"Joint forces performing CBRNE CM [Consequence Management] supporting civil authorities are part of domestic incident management and operate in accordance with the NRP. The NIMS forms the foundation for conducting domestic response operations. This framework provides a consistent approach for Federal, state, local, and tribal governments to work effectively and efficiently together to prepare for, prevent, respond to, and recover from domestic incidents, regardless of cause, size, or complexity. Joint forces conduct CBRNE CM in accordance with NIMS but maintain a distinct, independent chain of command. However, military personnel can and frequently will receive tactical direction from the on-scene commander and subordinates, especially in circumstances where small numbers of military personnel augment civilian response functions. Installation forces operating under immediate response authority stay under the control of the Service branch of the chain of command unless committed to the Federal response effort by the Secretary of Defense. Under NIMS, installation and joint forces may find themselves getting task direction from a civilian firefighter, law enforcement officer, or emergency medical technician, but this functional working relationship does not replace or circumvent the military chain of command. Key to success for joint forces conducting CBRNE CM is to establish and maintain unity of effort within the framework of NIMS while maintaining unity of command within DOD".
