U. S. Anti-Aircraft Battery - Shows Teamwork In Action -- After the rangefinder and director station have located the target for accurate firing, the work of the gun crew begins. While part of the eight-man crew aims in accordance with the electrically transmitted instructions, the ammunition carriers and the loader go into action. These three pictures, of which this is a, show the loading. The ammunition relayer at rear has just passed the shell to the second relayer (hand on shell), who has inserted it into the fuse setter and struck the trip leaver with his left hand.
