*5.3. Structure*

Many of the investigated facilities (PHCC, veterinary, and dental clinics) are suitable for utilization in a FSC-response system. Some are operational presently, while others require a retrofitting e ffort such as preparing bed space, ensuring utilities and wraparound services, and clearing the facility from other operations. Hotels and sports arenas demand a more extensive retrofitting process to ensure adequate operational facility standards for healthcare provision. Countries such as Sweden have historically had little experience of domestic healthcare provision in nonconventional or standardized facilities. Nonetheless, as part of the response to the COVID-19 pandemic, several areas have been explored to increase the capacity of Swedish healthcare [35,37]. In line with the total defense structure, civilian-military collaboration has also increased, and military field hospitals have been deployed to house additional beds outside of major hospitals. The transportation of critical patients has been performed with military helicopters. However, to avoid misunderstanding and to smooth the pace of collaboration, these e fforts should be planned and trained [35].
