Military and U.S. Coast Guard transport services utilize specialized vehicles and vessels—such as aircraft, ships, and ground vehicles—to move personnel, equipment, and supplies for defense and humanitarian missions. The U.S. Coast Guard, established in 1790, is a branch of the armed forces operating under the Department of Homeland Security, with authority to operate under the Department of Defense during wartime. It plays a crucial role in national defense, law enforcement, and environmental protection.
