What type of reconnaissance do Underwater Demolition Teams specialize in?

Underwater Demolition Teams (UDTs) specialize in hydrographic reconnaissance, which involves collecting information about underwater environments and conditions. This type of reconnaissance is crucial for operations that require an understanding of the oceanography, underwater topography, and potential obstacles for both naval and amphibious operations. Hydrographic reconnaissance allows UDTs to gather data on sea floor characteristics, currents, tides, and other environmental factors that would affect mission planning and execution.

By focusing on hydrographic aspects, UDTs can help ensure the safety and success of naval operations, especially those that involve beach landings or underwater demolitions. Understanding the marine landscape is vital for navigating and achieving objectives effectively.
