About MCB8

Naval Mobile Construction Battalion EIGHT (MCB 8), also known as "The Eight Ball Battalion," was a United States Navy Seabee unit originally commissioned during World War II in 1942. The battalion played a vital role in constructing airfields, roads, and bases throughout the Pacific Theater, including operations in Guadalcanal, New Guinea, and the Philippines. After World War II, MCB 8 was decommissioned but later reactivated, serving with distinction during the Korean War and the Vietnam War, where they supported combat operations with critical construction and engineering projects. The unit was finally decommissioned in 1969, leaving behind a legacy of service, adaptability, and engineering excellence.
