Private military company
The examples and perspective in this article may not represent a worldwide view of the subject. (April 2018) (Learn how and when to remove this template message)
A private military company (PMC) is a private company providing armed combat or security services. They are one type of private security companies. PMCs refer to their staff as "security contractors" or "private military contractors". Private military companies refer to their business generally as the "private military industry" or "The Circuit".
The services and expertise offered by PMCs are typically similar to those of governmental security, military or police forces, most often on a smaller scale. While PMCs often provide services to train or supplement official armed forces in service of governments, 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 who use offensive force in a war zone could be considered unlawful combatants, in reference to a concept outlined in the Geneva Conventions and explicitly specified by the 2006 American Military Commissions Act.
The services of private contractors are used around the world. P. W. Singer, author of Corporate Warriors: The Rise of the Privatized Military Industry, says "In geographic terms, it operates in over 50 different countries. It’s operated in every single continent but Antarctica." Singer states that in the 1990s there used to be 50 military personnel for every 1 contractor, and now the ratio is 10 to 1. He also points out that these contractors have a number of duties depending on whom they are hired by. In developing countries that have natural resources, such as oil refineries in Iraq, they are hired to guard the area. They are also hired 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 different missions and jobs. Some examples are supplying bodyguards to the Afghan president Hamid Karzai and piloting reconnaissance airplanes and helicopters as a part of Plan Colombia. According to a study from 2003 the PMC industry was worth over $100 billion a year at that time.
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 budgets.
According to the Brazilian geostrategist De Leon Petta, far from meaning a possible weakening of the national state power and its monopoly on violence, these PMCs will actually serve as alternative forms of power application abroad through irregular means, without violating international law, causing troubles in the domestic or public policy, or too many international repercussions. American scholar Phelps makes a similar claim by finding that PMCs wrap themselves in state governments' "cloak of legitimacy".
Modern PMCs trace their origins back to a group of ex-SAS British veterans in 1965 who, under the leadership of the founder of the SAS, Sir David Stirling and John Woodhouse, founded WatchGuard International (formerly with offices in Sloane Street before moving to South Audley Street in Mayfair) as a private company that could be contracted out for security and military purposes.
The company's first assignment was to go to Yemen to report on the state of the royalist forces when a cease-fire was declared. At the same time Stirling was cultivating his contacts in the Iranian government and exploring the chances of obtaining work in Africa. The company eventually operated in Zambia and in Sierra Leone, providing training teams and advising on security matters. Stirling also organised deals to sell British weapons and military personnel to other countries for various privatised foreign policy operations. Contracts were mainly with the Gulf States and involved weapons supply and training. The company was also linked with a failed attempt to overthrow Colonel Muammar Gaddafi from power in Libya in 1971. Woodhouse resigned as Director of Operations after a series of disagreements and Stirling himself ceased to take an active part in 1972.
Stirling also founded KAS International (aka KAS Enterprises) and was involved in a collaboration with the WWF to forcibly reduce the illegal poaching and smuggling of elephant tusks in various countries of Southern Africa. Other groups formed by ex-SAS servicemen were established in the 1970s and 80s, including Control Risks Group and Defence Systems, providing military consultation and training.
Dramatic growth in the number and size of PMCs occurred at the time of the end of the Cold War, as Western governments increasingly began to rely on their services to bolster falling conventional military budgets. Some of the larger corporations are: Vinnell and Military Professional Resources Inc. in the United States; G4S and Keeni-Meeny Services in the United Kingdom; Lordan-Levdan in Israel and Executive Outcomes in South Africa.
The exodus of over 6 million military personnel from Western militaries in the 1990s expanded the recruiting pool for PMCs.
Some commentators have argued that there was an exodus from many special operations forces across the globe towards these private military corporations. Units that were allegedly severely affected included the British Special Air Service, the US Special Operations Forces and the Canadian Joint Task Force 2. Finding work in the industry is not difficult for most former soldiers as their personal network of fellow and ex-soldiers is enough to keep them informed of available contracts.
