At the end of May, the Council of the European Union adopted 11 new projects and welcomed Denmark as a new member state of the Permanent Structured Cooperation (PESCO) initiative (European Council, 2023). These events are milestones for two reasons; first, these new operations have a focus on interoperability; and second, Denmark’s accession itself, as in the past the country was reluctant to join PESCO and European defence efforts. The 11 new projects focus on a range of military domains. These include training, land, maritime, air systems and cyber. More specifically, the projects concerning land interoperability will primarily focus on unmanned ground systems, communication and infrastructure networks (PESCO, 2023).
