MCB 7

U.S. Marine Corps

Naval Mobile Construction Battalion SEVEN (MCB 7), known as the "Magnificent Seven," was a unit of the United States Navy Seabees first commissioned during World War II in 1942. The battalion played a crucial role in constructing airfields, bases, and infrastructure across the Pacific Theater, supporting major campaigns such as Guadalcanal and Okinawa. Post-war, MCB 7 was decommissioned and later reactivated for service during the Korean War, the Cold War, and multiple deployments, including Vietnam and the Middle East. Throughout its history, MCB 7 was renowned for its versatility and dedication, supporting both combat operations and humanitarian missions until its final decommissioning in 2012.
