  CHEMICAL, BIOLOGICAL, RADIOLOGICAL, AND NUCLEAR
  D-3. Chemical, biological, radiological, and nuclear operations include the employment of capabilities that
  assess, protect against, and mitigate the entire range of chemical, biological, radiological, and nuclear
  incidents to enable freedom of action (FM 3-11). CBRN capabilities support operations across the range of
  military operations by assessing CBRN threats and hazards, providing protection against CBRN hazards,
  mitigating CBRN incidents, and providing hazard awareness and understanding. The CBRN functions of
  assess, protect, and mitigate share a common fundamental purpose that fits within the protection warfighting
  function to achieve or contribute to support area operations. Table D-3 provides an overview of CBRN units,
  planning requirements, and capabilities at the battalion level and below that may be task-organized to the
  support area designated land owner or a tenant unit of the corps or division support area. For additional
  information on CBRN operations, see FM 3-11.

  CIVIL AFFAIRS
  D-4. CA forces execute CA core competencies and functions. The CA branch provides three core
  competencies nested within CA operations–CA activities, military government operations, and CA supported
  activities. CA functions are structured under each competency, organizing tasks and systems (people,
  organizations, information, and processes) into executable capabilities to create the desired effects. CA core
  competencies form the basis for training, organizing, equipping, and employing CA forces. The core
  competencies nest within the commander’s overall responsibility for planning and executing civil-military
  operations. The following are CA operations core competencies and their nested functions:
  * CA activities. Civil affairs activities are activities specifically planned, executed, and assessed by
  civil affairs forces that support the commander in order to synchronize, coordinate, and integrate
  indigenous populations and institutions, unified action partners, and interagency (FM 3-57). CA
  activities provide unique capabilities to the commander. CA activities consist of the following
  functions:
   Civil reconnaissance.
   Civil engagement.
   Civil information management.
