Private military company
A private military company (PMC) or  private military and security company (PMSC) is a private company providing armed combat or security services for financial gain. PMCs refer to their personnel as "security contractors" or "private military contractors". The services and expertise offered by PMCs are typically similar to those of governmental security, military, or police but most often on a smaller scale. PMCs often provide services to train or supplement official armed forces in service of governments, but they can also be employed by private companies to provide bodyguards for key staff or protection of company premises, especially in hostile territories. However, contractors that use armed force in a warzone may be considered unlawful combatants in reference to a concept that is outlined in the Geneva Conventions and explicitly stated by the 2006 American Military Commissions Act.The services of private contractors are used around the world.
