The disarmament, demobilization, and reintegration of excombatants has become an integral part of peacebuilding. Although the main purpose of such interventions is to dissolve the military structures of armed groups, there is growing evidence that ex-combatant networks often remain intact. We investigate why such structures continue to thrive. We argue that ex-military networks are stronger when ex-commanders have weak links to elite patronage systems. Ex-combatants who are unable to rely on their former superiors for economic assistance must instead build denser ties to each other to gain access to a social safety net. To assess our argument, we conduct a comparative social network analysis (SNA) of two ex-military networks in Liberia. This innovative approach helps us uncover previously overlooked, but central, dynamics related to ex-combatant groups. We thereby show that SNA provides a range of underutilized tools and exact definitions that can increase our understanding of ex-military networks.
