This chapter examines the role of the Danish Defence in responding to the COVID-19 pandemic, focusing on the first eight months of 2020. It analyzes the military’s domestic deployment under Denmark’s constitutional and legislative framework, highlighting how armed forces supported civilian authorities through logistics, transportation, quarantine facilities, and crisis management. The study explores challenges in coordination, particularly the military’s adaptation to ad hoc crisis structures and its integration with civilian agencies. It also discusses the securitization of the pandemic in political discourse and the implications for civil-military relations, oversight, and public perception. Lessons include the need for improved crisis planning, inter-agency cooperation, and the military’s role in national emergency preparedness. The chapter concludes that while Danish Defence deviated from established protocols, its flexibility contributed to an effective national response to the pandemic.
