5"/25 (12.7 cm) AA guns on USS New Mexico BB-44 in June 1944. Note the fuze setting machines next to each weapon. On the two nearest weapons, note the "Hot Case Man" standing behind the breech and equipped with asbestos "catcher's mitts" gauntlets. Their job was to catch the ejected casing and then toss it out of the way of the gun crew. U.S. Naval Historical Center Photograph # 80-G-K-14162
