When not in military capacity, to whom is the Coast Guard assigned?

The Coast Guard is assigned to the Department of Homeland Security when not operating under a military capacity. This assignment highlights the Coast Guard's role in national security, specifically in areas like maritime law enforcement, search and rescue, and immigration enforcement. As a part of the Department of Homeland Security, the Coast Guard works on various missions that contribute to the safety and security of the nation, such as defending the nation against terrorist threats and ensuring secure borders.

In a military capacity, such as during wartime or under specific presidential orders, the Coast Guard may be transferred to the Department of the Navy, but during peacetime or domestic operations, its responsibilities and oversight fall under the Department of Homeland Security, reflecting its primary focus on safety and protection of national interests at home.
