About
In South Korea, the **Marine Special Rescue Unit (MSRU)** exists to respond to extreme maritime disasters. The MSRU is the nation's elite maritime rescue team, selecting only the best personnel from the Coast Guard, Navy, Special Warfare units, emergency medical services, and diving experts. They are the first to be deployed to sites difficult for general rescue teams to access, such as typhoons, ship collisions, fires, sinkings, large passenger ship accidents, missing divers, oil spills, and maritime catastrophes. Maintaining a 24-hour standby system, they continue rescue operations at great risk as long as there is a possibility of even a single survivor. Every member is like family, entrusting their lives to one another at sea, and they always carry out their missions with the goal of **"All Members Return."**
