Which unit is known for destroying underwater obstacles during amphibious landings?

• A. Underwater Demolition Teams (UDT)
• B. Naval Combat Demolition Unit (NCDU)
• C. SEAL Team
• D. Rapid Assault Craft Unit

Answer: (B)

Clearing the way for an amphibious assault hinges on removing obstacles underwater and in the surf zone before the landing forces arrive. Naval Combat Demolition Units were formed specifically for this task, diving in to locate and destroy underwater obstructions with demolition charges so that landing craft could reach the beach safely. This focused mission—preparing a clear, obstacle-free approach for the assault—fits the question best. Underwater Demolition Teams also did underwater work, but their role and history span broader demolition and later evolution into other special forces, while SEAL Teams are broader modern units with a wide range of duties. Rapid Assault Craft Unit isn’t associated with underwater obstacle destruction in the historical sense described here.
