Which agency primarily oversees incident management in the United States?

The Federal Emergency Management Agency (FEMA) is the primary agency responsible for overseeing incident management in the United States. Its primary missions include coordinating the federal government's response to natural and man-made disasters, providing assistance to state and local governments, and ensuring that emergency management resources are effectively used.

FEMA plays a vital role in preparing for disasters, managing resources during incidents, and facilitating recovery efforts afterward. This position aligns with its directives to support communities in their disaster response and recovery processes, allowing for a more streamlined and effective management of incidents on a national level.

While the other agencies mentioned, such as the Department of Homeland Security, the National Guard, and the Federal Bureau of Investigation, are all involved in aspects of emergency management and response, their roles are more specific or supportive. The Department of Homeland Security encompasses FEMA but also covers broader areas of national security. The National Guard, while essential for providing support during disasters, typically operates at a state level unless federalized. The FBI focuses primarily on law enforcement and counter-terrorism rather than incident management as a whole. Thus, FEMA’s specialized mission and authority make it the primary agency for incident management.
