Mobile Construction Battalion 7 (MCB-7)

U.S. Army

Mobile Construction Battalion 7 (MCB-7), known as the "Magnificent Seven," was a United States Navy Seabee unit established during World War II in 1942. The battalion played a crucial role in the Pacific Theater, constructing airfields, bases, and infrastructure across islands such as Guadalcanal and Okinawa. After World War II, MCB-7 was decommissioned but was reactivated during the Korean War and later served in Vietnam, building essential facilities and supporting combat operations. Throughout its history, MCB-7 earned a reputation for rapid, high-quality construction under combat conditions before being decommissioned in 1994.
