MCB-133

Naval Mobile Construction Battalion 133 (MCB-133), also known as the "Runnin' Roos," was commissioned on February 17, 1944, during World War II as part of the U.S. Navy Seabees. The battalion played a crucial role in constructing airfields, bases, and infrastructure across the Pacific theater, including operations in Guam and Okinawa. In the decades following WWII, MCB-133 participated in numerous deployments during the Korean and Vietnam Wars, supporting both combat and humanitarian missions. The unit continued to serve in peacetime operations, disaster relief, and overseas contingency deployments until its decommissioning in 2005.
