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).
