People are different in their way of being. Some differ according to their origin, race, spoken language, nationality, and other criteria, and others differ according to their ambitions, that is, according to their wishes and visions of the future. Some wishes or visions of the future can be obtained in a short way, but others are more difficult to obtain. Thus, in order to achieve their visions and goals, some people resort to military attacks, which turn into a battlefield. These struggles are carried out in serious violation of all the values of human society. A regrettable part of these fights is the participation of mercenaries in these illegal activities. Therefore, in the present scientific approach, we propose to analyze the participation role of mercenaries on the battlefield.
