What were the challenges faced by NCDU teams during WWII operations?

NCDU teams, or Navy Construction Battalions and Underwater Demolition Teams, faced a variety of significant challenges during their operations in World War II. Enemy fire posed a constant threat to the safety of NCDU personnel, as they conducted reconnaissance and demolition missions in enemy-held territories. Additionally, the terrain encountered during these operations could be extremely challenging, ranging from rocky beaches to heavily fortified coastal defenses, making navigation and execution of their missions difficult.

Difficult weather conditions further compounded these challenges, as operations often had to be carried out in adverse weather, which could include strong currents, high seas, or inclement weather that hindered visibility and mobility. These factors combined to create a highly demanding operational environment for NCDU teams, which required them to be resourceful, adaptable, and resilient in the face of numerous dangers while carrying out their vital missions to prepare for amphibious assaults.
