Since the summer of 2021, the Polish-Belarusian border has become a stage for a migration crisis orchestrated by the Belarusian government. To detain the crisis, the Polish government deployed a range of security actors, including the Border Guard, the military and the police. It effectively launched a spectacle comprising securitised practices of invisibilisation, expulsion, containment and control directed at immigrants, as well as activists, journalists, politicians and other actors attempting to enter the zone. This chapter unravels the militarised mode of border management and focuses on the use of the Territorial Defence Forces (TDF) as one of the key security actors deployed by the Polish government. The chapter uses Goffman’s dramaturgic perspective to investigate specific frames of border management by looking at the way the TDF has presented itself and its involvement in the crisis on social media. This will provide a deeper perspective into practices and discourses of legitimisation of military presence not only on the Polish eastern border but also on the external border of the European Union.
