## Highlights

Numerous occurrences in the United States--both scheduled events and emergencies--require the Department of Defense (DOD) to coordinate, integrate, and synchronize its homeland defense and civil support missions with a broad range of U.S. federal agencies. In response to congressional inquiry, GAO examined the extent to which DOD has (1) identified clearly defined roles and responsibilities for DOD entities to facilitate interagency coordination for homeland defense and civil support missions, (2) articulated to its federal partners the DOD entities' approach toward interagency coordination, and (3) adopted key practices for managing homeland defense and civil support liaisons. GAO reviewed numerous DOD policy and guidance documents and interviewed officials from DOD and its partner agencies, including the departments of Homeland Security, Justice, Health and Human Services, and Agriculture; and the Office of the Director of National Intelligence.