In 1985, Logistics Civil Augmentation Program (LOGCAP) was established in the United States, primarily to preplan for contingencies and to leverage the existing civilian resources. However, it was three years later before it was first used. In support of a United States Third Army mission, the United States Army Corps of Engineers (USACE) used LOGCAP to contract for the construction and maintenance of two petroleum pipelines systems in Southwest Asia.
Later, USACE awarded the first contract under LOGCAP to Brown and Root Services (now KBR) in August 1992 as a cost-plus-award-fee contract, which was used in December that year to support the United Nations forces in Somalia.
Some contractors have served in advisory roles, that help train local militaries to fight more effectively, instead of intervening directly. Much of the peacekeeper training Western governments have provided to African militaries was done by private firms, and with the increasing absence of Western military support to international peace operations, the private sector was commonly utilized to provide services to peace and stability operations from Haiti to Darfur.
The Center for Public Integrity reported that since 1994, the Defense Department entered into 3,601 contracts worth $300 billion with 12 U.S. based various PMCs within the United States, specifically during the initial response after Hurricane Katrina in New Orleans.
Domestic operations are generally under the auspice of state or federal agencies such as the Department of Energy or the Department of Homeland Security rather than the Department of Defense. Driven by increasingly greater fears of domestic terror attacks and civil unrest and disruption in the wake of disasters, more conventional security companies are moving into operations arenas that would fall within the definition of a PMC. The United States State Department also employs several companies to provide support in danger zones that would be difficult for conventional U.S. forces.
PMCs in IraqEdit
In August 2003 Close Protection operatives from a United Kingdom based security and intelligence company International Intelligence Limited rescued six British lawyers from a hostile crowd in Baghdad, extracting them to a neutral hotel, in a pro bono action despite those solicitors not being clients of the firm.
In December 2006, there were estimated to be at least 100,000 contractors working directly for the United States Department of Defense in Iraq which was a tenfold increase in the use of private contractors for military operations since the Persian Gulf War, just over a decade earlier. The prevalence of PMCs led to the foundation of trade group the Private Security Company Association of Iraq. In Iraq, the issue of accountability, especially in the case of contractors carrying weapons, was a sensitive one. Iraqi laws do not hold over contractors.
U.S. Secretary of Defense Donald Rumsfeld justified the use of PMCs in Iraq on the basis that they were cost effective and useful on the ground. He also affirmed that they were not subject to the Uniform Code of Military Justice.
Two days before he left Iraq, L. Paul Bremer signed "Order 17" giving all Americans associated with the CPA and the American government immunity from Iraqi law. A July 2007 report from the American Congressional Research Service indicates that the Iraqi government still had no authority over private security firms contracted by the U.S. government.
PMCs supplied support to U.S. military bases throughout the Persian Gulf, from operating mess halls to providing security. They supplied armed guards at a U.S. Army base in Qatar, and they used live ammunition to train soldiers at Camp Doha in Kuwait. They maintained an array of weapons systems vital to the invasion of Iraq. They also provided bodyguards for VIPs, guard installations, and escort supply convoys from Kuwait. All these resources were called upon constantly.
- Employees of private military company CACI and Titan Corp. were involved in the Iraq Abu Ghraib prison scandal in 2003, and 2004. The U.S. Army "found that contractors were involved in 36 percent of the [Abu Ghraib] proven incidents and identified 6 employees as individually culpable", although none have faced prosecution unlike US military personnel.
- On March 31, 2004, four American private contractors belonging to the company Blackwater USA were killed by insurgents in Fallujah as they drove through the town. They were dragged from their car in one of the most violent attacks on U.S. contractors in the conflict. Following the attack, an angry mob mutilated and burned the bodies, dragging them through the streets before they were hung on a bridge. (See also: 31 March 2004 Fallujah ambush, Operation Vigilant Resolve)
- On March 28, 2005, 16 American contractors and three Iraqi aides from Zapata Engineering, under contract to the US Army Corps of Engineers to manage an ammunition storage depot, were detained following two incidents in which they allegedly fired upon U.S. Marine checkpoint. While later released, the contractors have levied complaints of mistreatment against the Marines who detained them.
- On June 5, 2005, Colonel Theodore S. Westhusing committed suicide, after writing a report exonerating US Investigations Services of allegations of fraud, waste and abuse he received in an anonymous letter in May.
