Which organization includes both peacetime and wartime operations for the Coast Guard?

The Coast Guard operates under the Department of Homeland Security during peacetime and transitions to the Department of the Navy during wartime. This dual role reflects the organization’s unique position in national security, maritime law enforcement, and humanitarian efforts. The Department of Homeland Security is responsible for coordinating resource management, search and rescue operations, and protecting U.S. maritime interests, thus encompassing both peacetime and wartime missions. The other options do not have a direct impact on the Coast Guard's operational scope, as they primarily focus on different aspects of U.S. governance and public services, rather than the specific responsibilities involving national defense and maritime safety.
