  CHEMICAL, BIOLOGICAL, RADIOLOGICAL, AND NUCLEAR
  2-31. CBRN elements, battalion and below, are task-organized to the MEB to conduct CBRN operations
  based on the tactical situation. 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 span 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 national objectives.
  * Assess. Through information collection and dissemination, effective warning and reporting,
  modeling, and hazard awareness and understanding, CBRN and select medical staffs and units
  possess the ability to estimate the potential for (or the existence of) CBRN threats and hazards.
  Assessing hazards allows proactive decision making and encompasses all of the capabilities to
  evaluate the potential for CBRN threats and hazards in the operational environment, detect and
  model CBRN hazards, and determine the characteristics and parameters of hazards throughout the
  operational environment that bear on operational and tactical decisions.
  * Protect. CBRN and medical staffs and units provide the Army capabilities for protection against
  CBRN incidents. Protection is the preservation of the effectiveness and survivability of mission-
  related military and nonmilitary personnel, equipment, facilities, information, and infrastructure
  deployed or located within or outside the boundaries of a given operational area (JP 3-0). It
  encompasses the execution of physical defenses to negate the effects of CBRN hazards on
  personnel and material. Protection conserves the force by providing individual and collective
  protection postures and capabilities. Protecting the force from CBRN incidents includes hardening
  systems and facilities, preventing or reducing individual and collective exposures, or applying
  medical prophylaxes through FHP.
  * Mitigate. CBRN units and medical staffs provide the Army the ability to mitigate CBRN incidents
  by responding with the personnel, subject matter expertise, medical response/treatment, and
  equipment to reduce the impact of, or neutralize, the hazard. Contamination mitigation is
  described as the planning and actions taken to prepare for, respond to, and recover from
  contamination associated with all chemical, biological, radiological, and nuclear threats and
  hazards to continue military operations (JP 3-11). The mitigate function includes capabilities to
  negate hazards, such as the decontamination task.
  2-32. Table 2-3, page 2-22, provides an overview of CBRN units, planning requirements, and capabilities at
  the battalion level and below that may be task-organized to the MEB. For additional information on CBRN
  operations, see FM 3-11.
