On the last day of the Black Hell Squad competition, Naval Mobile Construction Battalion 133 Seabees perform a 5 kilometer aid and litter run, carrying their squad leader while in full gear. The competition is homage to the 133rd NCB who joined the Fifth Marine Amphibious Corps and the Fourth Marine Division for the amphibious assault on Iwo Jima. The 133rd had 370 casualties, more than 40 percent of the 875 men that landed, the highest casualties as part of a single battle in Seabee history.
