U. S. Anti-Aircraft Battery - Shows Teamwork In Action -- This is picture B of the loading sequence. The loader (nicknamed "The Dancer" because of his agility) is laying the round in the breech and the gunner (left) prepares to ram it home with his left fist. The gunner's right hand is reaching for the trigger. Meanwhile, another shell is being passed by the ammunition relayer to have the fuse cut by the automatic cutter, which must be synchronized with must the rangefinder so that the shell will burst at the right height.
