A mechanical notion of warfare and weak concessions to the pressure of public opinion, and often a defective grasp of the actual needs, have conduced to measures which inevitably result in an essential contradiction between the needs of the army and the actual end attained, and cannot be justified from the purely military point of view. It would be illogical and irrelevant to continue in these paths so soon as it is recognized that the desired superiority over the enemy cannot be reached on them. This essential contradiction between what is necessary and what is attained appears in the enforcement of the law of universal military service. Opinion oscillates between the wish to enforce it more or less, and the disinclination to make the required outlay, and recourse is had to all sorts of subterfuges which may save appearances without giving a good trial to the system. One of these methods is the _Ersatzreserve_, which is once more being frequently proposed. But the situation is by no means helped by the very brief training which these units at best receive. This system only creates a military mob, which has no capacity for serious military operations. Such an institution would be a heavy strain on the existing teaching _personnel_ in the army, and would be indirectly detrimental to it as well. Nor would any strengthening of the field army be possible under this scheme, since the cadres to contain the mass of these special reservists are not ready to hand. This mass would therefore only fill up the recruiting depots, and facilitate to some degree the task of making good the losses.
