What is the common base for odd-numbered units?

The common base for odd-numbered units is Point Loma, California. This location has historically served as a key operational and training center for various Naval Special Warfare units, particularly the Underwater Demolition Teams (UDTs) and the Navy SEALs.

Point Loma's strategic position on the West Coast provided access to the Pacific Theater during World War II and beyond, making it an ideal hub for training and operations. The facilities at Point Loma were specifically designed to support the unique needs of these special warfare units, facilitating advanced training in underwater demolition, reconnaissance, and other specialized skills necessary for their missions.

While other locations mentioned have played significant roles in naval operations, they do not serve as the common base for odd-numbered units. Pearl Harbor, for example, was more prominent during the early years of World War II but is not specifically associated with the odd-numbered units. Guam and Rota, Spain, are also important for various military operations, but they do not serve the same foundational role for the odd-numbered units as Point Loma does.
