Homeland Security is a concerted national effort to prevent terrorist attacks within the US; reduce America—s vulnerability to terrorism, major disasters, and other emergencies; and minimize the damage and recover from attacks, major disasters, and other emergencies that occur. Homeland Defense is the protection of US sovereignty, territory, domestic population, and critical infrastructure against external threats and aggression, or other threats as directed by the President. Defense Support of Civil Authorities (DSCA) is support provided in response to requests for assistance from civil authorities for domestic emergencies, law enforcement support, and other domestic activities, or from qualifying entities for special events. Disaster management (or emergency management) is the term used to designate the efforts of communities or businesses to plan for and coordinate all the personnel and materials required to either mitigate the effects of, or recover from, natural or man-made disasters, or acts of terrorism.
In the past decade alone, natural disasters of considerable severity resulted in 699 Presidential Disaster Declarations, an average of nearly six per month. The US Armed Forces have a historic precedent and enduring role in supporting civil authorities during times of emergency, and this role is codified in national defense strategy as a primary mission of DOD. The nature of DSCA in the US presents a unique challenge based on the history of the country and the interaction of the federal, state, local, territorial, and tribal governments and private and nonprofit organizations. US military personnel must understand the domestic environment so they can employ military capabilities efficiently, effectively, and legally.
Perhaps one of the greatest challenges for a military staff is operating in or near the homeland and being subject to the inherent legal and jurisdictional responsibilities that accompany such operations. This challenge is set against the evolving range of threats to the homeland—to countering transnational organizations and individual actors of concern internal and external to the US.
