The services and expertise offered by PMCs are typically similar to
those of governmental security, military, or police forces 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 convenction and explicitly stated by the 2006 American Military Commissions Act.
The services of private contractors are used around the world. P.Singer, the author of Corporate Warriors: The Rise of the Privatized Military Industry,
stated, "In geographic terms, it operates in over 50 countries. It’s
operated in every single continent but Antarctica." Singer noted that
in the 1990s, there were 50 military personnel for every contractor and
that the ratio is now 10 to 1. He also pointed out that the contractors
have a number of duties, depending on who hires them. In developing
countries that have natural resources, such as oil refineries in Iraq,
they are hired to guard the area. They are hired also to guard companies
that contract services and reconstruction efforts such as General Electric.
Apart from securing companies, they secure officials and
government affiliates. Private military companies carry out many
missions and jobs. Some examples have included close protection for Afghan President Hamid Karzai and piloting reconnaissance airplanes and helicopters as a part of Plan Colombia. According to a 2003 study, the industry was then worth over $100 billion a year.
According to a 2008 study by the Office of the Director of National intelligence, private contractors make up 29% of the workforce in the United States Intelligence Community and cost the equivalent of 49% of their personnel budge.
