UDT-12

Underwater Demolition Team 12 (UDT-12) was a specialized unit of the United States Navy established during World War II. Activated in 1944, UDT-12 was trained for amphibious reconnaissance, demolition of obstacles, and beach clearing ahead of major assaults in the Pacific Theater, including operations in Okinawa and other island campaigns. The team’s expertise in underwater demolition and covert operations set the foundation for modern Naval Special Warfare tactics. After the war, UDT-12 continued to serve through the Korean War before eventually being integrated into the emerging Navy SEAL teams in the 1960s.
