War is an essential part of the social reality inherent in all stages of human development: from the primitive communal system to the present, where advanced technologies and social progress prevail. However, these characteristics do not make our society more peaceful, on the contrary, according to recent research and reality, now the number of wars and armed conflicts have increased, and most of the conflicts have a pronounced local intra-state character. Thus, wars in the classical sense of them go back to the past, giving way to military and armed conflicts. Now the number of soldiers and the big army doesn’t show the opponents strength. What is more important is the fact that people can use technology, the ideological and informational base to win the war. According to the history, «weak» opponent can be more successful in conflict if he has greater cohesion and ideological unity. Modern wars have already transcended the political boundaries of states, under the pressure of certain trends, they are transformed into transnational wars, that based on privatization, commercialization and obtaining revenue. Thus, the present paper will show a difference in understanding of terms such as «war», «military conflict» and «armed conflict». And also the auteurs will tell about the image of modern war and forecasts for its future transformation.
