MCB-3

Naval Mobile Construction Battalion THREE (MCB-3), known as the "Better Than Best," is a distinguished unit of the United States Navy Seabees. Commissioned in 1942, MCB-3 played a vital role in World War II, constructing airfields, bases, and infrastructure across the Pacific theater, including Guadalcanal and Okinawa. The battalion continued its service in subsequent conflicts, notably supporting operations during the Korean and Vietnam Wars by building critical facilities under combat conditions. In peacetime and during humanitarian missions, MCB-3 has provided engineering support and disaster relief worldwide, exemplifying the Seabees’ motto, "We Build, We Fight."
