underwater demolition udt #4

Underwater Demolition Team 4 (UDT-4) was one of the original Navy Underwater Demolition Teams formed during World War II. Established in 1943, UDT-4 played a crucial role in amphibious operations, specializing in reconnaissance, obstacle removal, and demolition ahead of Allied landings in the Pacific Theater. The team participated in significant operations including the invasions of Saipan, Tinian, and Guam, where their actions helped pave the way for main assault forces. After the war, UDT-4 continued to serve in various capacities until its eventual transition into the modern U.S. Navy SEAL Teams during the early 1960s.
