat Teams
  5-41. BCTs conduct decisive action to seize and retain key terrain, exerting constant pressure on the enemy,
  and break the enemy’s will to fight by maneuvering against, closing with, and destroying the enemy. BCTs
  are the principal ground maneuver units of a division. The three BCT designs—armored, infantry, and
  Stryker—make up the ground maneuver combat power of a division. All divisions can command any type of
  BCT. The three types of BCTs currently have two to three maneuver battalions, a cavalry squadron, a field
  artillery battalion, a sustainment battalion, and an engineer battalion. (See FM 3-96 for more details on
  BCTs.)
  Division Sustainment Brigade
  5-42. The division sustainment brigade is assigned to a division. The division sustainment brigade
  commander is the senior advisor to the division commander and to 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 division sustainment brigade employs sustainment
  capabilities to create desired effects in support of the division commander’s objectives.
