This paper analyses four dilemmas implied in the legal regulation of private military and security companies. The dilemmas pertain to whether, and to what extent, it is pertinent to legally regulate PMSCs; on what level the regulation should be adopted; who the subjects of relevant legal norms should be; and what content these norms should be given.
The paper presents possible solutions to the dilemmas, enlisting strong and weak aspects of each of them. It also shows which solutions are embraced by existing legal instruments relating to the activities of PMSCs.
