UDT 1

Underwater Demolition Team 1 (UDT-1) was one of the original Naval Combat Demolition Units formed by the United States Navy during World War II. Established in 1943, UDT-1 specialized in reconnaissance and demolition missions, clearing obstacles and mines from beaches ahead of amphibious landings in the Pacific Theater, including operations at Saipan, Tinian, and Iwo Jima. The team's pioneering tactics and bravery laid the groundwork for modern naval special warfare. Following the war, UDT-1 continued to evolve and eventually became part of the lineage leading to the formation of the U.S. Navy SEALs in 1962.
