UDT (Underwater Demolition Team)

Underwater Demolition Teams (UDTs) were specialized Navy units responsible for clearing obstacles, mines, and conducting reconnaissance underwater, primarily during World War II and the Cold War. Their tasks included removing threats like underwater mines from beaches before amphibious assaults and performing underwater demolition work. UDT personnel were highly trained in diving, demolitions, and covert operations, making them key players in ensuring safe landing zones for larger military operations. Their expertise laid the groundwork for modern Navy SEAL teams, evolving into elite special operations forces skilled in underwater warfare, reconnaissance, and direct action missions.
