Homeland Defense

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.
