This paper attempts to present an examination of the ethical/normative ramifications involved with the growing use of private military and security companies, provide some original insight, and probe the question of the degree to which potential regulatory efforts can effectively address the nature of the moral concerns thereby raised. The implications examined focus mainly on relevant principles and concepts of the just war tradition and how they relate to the issue of state control over military action, as well as the ethical/political consequences of public accountability and democratic control over force. The paper concludes that the use of private military force is currently still inconsistent with well-established ethical norms to a significant degree, perhaps one that cannot be easily overcome through legal instruments without a corresponding shift in the ethics of warfare itself.
