The article analyses the border guard scholars’ views on the algorithmisation and procedure for the use of State Border Guard Service of Ukraine’s assets, as well as the organisation of interaction with the security and defence forces to counteract enemy sabotage and reconnaissance groups on the state border. The article reviews the scientific works on possible options for the use of state border guard units of the state border guard bodies while performing tasks related to state border protection and defence. It is established that the protection of the state border of Ukraine under current conditions is carried out under the legal regime of martial law. The war is ongoing in the East of Ukraine, and the rest of the country has seen a deterioration in the crime situation, and therefore the border guard detachment headquarters must be constantly prepared to work in such circumstances and, particularly, be ready to counteract the enemy’s sabotage and reconnaissance activities. Based on the above, we have identified a number of recommendations for the border guard detachment’s headquarters to organise special measures to search for and eliminate enemy sabotage and reconnaissance groups and to involve the defence forces in these actions. Taking into account the latest risks and threats arising on the state border of Ukraine, as well as the approval of the “Military Security Strategy of Ukrain” perspective directions for further work improvement on ensuring reliable protection and defence of the state border of Ukraine and countering enemy sabotage and reconnaissance groups on the state border are outlined, which can be reflected in the development of a wide range of algorithms for the actions of the head of the state border guard body, for localising situations of various genesis, as well as organizing interaction with units from the security and defence forces of Ukraine.
