In the wake of an ever-increasing global demand for security over recent years, a number of PMSCs have been created. It is recognized that the supervision and control over the activities of PMSCs so far has been inconsistent. However, the international community and the industry have worked to develop principles of employment and have established a framework for self-regulation. The world is evolving in a way that PMSCs, in combat or in non combat roles, will be present and active whether it is desired or not. It is recognized that PMSCs can be a force multiplier in combat, in a COIN environment, or as part of a nation-building strategy. Once the international legal framework is in place, PMSCs, the private sector, and nation states will benefit from a better understanding of each other s roles and how they can manage security challenges in the future.
