Personal view: security sector health systems and global health.

In many countries the security sector is a major contributor to the healthcare system. The role and transformation of a state's security health system within the universal health coverage is important, in that it sits at the interface of the United Nations Sustainable Development Goals 3 (ensure healthy lives and promote well-being) and 16 (promote just, peaceful and inclusive societies). The paper describes the breadth of the security sector and outlines the potential beneficiaries, clinical services and macro-organisation of a security sector health system from the perspective of its contribution to wider government health services and crisis response. It examines the characteristics of the security sector compared with other providers of health services, including those generic to the sector and unique to a given service. Understanding civil-security relationships is a critical facet of effective Defence Healthcare Engagement (DHE), which includes the use of defence medical assets in support of capacity-building overseas. The analytical process described may form the basis of DHE planning. It may have even greater importance in the near future as countries review national resilience and global health diplomacy after the COVID-19 crisis.
