UDT 7

Underwater Demolition Team 7 (UDT-7) was one of the elite U.S. Navy units formed during World War II, specializing in amphibious reconnaissance and demolition operations. Established in 1944, UDT-7 played a critical role in the Pacific Theater, conducting pre-invasion beach reconnaissance and clearing obstacles for Allied landings, notably during the invasions of Iwo Jima and Okinawa. The team's expertise in underwater demolition laid the groundwork for modern naval special warfare tactics. Following World War II, UDT-7 continued to serve until the late 1940s, when it was eventually deactivated as part of the postwar military drawdown.