- On October 27, 2005, a "trophy" video, complete with post-production Elvis Presley music, appearing to show private military contractors in Baghdad shooting Iraqi civilians sparked two investigations after it was posted on the Internet. The video has been linked unofficially to Aegis Defence Services. According to the posters, the man who is seen shooting vehicles on this video in Iraq was a South African employee of Aegis Victory team named Danny Heydenreycher. He served in the British military for six years. After the incident the regional director for Victory ROC tried to fire Heydenreycher, but the team threatened to resign if he did. Aegis, the U.S. Army, and the U.S. State Department each conducted a formal inquiry into the issue. The Army determined that there was no "probable cause to believe that a crime was committed."
- On September 17, 2007, the Iraqi government announced that it was revoking the license of the American security firm Blackwater USA over the firm's involvement in the deaths of seventeen Iraqis in a firefight that followed a car bomb explosion near a State Department motorcade. However, the company was allowed to continue to operate in Iraq until January 2009 when the U.S.–Iraq Status of Forces Agreement took effect. Blackwater was one of the most high-profile firms operating in Iraq, with around 1,000 employees as well as a fleet of helicopters in the country. In 2014, four Blackwater employees were tried and convicted in U.S. federal court over the incident; one of murder, and the other three of manslaughter and firearms charges.
- Sallyport Global-May 3, 2017 report of Sallyport Global conduct in Iraqi 
By the end of 2012, the number of contractors who had died in Iraq, Afghanistan and Kuwait had reached 3,000. Scholars have studied whether contractor deaths have an effect the public's "casualty sensitivity" when substituted for military fatalities. Casualty sensitivity refers to the inverse relationship between military deaths and public support for a sustained military engagement. Contractor deaths may account for nearly 30% of total US battlefield losses since the beginning of the wars in Iraq and Afghanistan.

International legal issuesEdit
In October 2007, the United Nations released a two-year study that reported, that although hired as "security guards", private contractors performed military duties. Many countries, including the United States and the United Kingdom, are not signatories to the 1989 United Nations Mercenary Convention banning the use of mercenaries. However, a spokesman for the American mission to the U.N. office in Geneva (UNOG) said that "Accusations that U.S. government-contracted security guards, of whatever nationality, are mercenaries is inaccurate." As Martha Lizabeth Phelps points out, the difficulty separating private from public troops means that legal proceedings against these non-state violent actors can be complicated. She claims contracted combatants carry the legitimacy of the state that hires these firms. There is currently no globally accepted norms or legal framework applied to these firms.
The corporate nature of PMSCs (Private Military and Security Contractors) is a barrier to their accountability for violations of international law (Crow & John, 2017). No international court has jurisdiction over these corporations and there is no preexisting mechanism in place bound by international law to account and manage for PMSCs use of force. However, there are a few soft law instruments in which these corporations are held responsible to some degree of legal status. One favorable argument for PMSCs is that they have the skills and expertise necessary to deploy in a short times notice with the ability to provide for a wide range of services (Malamud, 2014). However, outsourcing does bring on the risk of a lack of transparency in the selection process of third party personnel. In addition, the UN is held responsible to ensure a clean human rights record and maintaining a gold standard for missions that entail the use of private contractors. Often, states do not have control over these operations. In many cases, there are doubts to as if the work of private contractors does or does not fall within the boundaries of Article 47 of the Protocol Additional to the Geneva Conventions of 1949, as well as relating to the Protections of International Armed Conflicts 1977 amongst others (Karska & Karski, 2014). Although, in 2012 the UN Department of Safety and security published a new policy in which oversees the use of armed private contractors. Planning is also underway at the United Nations to prepare a convention dealing with PMSCs. Establishing clear criteria is necessary to determine when it is permissible to use such companies and for what activities. Criteria such as transparent decision making procedures, solid vetting and screening measures, as well as standard operating procedures. Private military and security firms provide a temporary mechanism for countries with prolonged violence and security unrest.
