What was the main purpose of the Naval Combat Demolition Unit (NCDU)?

The main purpose of the Naval Combat Demolition Unit (NCDU) was to train personnel specifically for operations in Europe during World War II. The NCDUs were created to facilitate the preparation of landing zones for Allied forces. Their primary focus included the demolition of obstacles, such as beach fortifications and mines, that would impede amphibious assaults, particularly in the European theater. By providing this vital support and training soldiers in demolition techniques, the NCDUs played a crucial role in ensuring the success of amphibious landings, notably during the invasions of Normandy and other areas in Europe. This training was essential for enabling swift and safe troop movements and had a significant impact on the overall strategy of the Allied forces during the war.
