Name a notable UDT operation in the Pacific theater besides Normandy.

Operation Galvanic stands out as a notable Underwater Demolition Team (UDT) operation in the Pacific theater during World War II. Launched in November 1943, this operation focused on the assault and capture of the Gilbert Islands, specifically Tarawa. The UDT's role was critical in this operation as they conducted reconnaissance, demolition of obstacles, and facilitated beach landings to ensure the success of the subsequent Marine assaults.

The context surrounding the choice reveals that while Normandy and operations like Overlord (the overarching campaign for D-Day) were significant in the European theater, and Neptune was specifically part of the Normandy landings, Galvanic is directly tied to important amphibious operations in the Pacific. Operation Market Garden, on the other hand, was primarily a land operation in the Netherlands, thus not relevant to the UDT's operations in the Pacific.
