How did the NCDU and UDT contribute to the formation of modern SEAL Teams?

• A. NCDUs were formed for WWII beach obstacle clearance, and UDTs were founded in 1943 for hydrographic reconnaissance; SEAL Teams ONE and TWO were established in 1962 using personnel from UDTs.
• B. UDTs preceded NCDUs and both later merged into the Army's special forces.
• C. NCDUs did not influence SEAL development.
• D. SEAL Teams were formed in the 1980s without UDT involvement.

Answer: (A)

Beach obstacle clearance and underwater demolition units laid the groundwork for today’s Navy SEAL Teams. WWII saw NCDUs formed to clear beach obstructions so amphibious landings could succeed, while UDTs were created to perform underwater demolition and hydrographic reconnaissance that supported those landings. In 1962, SEAL Teams One and Two were formed using personnel and experience from UDTs, creating the new, cohesive maritime special-operations force. This combination of demolition doctrine from NCDUs and underwater capabilities from UDTs is why this history matters for the development of the SEALs. The other statements don’t fit the historical record, which shows the influence and timing of UDTs and NCDUs in shaping the SEALs, not a later formation or a merge into the Army.
