A specific consideration of the complex of theoretical and practical problems connected with the relations between the art of war and the other militarily orientated branches of science. Problems of these relations are by the author explicated in two ways. He points out, on one hand, the necessity of existence of ties and relations between sciences and branches of sciences, and on the other hand the epistemological problems encountered in identification of these ties and relations, and in valid explication of directions and intensity of their manifestation and powerful practical impacts. Practical problem are, in the author's opinion, manifold. The fundamental ones are those that pertain to the alarmingly irregular relation between this science and the other above mentioned branches of science in matters of personnel and material assets, in matters of personnel this relation is for the art of war very unfavorable. Analyzes of such a state of affairs made from the Symposium on military science (1970) to date show very unfavorable tendencies and gradual shifting of the art of war from its position of a fundamental (and in the author's opinion the only one) military science towards its marginal influence within the so called system of military sciences. This unfavorable relation in matters of personnel directly resulted in unfavorable material relations. These relations are by the author analyzed as the comparative ratio between the accomplished scientific research tasks and the considerably smaller financial means allotted for these tasks. In the end the author gives certain recommendations and proposes measures that would contribute to a more successful solution of the problems mentioned above.
