Naval Mobile Construction Battalion 133 (NMCB-133), known as the "Runnin’ Roos," was commissioned on August 17, 1943, during World War II. The battalion earned distinction for its construction and engineering support throughout the Pacific Theater, including pivotal roles in the Philippines and Okinawa campaigns. Post-war, NMCB-133 supported operations during the Korean and Vietnam Wars, providing critical infrastructure, airfield, and base construction. Today, the battalion continues to serve as a vital component of the U.S. Navy Seabees, deploying worldwide in support of both combat and humanitarian missions.
