Who is responsible for building the comprehensive National Incident Management System, also known as the "National Response Network"?

The Department of Homeland Security is responsible for building the comprehensive National Incident Management System, which is also referred to as the National Response Network. This system is a vital framework designed to coordinate and streamline the response to incidents at all levels of government and within various sectors of society.

The National Incident Management System is crucial for creating a unified approach to emergency management, integrating efforts from federal, state, and local agencies, as well as incorporating resources from private organizations and non-profits. Since the Department of Homeland Security oversees national policies designed to prepare for and respond to disasters and emergencies, it plays a key role in developing and maintaining comprehensive systems like the National Incident Management System that facilitate effective coordination during incidents.

The other organizations mentioned in the choices have different roles within the broader emergency management framework but do not hold the primary responsibility for establishing the National Incident Management System.
