This document discusses the growth of the private military and security company (PMSC) industry, with a focus on British companies. It notes that the UK is a major hub for PMSCs, with hundreds operating globally. Many British PMSCs are large corporations dominated by former military personnel. Iraq was a major incubator for the industry following the 2003 invasion, and British PMSCs continue to operate there providing security for governments and oil companies. The industry is also expanding into Africa to meet demand from extractive companies seeking security in unstable regions.
