Homeland defense

Homeland defense is under the Department of Defense (DoD). It protects the U.S domestic population, sovereignty, and its territory. The president directs it to act on external aggression and threats. Homeland Security in the United States is a federal agency. It protects the U.S citizens from threats. Its scope of work is in border control, aviation security, cybersecurity, and emergency response.

There are complexities in both intergovernmental and interagency environments. To reduce these complexities, Assistant Secretary of Defense (ASD) acts as a representative. The ASD will represent the Department of Defense (DOD) in each matter that deals with Homeland Security. The ASD works closely with local and state entities such as the Department of Homeland Security.

Homeland Defense and Homeland Security have significant differences in the manner they execute their mandate. These two bodies aim at securing the U. S, but they operate in various domains. The domains are such as air domain, maritime domain, and land domain. It is the responsibility DoD to safeguard the air domain. They work in hand with the Federal Aviation Administration (FAA) to warn pilots who are wayward. The DoD officers offer their services to the NCR Coordination Centre to serve them with interagency operations.

The maritime domain is secured by both the U. S Coast Guard and the U. S Navy. In 2006, DHS and DoD the two entities signed a memorandum to work together. In the land domain, it is the duty of Homeland Security to protect the citizens. However, in joint civilian personnel and Federal Military are supporting civil authorities, they are under the Secretary of Defense. In the area that they are operating the National Guard and DoD, the Governor acts as their commander. Hence, DoD is not limited to external threats only. It supports Emergency Support Functions and Incident Annexes of the National Response Framework.
