Oil well rigger
Isak Reuben worked and lived in the engine room spaces of USS Walker. He argued that leaving those spaces for fresh air would reduce his ability to stand the intense heat. Before joining the Navy, Reuben and his fellow fireman (and secret half brother), Gilbert Yager, had worked in the oil fields of the United States.
After Walker arrived in the alternate Earth, Reuben and Yager successfully drilled for oil to fuel Walker. Against orders, Reuben participated in the Battle of the Stones.
