  armor, infantry, field artillery, air and missile defense, military police, civil affairs, military information
  support elements, engineers, CBRN, EOD, or other forces or capabilities. Some of this augmentation may
  come from other BCTs. Multifunctional and functional brigades can also support BCT operations (See
  FM 3-96 for additional information on BCT operations).
  Expeditionary Sustainment Command
  4-47. The ESC is the corps’ command for the integration and synchronization of sustainment in an
  operational area. The ESC is assigned to the corps and task-organized with functional and multifunctional
  sustainment units that provide general support for all units in the corps AO. The corps’ ESC commands and
  controls the sustainment units operating in the corps rear area. The ESC and its subordinate units provide
  general support to all units assigned and attached to the corps. A task-organized ESC assigned to a corps
  normally includes enablers such as a corps logistics support element, petroleum group, financial management
  support center, movement control battalion, and a sustainment brigade.
  4-48. The ESC assists the corps sustainment cell with planning and coordinating sustainment, planning for
  near-term operations, and synchronizing operational-level sustainment operations to meet current operations.
  The corps ESC is dependent on the corps staff for long-range planning capability. The ESC main command
  post positions itself where it can best support operations, generally in the vicinity of the corps rear command
  post. The ESC tactical command post provides the capability to integrate into other corps command posts as
  required. The ESC commander may perform the duties of deputy commanding general (support) if directed
  by the corps commander. The ESC also relies upon the corps for additional force protection, signal, and
  medical support. (See FM 4-0 for more information on the ESC.)
  Maneuver Enhancement Brigade
  4-49. The MEB is a multifunctional headquarters with limited organic structure and depends on the task
  organization of units for capabilities to conduct support area operations and defense support of civil
  authorities for the echelons it supports. Higher echelon commanders base the MEB’s task-organization on
  identified mission requirements for the echelon it is supporting. When properly task-organized the MEB can
  perform military police, engineer, and CBRN missions simultaneously, in addition to all of the doctrinal
  functions associated with being assigned an AO. The MEB performs these functions within its AO:
  * Support to base camp and base cluster defense.
  * Lines of communication security, maintenance, and movement control.
  * Liaison and coordination.
  * Construction.
  * Host-nation support integration.
  * Detainee operations.
  * Mobility and countermobility
  * Rear command post integration.
  4-50. The MEB supports an Army, joint, interagency, or multinational headquarters. The MEB headquarters
  is staffed and optimized to conduct combined arms operations integrating a wide range of functional branches
  and combat forces. The MEB organizes, provides, or employs battalion task force and company team
  combined arms technical experts to conduct maneuver support tasks throughout an AO. The MEB may
  include a mix of CBRN, civil affairs, engineer, military police, and potentially air defense artillery units in
  addition to a tactical combat force. The number and type of organizations placed under this brigade depends
  on the mission, threat, and number and type of battalions or companies operating in the brigade’s AO. The
  MEB provides staff planning for and command and control of the units required to conduct decisive action
  in the echelon support area. Current Army force structure places all MEBs in the Army Reserve and the Army
  National Guard.
  4-51. A corps commander can task-organize parts of a MEB to a BCT or other brigade for a specific mission
  outside its AO or provide forces to complement or reinforce other organizations conducting select missions
  or tasks that support the main effort. However, specific or select missions does not imply long term. If the
  MEB becomes a force provider for an enduring period it could become ineffective in its ability to conduct
  support area operations. If conditions in the support area degrade, it is detrimental to the success of
