Counteracting terrorism should be treated as a complex set of actions. It consists of a recognizable system of factors of a functional and institutional nature. It includes particular groups of activities of services participating in international cooperation in the fight against terrorism: 1) diagnosis, 2) prevention, 3) fight, 4) prosecution and punishment. The contemporary dimension and nature of terrorist threats requires taking into account the security of administrative space and public order, the territory of the country and the threat to military forces, including specialist services. However, the current regulations define the activities of the Polish Military Forces, based on the activities of: 1) military police and other military units; 2) independent activity or in cooperation with the police (more precisely, supporting the police); 3) cooperation with police units and subunits of the Polish military forces and military police; 4) the impact of the activities on the general principles of conduct or principles assumed in the event of an emergency; 5) territorial threat and beyond. For each of the above, there are specific regulations that define in detail the legal framework and the content of anti-terrorist activities. The role of specialized units may be independent. In the current legal situation in Poland, the role of the military is to lead other state services to counteract threats at home and abroad.
