This article examines the presence of 605 armed groups in today's conflict environment by bringing new evidence based on internal research. It looks in particular at the way these non-State entities provide varying degrees of services to the population in the spaces that they control, and how this might impact the way a humanitarian organization like the ICRC engages with them in a dialogue over time. This model of analysis is then used to situate and better explain armed groups’ positions on the COVID crisis.
