To do this successfully, it must be realized, of course, that the greatest single factor in exciting interest is the personal factor, since comparatively few men can get much interested in a matter that is impersonal; a boy is more interested in watching a baseball game in which he knows some of the players than in watching a game between teams neither of which he has ever seen; and the men in any ship are more interested in the competition between their ship and some other than between any other two; feeling that _esprit de corps_ by reason of which every individual in every organization personifies the organization as a living thing of which he himself is part. _Strategic Problems_.--The training of the fleet, then, can best be done under the direction of a trained staff, that staff generously employing all the resources of competition, chance, and danger. The obvious way to do this is to give out to the fleet for solution a continual succession of strategic problems, which the entire fleet will be engaged in solving, and which will be the starting-point for all the drills of the fleet and in the fleet. (Some officers prefer the word "maneuver" to "problem.") The arranging of a continual series of war problems, or maneuvers to be worked out in the fleet by "games," will call for an amount of strategical skill second only to the skill needed for operations in war, will deal with similar factors and be founded on similar principles. Naturally, the war problems, before being sent to the fleet for solving, would be solved first by the staff, using strategical and tactical games, and other appropriate means; and inasmuch as the scheme of education and training is for the benefit of the staff itself, as well as for the benefit of the fleet, certain members of the staff would go out with the fleet to note in what ways, each problem sent down was defective, in what ways good--and in what ways it could be modified with benefit. The successive situations and solutions, made first by the staff and subsequently by the fleet, can then be photographed and made part of the history of war problems, for the library of the staff. In laying out the war problems, the staff will be guided naturally by the ends in view--first to work out solutions of strategic, logistic, and tactical situations in future wars, and second to give opportunity to the various divisions, ships, turret crews, engineers' forces, etc., for drills that will train them to meet probable contingencies in future wars.
