The plot of the dissertation deals with the analysis of the prerequisites and methodological principles of studing the Army as the subject of social practice that provides the national security for Ukrainian society in time of its internal transformation. The topicality of the research object is conditioned by the fact that the concept of opposed and multicivilized world defines the appropriate measures for all branches as to ukrainian society, particularly in the context of traditional threats survival (war, aggressions, conflicts), as well as, appearing of new dangers on the way of mankind life's work. Moreover, the indefinition and institutional alienation of the majority interests in the world appear as a result of social system transformatoin. The development of theoretical methodological problems providing national security of Ukraine, the socio-philosophical analysis of the Army's place and aims as a main subject of the Ukrainian peoples base values defence play a particular great role. For a lo ng time, Ukraine didn't have any opportunity to develop and realize its own concept of steady and balanced development and proper national security strategy. The historical experience lack in complex defence of vital national interests blows a negative cloud on the process of overcoming the state desubjectivisation results and impedes the process of its Armed Forces formation. To turn to new quality measures of the contemporary Ukrainian Armed Forces, even not having proper practical and theoretical experience, we are to perfect constantly its concept models according to the scientific programme of the national security provision. It is well-grounded that security as a social phenomenon is one of the necessary man subjectivity being way. It reflects the certain plot of the dependences and relations between the components of society, among them the military power (which is defined by the Armed Forces, first of all) enhances essentially the state survival probability under the sustained threatening conditions o f a traditional character (war, aggression, conflicts), as well as new appearing dangers for steady vital activity. This allows to define the expediency of complex and multilevel social cognition elements employment regarding the possibilities of a "mild" and system methodology of the personal vital interests investigational problems profection (first of all the armed one) as well as social and national interests. The investigation of the Army in socio - philosophical facet as one of the most important subjects of national security providing, makes it possible to define the rising tendency of its influence on the institutional basis of the transforming Ukrainian society under the conditions of reinforcing the civilized confrontation (in sociocultural, informational aspects). It is well - grounded that the subject - object relations play a role of the main criterion for elaboration of the component structure of the social security. The main elements contained in the Ukrainian national security system (where th e Army has sustained its high level status) are the following: the social activity's subjects (personality, social organizations and institutes, first of all); connections and relations between people corresponding the main spheres of the social activity; the certain socio - cultural measures of the vital interests defence subjects (needs, interests, values, the site of the world - outlook). The author's comprehension of wide and narrow sense in the national security is proposed here, basing on the defining of real and potential threats towards personality, society and state in the context of non - coincidence of real natural components to the social development needs, that, in principle, affects the dynamics of its military sphere. The given attitude makes it possible to formulate the comprehension of the essence of the contemporary national Army as a specific social institute of the newly found independent state. It is well - grounded, that the problems of the Army activity optimisation are defined by corre lation of objective conditions and subjective factors of social conflicts generating in the transitional national security providing systems. The main problems of reliable national security provision are solved basing the social activity technology development within which the military sphere measures are synchronized with common transformational changes in the Ukrainian society. They are able to limit the selfish purposefulness and to object the individual activity to the really defined prior national interests. The main concept position of the work is the idea of depending of the state national security provision fidelity upon the national vital interests defence main subjects integral activity and a common process of the peoples' sociocultural reformation.