PMC activities elsewhereEdit
- In 1994 and 1995 South African based PMC Executive Outcomes was involved in two military actions in Africa. In the first conflict, EO fought on the behalf of the Angolan government against UNITA after a UN brokered peace settlement broke down. In the second action EO was tasked with containing a guerrilla movement in Sierra Leone called the Revolutionary United Front. Both missions involved personnel from the firm training four to five thousand combat personnel for the Angolan government and retaking control of the diamond fields and forming a negotiated peace in Sierra Leone.
- In 1995, both Croatia and Bosnia hired Military Professional Resources Inc. ( M.P.R.I. ) to equip, train and professionalize their armed forces.
- In 1999, an incident involving DynCorp in Bosnia was followed by a Racketeer Influenced and Corrupt Organizations Act (RICO) lawsuit being filed against DynCorp employees stationed in Bosnia. It alleged that: "employees and supervisors from DynCorp were engaging in perverse, illegal and inhumane behavior and were illegally purchasing women, weapons, forged passports and participating in other immoral acts."
- In 2000, the Australian Broadcasting Corporation's ABC Television international affairs program "Foreign Correspondent" broadcast a special report "Sierra Leone: Soldiers of Fortune", focusing on the exploits of South African pilot Neall Ellis and his MI-24 Hind gunship. The report also investigated the failures of the UN Peacekeeping Force, and the involvement of mercenaries/private military contractors in providing vital support to UN operations and British military Special Operations in Sierra Leone in 1999-2000.
- On April 5, 2005, Jamie Smith, CEO of SCG International Risk announced the expansion of services from the traditional roles of PMCs of protection and intelligence to military aviation support. SCG International Air would provide air support, medevac (medical evacuation), rotary and fixed-wing transportation, heavy-lift cargo, armed escort and executive air travel to "any location on earth." This marked a unique addition and expansion of services to rival the capabilities of some country's armies and air forces.
- On March 27, 2006, J. Cofer Black, vice chairman of Blackwater USA announced to attendees of a special operations exhibition in Jordan that his company could now provide a brigade-size force for low intensity conflicts. According to Black, "There is clear potential to conduct security operations at a fraction of the cost of NATO operations". These comments were later denied.
- In mid-May 2006, police in the Democratic Republic of the Congo arrested 32 alleged mercenaries of different nationalities; 19 South Africans, 10 Nigerians and three Americans. Half of them worked for a South African company named Omega Security Solutions and the Americans for AQMI Strategy Corp. The men were accused of plotting to overthrow the government but charges were not pressed. The men were deported to their home countries.
- In 2006, a U.S. congressional report listed a number of PMCs and other enterprises that have signed contracts to carry out anti-narcotics operations and related activities as part of Plan Colombia. DynCorp was among those contracted by the State Department, while others signed contracts with the Defense Department. Other companies from different countries, including Israel, have also signed contracts with the Colombian Defense Ministry to carry out security or military activities.
- In December 2009, the Congressional Research Service, which provides background information to members of the United States Congress, announced that the deployment of 30,000 extra U.S. troops into Afghanistan could be accompanied by a surge of "26,000 to 56,000" contractors. This would expand the presence of personnel from the U.S. private sector in Afghanistan "to anywhere from 130,000 to 160,000". The CRS study said contractors made up 69 percent of the Pentagon's personnel in Afghanistan in December 2008, a proportion that "apparently represented the highest recorded percentage of contractors used by the Defense Department in any conflict in the history of the United States." In September 2008 their presence had dropped to 62 percent, while the U.S. military troop strength increased modestly.
- Also in December 2009, a House oversight subcommittee said that it had begun a wide-ranging investigation into allegations that American private security companies hired to protect Defense Department convoys in Afghanistan would be paying off warlords and the Taliban to ensure safe passage. That would mean that the United States unintentionally and indirectly engaged in a protection racket and may be indirectly funding the very insurgents it is trying to fight. A preliminary inquiry determined that the allegations warranted a deeper inquiry, focused initially on eight trucking companies that share a $2.2 billion Defense Department contract to carry goods and material from main supply points inside Afghanistan (primarily Bagram air base) to more than 100 forward operating bases and other military facilities in the country.
