Naval Mobile Construction Battalion 133 Seabees, Equipment Operator 1st Class Drew Reyes and Construction Mechanic Constructionman Enochlee Umphrey help carry Equipment Operator 3rd Class Kyle Dubay across the finish line during the last day of the command’s Black Hell Squad competition. 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.
