Which statement describes the NCDU's wartime task?

• A. Train divers in demolition
• B. Patrol coastal waters for enemies
• C. To destroy barriers and underwater obstacles
• D. Provide air support for naval operations

Answer: (C)

Destroying barriers and underwater obstacles to clear landing areas for amphibious assaults is the idea behind the NCDU’s wartime task. These units were specialized for removing the physical hurdles that could prevent ships and landing craft from reaching shore. They trained in demolition and carried explosives to blast away obstructions like beach barriers, nets, and underwater obstructions, often under enemy fire, so that the amphibious force could land safely and proceed with the operation. This focus on making the coast passable for attacking forces is why it’s the best description of their role. The other options describe activities that aren’t the primary mission of the NCDU: patrolling for enemies, providing air support, or simply training divers—those are separate roles or tasks, not the core assignment of clearing obstacles for landings.