- In 2015, STTEP International, (Specialised Tasks, Training, Equipment & Protection) was credited with providing support to the Nigerian military that has proved decisive in containing Boko Haram activities in Nigeria. The chairman of STTEP, Eeben Barlow, is the former CEO and founder of Executive Outcomes.
Relation to non-governmental organizationsEdit
The rare use of private security contractors by NGOs in dangerous regions is a highly sensitive subject. While rare, many NGOs have sought the services of private security contractors in dangerous areas of operation, such as Afghanistan, Somalia and Sudan due to the following reasons:
- Lack of knowledge/skills and time to adequately meet the challenges of deteriorating security environments; and
- Administrative costs of managing security in-house and potential to outsource the liability.
Quite often the contractors hired are local companies and mostly are unarmed personnel guarding facilities, only very rarely are international contractors or mobile armed security personnel used.
|Contracted security services used by humanitarians||% of organizations contracting from international PSPs||% organizations contracting from local PSPs|
|Unarmed guards for facilities/residences/project sites||29%||77%|
|Physical security for premises||31%||55%|
|Security management consulting||37%||9%|
|Security training for staff||41%||4%|
|Risk assessment/threat analysis||36%||7%|
|Armed guards for facilities/residences/project sites||17%||14%|
|Mobile escorts (armed)||9%||13%|
However, there are a great many voices against their use who cite the following problems:
- Outsourcing security left NGOs reliant on contractors and unable to develop their own security thinking and make their own decisions
- Perceived association of PSPs with state security, police or military services in turn compromises the ability of NGOs to claim neutrality, leading to increased risk;
- Outsourcing may not necessarily lead to lower costs, and the cost of middlemen may result in more poorly paid and poorly trained personnel who turn over frequently and cannot adequately perform the job; and
- NGOs have obligations beyond strictly legal liability that include political, ethical and reputational implications - if the organisation’s responsibility to prevent and mitigate any possible negative outcomes is better achieved through in-house security, this should be their choice.
The result is that many NGOs are not open about their use of PSPs and researchers' at the Overseas Development Institute studies have found that sometimes statements at NGOs central headquarters contradict those given by local staff. This prevents informative knowledge-sharing and debate on the subject needed to improve NGOs decisions regarding this issue, though there have been some notable exceptions (Afghanistan NGO Security Office (ANSO) and the NGO Coordination Committee in Iraq (NCCI)). The Private Security Contractor fulfills many different needs in the private and public sectors. While some nations rely heavily on the input of governments such as the US, other countries do not trust the US, so they tend to look for private contractors who will have a fiduciary obligation them. According to Joel Vargas, Director of Operations for Contingent Security Services, Ltd and Assistant Director for InterPort Police, it will be impossible to build democracies without having the assistance from the private sector performing activities for clients.
After the withdrawal of US troops from Iraq, the U.S. State Department is reportedly planning to more than double the number of its private security guards, up to as many as 7,000. Defending five fortified compounds across the country, the security contractors would operate radars to warn of enemy rocket attacks, search for roadside bombs, fly reconnaissance drones and even staff quick reaction forces to aid civilians in distress. The State Department plans to acquire 60 mine-resistant, ambush-protected vehicles (MRAPs) from the US military to expand its inventory of armored cars to 1,320 and to create a mini-air fleet by buying three planes to add to its lone aircraft. Its helicopter fleet, which will be piloted by contractors, will grow from 17 to 29.
Due to strain of United States Armed Forces, the U.S. State Department and The Pentagon has also outsourced the expanded military training in Africa to three companies: Military Professional Resources Inc. (M.P.R.I), DFI International and Logicon (Now owned by Northrop Grumman).
Demands for specific PSC services have grown to record levels in recent decades, and private firm’s capabilities now include an array of services that are vital to the success of on-the-ground war fighting as well as other more traditional stability operations and contingency contracting. While past calls for corporate responsibility have heralded successes such as the Kimberley Process and the Extractive Industries Transparency Initiative in widespread international operations, there has also been a move within the PSC and contingency contracting industries to call for accountability and to implement a code of ethics for the retention of services and operations of such service providers. Existing credible accountability initiatives form a skeleton for governing the conduct of contractors, but much remains to be fleshed out to form a coherent and standardized framework from which to oversee such organizations and activities. Over the last decade there have been a number of initiatives to regulate the private security industry. These include the ISO/PAS 28007:2012 Guidelines for Private Maritime Security Companies and the ANSI/ASIS PSC.1 and PSC.4 standards.
