  as the ARFOR. The corps can also serve as the coalition forces land component commander (known as
  CFLCC) when properly augmented with joint and multinational personnel. If the corps is uncommitted to
  specific combatant commander requirements, it focuses on building and sustaining readiness to prevail in
  large-scale combat operations. (See FM 3-94 for more information on corps operations.)
  DIVISION
  2-42. The division is the Army’s principal tactical warfighting formation during large-scale combat
  operations. Its primary role is to serve as a tactical headquarters commanding brigades. A division conducts
  operations in an area of operations assigned by its higher headquarters—normally a corps. Winning battles
  and engagements remains the division’s primary purpose. The roles of the division include acting as a tactical
  headquarters; or, with significant augmentation, an ARFOR headquarters, coalition forces land component
  command, or joint task force headquarters. (See FM 3-94 for more information on division operations.)
  BRIGADE COMBAT TEAMS
  2-43. Abrigadecombatteam(BCT)is the Army’s primary combined arms, close-combat maneuver force.
  BCTs maneuver against, close with, and destroy enemy forces. BCTs seize and retain key terrain, exert
  constant pressure, and break the enemy’s will to fight. They are the principal ground maneuver units of a
  division or a JTF.
  2-44. Divisions seek to employ BCTs in mutually supporting ways to the greatest extent possible. However,
  BCTs must be capable of fighting isolated from higher echelon headquarters and adjacent units during periods
  of degraded communication and when operations are widely distributed. (See FM 3-96 for more information
  on brigade combat teams.)
  MULTIFUNCTIONAL AND FUNCTIONAL BRIGADES
  2-45. Theater armies, corps, and divisions are task-organized with an assortment of multifunctional and
  functional brigades to support their operations. These brigades add capabilities such as intelligence, attack
  and reconnaissance aviation, fires, protection, contracting support, or sustainment.
  2-46. Multifunctional brigades provide a variety of functions to support operations and are normally attached
  toa corps or division, but they may be under a joint or multinational headquarters. Multifunctional brigades
  include combat aviation brigades, expeditionary combat aviation brigades, field artillery brigades,
  sustainment brigades, and maneuver enhancement brigades. (See FM 3-81, FM 3-04, ATP 4-93, and ATP 3
  09.24 for more information on multifunctional brigades.)
  2-47. Examples of functional brigades include security forces assistance, air defense artillery, civil affairs,
  expeditionary military intelligence, and engineer brigades. (See FM 3-34, FM 3-39, FM 3-57, ATP 3-96.1,
  ATP 2-19.1-1, ATP 2-19.1-2, ATP 2-19.3, and ATP 3-01.7 for more information on functional brigades.)
  COMMAND AND SUPPORT RELATIONSHIPS
  2-48. Command relationships define superior and subordinate relationships between commanders. They
  identify the degree of control of the gaining Army commander, and the type of relationship often relates to
  the expected longevity of relationship between the headquarters involved and identifies the degree of support
  thegaining and losing commander provide. These relationships consist of the following:
  (cid:122) Organic includes those forces that are assigned to and forming an essential part of a military
  organization as listed in the table of organization for the service. This relationship is established
  through organizational documents. Temporary task-organized units return to the control of the
  organic headquarters at the completion of the mission.
  (cid:122) Assigned is the placement of units or personnel in an organization where such placement is
  relatively permanent. The headquarters controls and administers the units or personnel for the
  primary function.
  (cid:122) Attachis the placement of units or personnel in an organization where such placement is relatively
  temporary (JP 3-0).
