  Civil Affairs Battalion
  5-62. The role of civil affairs is to understand, engage, and influence unified action partners and indigenous
  populations and institutions, conduct military government operations, enable civil-military operations, and
  provide civil considerations expertise through the planning and execution of civil affair operations. Civil
  affairs facilitates situational understanding and addresses civil factors that influence military objectives and
  support unified action. A civil affairs battalion focuses on planning, enabling, and shaping civil affairs
  operations in support of the division. The majority of civil affairs that work with conventional forces are
  located in the Reserves, impacting their availability. Division commanders and staff must account for
  mobilization times and request forces early during planning in order to ensure their availability.
  5-63. A civil affairs battalion is task-organized based on mission requirements, but it usually consists of two
  to five civil affairs companies and can operate a civil-military operations center. The battalion can command
  and control up to seven civil affairs companies without staff augmentation. The civil affairs battalion can also
  provide a civil affairs planning team to assist the assistant chief of staff, civil affairs operations and division
  staff with planning and integrating civil affairs operations throughout the division AO. (See FM 3-57 for
  more details on civil affairs operations.)
  Explosive Ordnance Disposal Battalion
  5-64. The EOD battalion is a functional headquarters that directs EOD operations. The EOD battalion is
  responsible for detecting, identifying, evaluating, rendering safe, exploiting, and achieving final disposition
  of all explosive ordnance, including IEDs, in its AO. The battalion can also provide enabling support,
  analysis, support to targeting efforts, CWMD operations, and counter mine and theater exploitation. The
  EOD battalion is capable of supervising EOD operations for three to seven EOD companies. The EOD
  battalion is organic to the EOD group. The battalion may be attached or OPCON to a JTF, division, corps,
  or echelon above corps. (See ATP 4-32.1 and ATP 4-32 for more details on EOD units.)
  Chemical, Biological, Radiological, and Nuclear Battalion
  5-65. A CBRN battalion usually supports a division by providing a mix of units that specialize in
  decontamination, CBRN reconnaissance, and bio-detection. CBRN battalions support allocation, alignment,
  and logistics management for all assigned CBRN formations. CBRN battalions also provide the capability to
  assess, protect against, and mitigate CBRN threats and hazards and support CWMD operations.
  5-66. CBRN battalions are scalable, tailorable, and multifunctional formations that consist of a headquarters
  and two to five CBRN companies. A CBRN battalion may also be task-organized to a CBRN brigade, a
  MEB, or as an independent CBRN battalion to the division. A CBRN battalion depends on the division for
  sustainment support. (See FM 3-11 for more details on CBRN battalions.)
  Psychological Operations Company
  5-67. A division normally receives a psychological operations company. This company enables a division
  commander to influence—either directly or indirectly—foreign populations and militaries to achieve
  behavior changes consistent with stated objectives. A psychological operations company develops messages
  and actions in a series to address operational requirements of the maneuver unit. Series development consists
  of developing both product concepts and actions for a psychological effect. Tactical psychological operations
  companies develop messages and talking points for Soldiers and leaders. The company command section
  augments the division staff to provide military information support operations, senior leader engagement,
  and military deception planning assistance in coordination with the information operations staff element and
  the military deception officer. The psychological operations company commander works with the division
  staff to integrate attached military information support forces. The company requires sustainment support
  from a division as its organization does not include sustainment assets. (See FM 3-53 for more details on the
  psychological operations company.)
