The U.S. Navy SEAL s of San Diego County trace their origins to the Underwater Demolition Teams (UDT) of World War II and the Korean War. Following these wars, the Frogmen, as they became known, were located first at the Amphibious Training Base in Oceanside, California, and then relocated to the Amphibious Training Base in Coronado, California, later renamed as U.S. Naval Amphibious Base (NAB) Coronado. In 1962, Pres. John F. Kennedy initiated the formation of Sea Air and Land (SEAL ) Teams, and SEAL Team One was also assigned to NAB Coronado. This history follows the UDT and SEAL team’s role through the Vietnam and the Gulf Wars as well as many other exploits, including interaction with the communities in which they live.
