The controversial involvement of the Wagner Group in Ukraine and Russia’s domestic politics has recently shed light on Private Military and Security Companies (PMSCs). Before that, the American PMSC Blackwater, now Academi, also drew public attention for misconduct during its involvement in Iraq (Singer, 2007). While outsourcing defence and security tasks to private actors by public authorities dates back centuries, PMSCs are a strictly post-Cold War trend (Singer, 2003).
