In which theater were NCDUs transferred after significant losses during Operation OVERLOAD?

The correct context here is that the Naval Combat Demolition Units (NCDUs) faced significant losses during Operation OVERLOAD, which was part of the Normandy landings in World War II. After these losses, the NCDUs were transferred to the Pacific Theater. This decision was influenced by the need for specialized units capable of conducting combat demolition operations in different environments, particularly as the United States focused on the next major offensive against Japanese-held islands.

The Pacific Theater presented unique challenges requiring specialized training, and the NCDUs were instrumental in preparing for operations that involved beach landings and other amphibious assaults in that theater. Their expertise in demolitions and reconnaissance was critical as the U.S. forces advanced through the islands, which underscored the tactical significance of their role in the overall war effort. Thus, the transfer to the Pacific Theater allowed the units to leverage their training and skills in critical future operations.
