Which branch of the military primarily utilized UDTs?

The Underwater Demolition Teams (UDTs) were primarily utilized by the Navy. Established during World War II, UDTs were formed to conduct reconnaissance, demolitions, and other special operations in support of amphibious assaults. Their main role was to clear enemy obstacles from the beach and prepare for the landing of larger forces. The Navy's emphasis on naval operations and its unique requirement for specialized skills in underwater demolition made it the natural authority for developing and deploying UDTs.

The other branches, such as the Army and Air Force, had their distinct operational focus and methodologies that did not overlap with the maritime and amphibious missions typically handled by the Navy. The Coast Guard, while it does operate in maritime environments, specializes in different missions related to law enforcement, search and rescue, and environmental protection, rather than the specific demolitions and reconnaissance missions that UDTs were trained for. Therefore, the Navy's direct involvement in creating and utilizing UDTs solidifies its position as the primary branch associated with these specialized teams.
