Coast guard units are specialized organizations responsible for maritime safety, security, and environmental protection. They operate in coastal areas and are tasked with search and rescue operations, law enforcement, and pollution control. These units often collaborate with other agencies to ensure safe navigation and respond to emergencies at sea. In many countries, such as the United States, the Coast Guard is a vital part of national defense and maritime law enforcement. Coast guard units utilize various vessels and aircraft to patrol waters, monitor shipping activities, and provide assistance to those in distress, ensuring the safety of both people and the marine environment.
