In the last years the focus of the military specialists changed from the asymmetrical threats to the hybrid threats, seen as one of the main challenge for the security in the 21st century. The increased attention paid to hybrid threats is due to the events that took place in Ukraine, Syria and other confrontation areas and which highlighted the vulnerability of the modern societies and modern armies toward this type of actions. The use of hybrid type tactics can ensure the achievement of the main objectives of an international actor, with a low effort, usually without using the force, and can deny to the target/victim the possibility to take any defensive actions. The hybrid warfare can represent the war of the 21st century, a new type of direct or indirect confrontation, with effects on short and medium term, impossible to be anticipated.