ASIS Commission on StandardsEdit
Founded in 1955, ASIS is a society of individual security professionals dedicated to increasing the effectiveness and productivity of security professionals by developing educational programs and materials. ASIS is an ANSI-accredited Standards Developing Organization, and within ASIS the ASIS Commission on Standards and Guidelines works with national and international standards-setting organizations and industry representatives to develop voluntary standards and guidelines for security professionals. With funding from the U.S. Department of Defense, the ASIS Commission on Standards is currently promulgating four sets of standards for private security companies.
PSC.1 - MANAGEMENT SYSTEM FOR QUALITY OF PRIVATE SECURITY COMPANY OPERATIONS-REQUIREMENTS WITH GUIDANCE This Standard provides auditable criteria for quality assurance of Private Security Company (PSC) operations and services, consistent with pertinent legal and human rights obligations and good practices recognized in the Montreux Document and the International Code of Conduct for Private Security Service Providers. The development of this Standard was facilitated by the U.S. Department of Defense through a consensus-based process. The DOD was required by Congress through Section 833 of the National Defense Authorization Act of 2011 to begin using business and operational standards in contracting and management of PSCs, with the intent of raising the overall standard of performance of these companies. This Standard fulfills that mandate. It has also been recognized by the American National Standards Institute and are achieving international recognition.
PSC.2 - CONFORMITY ASSESSMENT AND AUDITING MANAGEMENT SYSTEMS FOR QUALITY OF PRIVATE SECURITY COMPANY OPERATION This Standard provides requirements and guidance for conducting conformity assessment of the Management System for Quality of Private Security Company Operations (PSC) Standard. It provides requirements for bodies providing auditing and third party certification of Private Security Company Operations - private security providers working for any client. It provides requirements and guidance on the management of audit programs, conduct of internal or external audits of the management system and PSC operations, as well as on competence and evaluation of auditors.
PSC.3 - MATURITY MODEL FOR THE PHASED IMPLEMENTATION OF A QUALITY ASSURANCE MANAGEMENT SYSTEM FOR PRIVATE SECURITY SERVICE PROVIDERS Standard PSC.3 development is complete and has been approved in January 2013. PSC.3 will benefit private security service providers in improving their quality of services consistent with respect for human rights and legal and contractual obligations. It will provide a basis for managing risk while reducing costs, demonstrating legal compliance, enhancing stakeholder relations, and meeting client expectations. The model standard outlines six phases ranging from no process in place for quality assurance management, to going beyond the requirements of the standard. Criteria based on core elements of ANSI/ASIS PSC.1-2012 Standard can be used to demonstrate continual improvement and are compatible with rewards and recognition programs.
PSC.4 - QUALITY ASSURANCE AND SECURITY MANAGEMENT FOR PRIVATE SECURITY COMPANY'S OPERATING IN THE MARITIME ENVIRONMENT This Standard provides guidance for PMSCs to implement the ANSI/ASIS PSC.1-2012 for private maritime security companies. It establishes guidance on quality assurance in all security related activities and functions while demonstrating accountability to law and respect for human rights.
In 2008, the International Committee of the Red Cross, the Swiss government, and contributors from private security companies and the civil society/NGO sector developed and proposed the Montreux Document on Private Military and Security Companies. The document details international legal obligations and lists specific recommendations related to PSC services procurement practices and operational oversight, and clarifies the obligations of States pertaining to the hiring of such entities during armed conflicts.
PMCs in fictionEdit
In video gamesEdit
Private military companies are explored extensively in the Metal Gear video game franchise, with several games (particularly Metal Gear Solid: Peace Walker, Metal Gear Solid IV: Guns of the Patriots, and Metal Gear Solid V: The Phantom Pain) featuring the command of fictional PMCs. In the video game storyline, which takes place in the 20th and 21st centuries, traditional militaries eventually collapse as the world becomes run by PMCs.
