How did UDTs directly affect the casualties in amphibious operations?

The role of Underwater Demolition Teams (UDTs) was crucial in amphibious operations during WWII, particularly in minimizing casualties. Their primary mission was to successfully clear obstacles, such as underwater mines and other impediments, before troops hit the beaches. This advance clearance allowed the landing forces to approach the shore more safely, reducing the risk of encountering deadly defensive measures that could inflict heavy casualties.

When UDTs performed their operations effectively, they safeguarded the landing areas, which not only facilitated the safe landing of troops but also enhanced the overall success of the amphibious assault. By ensuring that obstacles were eliminated prior to the arrival of the main forces, UDTs played a direct role in decreasing the number of personnel who would be exposed to enemy fire or other dangers upon landing. Their expertise in underwater demolition and reconnaissance was therefore integral in creating a more favorable environment for the attacking forces.
