Which technological advantage did UDTs utilize during their operations?

The correct choice highlights the significance of advanced diving gear, which was crucial for Underwater Demolition Teams (UDTs) during their operations. This gear greatly enhanced their ability to conduct underwater reconnaissance and demolition missions. The advanced diving equipment allowed UDTs to operate effectively in various marine environments, enabling them to execute tasks such as clearing obstacles, scouting beach landings, and supporting amphibious assaults.

The development of specialized diving suits and breathing apparatus improved their operational efficiency by allowing them to dive deeper and for longer durations, ensuring that they could complete their missions under challenging conditions. Overall, the use of advanced diving gear represented a vital technological advantage that contributed to the success of UDT operations in WWII.
