Which of the following is a mission of the United States Coast Guard?

The United States Coast Guard has a mission to perform search and rescue, which is a key component of its responsibilities in ensuring the safety of life at sea. This mission involves responding to emergencies such as distressed vessels, individuals lost or in danger at sea, and natural disasters where maritime assistance is required. The Coast Guard operates under the Department of Homeland Security and plays a critical role in safeguarding maritime interests, including providing immediate life-saving assistance to those in peril on the water.

While other military branches are responsible for functions like conducting air operations, land warfare, or operating submarines, these activities fall outside the scope of the Coast Guard's primary missions. Their focus is primarily on maritime safety, security, law enforcement, and environmental protection within U.S. waters. This distinctive role emphasizes the importance of search and rescue, underscoring the Coast Guard's commitment to protecting lives and property on the seas.
