In the German army the training of men to do this work (General Staff work) is given only to officers specially selected.

Certain young officers who promise well are sent to the war college.

Those who show aptitude and industry are then put tentatively into the General Staff.

Those who show marked fitness in their tentative employment are then put into the General Staff, which is as truly a special corps as is our construction corps.

How closely this system is followed with the General Staff in the German navy, the present writer does not know exactly; but his information is that the system in the navy is copied (though with certain modifications) after the system in the army.
How can the General Staff at the Navy Department be trained?
In the same way as that in which officers at the war college are trained: by study and by solving war problems by tactical and strategical games.
