The Coast Guard conducts search and rescue missions, enforces maritime laws, and protects the nation's waterways. In addition to its law enforcement duties, the US Coast Guard plays a vital role in responding to natural disasters and oil spills. It also aids in the navigation of commercial shipping and ensures the safety of recreational boating. The Coast Guard's diverse missions make it essential for maintaining safe and secure maritime operations.
