If the main guns of battleships in World War II were all radar-guided, what operations did the personnel in the main turret need besides loading ammunition?

The main guns of World War II battleships used radar or shooting directors.

In the later stage of the development of the battleship, the magazine elevator lifted the magazine from the ammunition room (isolated from the turret) to the turret, the magazine loader supported the magazine to the ammunition conveying line, hooked the magazine, the wedge gun machine automatically locked the gun bore or rotated the gun machine, the mechanical device automatically set the fuse and charge, and the shooting data was measured and set by the shooting director. Man's main function is to make the gun have various shooting modes (such as shooting director's injury, etc.). ), and he is mainly responsible for the connection and linkage of artillery at ordinary times, so that the artillery can "obey" the command of the shooting director.
