The Republic of Korea Naval Special Warfare (UDT SEAL) is a special warfare unit of Republic of Korea Navy. The flotilla is also known as ROKN UDT/SEALs, because UDT/SEALs is the most publicly known branch of the flotilla. ROKN UDT/SEALs are heavily influenced by the United States Navy SEALs, which initially provided funding and expertise in the unit's creation, and still maintain a strong relationship by regularly undertaking joint cross training (JCET) several times a year, utilizing US helicopter and submarine assets, and enrolling students each year in US Naval Special Warfare programs such as BUD/S and EOD school.
