This publication provides joint doctrine for the military response to mitigate the effects of a chemical, biological, radiological, or nuclear event or incident. Chemical, biological, radiological, and nuclear consequence management (CBRN CM) can be described as the overarching United States Government (USG) capability and the strategic national direction, to prepare for, respond to, and recover from the effects of a chemical, biological, radiological, and nuclear (CBRN) incident at home or abroad, and whether or not it is attributed to an attack using weapons of mass destruction (WMD). When required, the USG will coordinate its response to a CBRN incident in one of three ways based on the geopolitical situation. The Department of Homeland Security (DHS) is the USG lead agency for incident management that would include a domestic CBRN incident. Overseas, excluding homeland areas, the Department of State (DOS) is the USG lead for what is termed foreign consequence management (FCM). The geographic scope of the domestic CBRN response is associated with the US homeland. Generally, when tasked, Department of Defense (DOD) is a supporting agency, coordinating agency, or cooperating agency in support of DHS within the National Response Framework (NRF) and National Incident Management System (NIMS). A response could take place in a permissive or uncertain foreign operational environment. Requests for FCM originate from an affected nation through DOS. The military situation is when CBRN incidents occur requiring DOD to lead the USG response effort due to the lack of DOS and/or sufficient affected nation 'federal' presence as a result of military operations or for a CBRN incident on a DOD installation. CBRN CM provides the operational framework for those authorized measures DOD takes in preparation for anticipated CBRN incidents to mitigate the loss of life and property and to assist with the response and short-term recovery that may be required. This includes having plans, policies, procedures, training, and equipment necessary to effectively respond to CBRN incidents. This publication has been prepared under the direction of the Chairman of the Joint Chiefs of Staff. It sets forth joint doctrine to govern the activities and performance of the Armed Forces of the United States in operations and provides the doctrinal basis for interagency coordination and for US military involvement in multinational operations. It provides military guidance for the exercise of authority by combatant commanders and other joint force commanders (JFCs) and prescribes joint doctrine for operations and training. It provides military guidance for use by the Armed Forces in preparing their appropriate plans. It is not the intent of this publication to restrict the authority of the JFC from organizing the force and executing the mission in a manner the JFC deems most appropriate to ensure unity of effort in the accomplishment of the overall objective. Joint doctrine established in this publication applies to the commanders of combatant commands, subunified commands, joint task forces, subordinate components of these commands, and the Services. The guidance in this publication is authoritative; as such, this doctrine will be followed except when, in the judgment of the commander, exceptional circumstances dictate otherwise. If conflicts arise between the contents of this publication and the contents of Service publications, this publication will take precedence unless the Chairman of the Joint Chiefs of Staff, normally in coordination with the other members of the Joint Chiefs of Staff, has provided more current and specific guidance. Commanders of forces operating as part of a multinational (alliance or coalition) military command should follow multinational doctrine and procedures ratified by the United States.
