Underwater Demolition Team TWELVE

Underwater Demolition Team TWELVE (UDT-12) was one of the U.S. Navy's elite special warfare units, established during World War II to conduct reconnaissance, demolition, and obstacle-clearing operations in advance of amphibious assaults. Activated in 1944, UDT-12 played a crucial role in the Pacific Theater, notably supporting landings at Okinawa by clearing mines and obstacles from beaches under enemy fire. Following the war, the team continued to serve in various capacities during the Korean War, adapting to new missions including intelligence gathering and sabotage operations. UDT-12's legacy contributed to the evolution of modern Navy SEAL teams, reflecting the transition from traditional demolition roles to broader special operations capabilities.
