assumed responsibility for civil defense. Nevertheless, DoD continued to maintain and develop resources for civil defense, but with dispersed, overlapping, and informal authorities for growing and coordinating them. The ASD (HD&HA) now provides a single point of contact at DoD for FEMA, state and local disaster management agencies, and executive policymakers in the event that these resources need to be enhanced or mobilized.

Structure

The ASD (HD&HA) is supported by four deputy assistant secretaries (DASDs), each with coverage of a different mission area: *Deputy Assistant Secretary of Defense for Arctic and Global Resilience *Deputy Assistant Secretary of Defense for Defense Continuity and Mission Assurance (DC&MA) *Deputy Assistant Secretary of Defense for Homeland Defense Integration & Defense Support of Civil Authorities *Deputy Assistant Secretary of Defense for Western Hemisphere Affairs DASDs are appointed by the secretary of defense. Some are appointed from civilian life, while others are career defense officials. Once at the DASD level, the latter are considered a part of the DoD Senior Executive Service. The ASD (HD&HA) is also supported by a principal deputy, or PDASD, who helps manage the day-to-day operations.
