Inside A "Hell Buggy" -- Tank men launch when submarine crews talk of cramped quarters. They wonder how the Navy men would like to ride in this tank cab, into which four troopers must crowd. It's a steel box full of nasty corners, sharp edges, jagged gear teeth and projecting objects. The helmet, much like that used in football, is the only protection furnished. And there. Swinging an inch over this driver's head is the. 50-caliber gun on its traversing rods. To the right is the. 30-caliber and on the floor at the right of the driver's seat is the humped ridge for the propeller shaft. October 29, 1941. (Photo by ACME).
