Private Military Companies
Read 1 of 6
The rise of private military and security companies and what their growing role means for accountability, sovereignty, and the future of warfare.
The use of hired fighters is as old as warfare itself. Ancient Greek city-states, Renaissance Italian princes, and colonial empires all employed mercenaries. But the modern private military company (PMC) is something different: a corporate entity that provides military and security services for profit, operating with contracts, corporate structures, and sometimes even stock market listings.
The modern PMC industry exploded after the Cold War. Downsized militaries shed experienced soldiers who entered the private sector, while governments facing new security challenges found it convenient to outsource. Executive Outcomes, a South African firm staffed largely by apartheid-era special forces veterans, became famous in the 1990s for its interventions in Sierra Leone and Angola, where its operatives defeated rebel forces that UN peacekeepers had failed to contain. The firm demonstrated that small numbers of well-trained private soldiers could be militarily decisive.
The US wars in Iraq and Afghanistan supercharged the industry. At the peak of the Iraq War, private contractors outnumbered US military personnel in the country. Blackwater (later renamed Xe Services, then Academi) became the most prominent and controversial PMC. Its operatives guarded US diplomats, trained local forces, and conducted security operations. In September 2007, Blackwater guards killed 17 Iraqi civilians at Nisour Square in Baghdad, an incident that exposed the accountability gap at the heart of the PMC model.
The Nisour Square massacre raised fundamental questions. Blackwater personnel operated in a legal gray zone: they were not subject to Iraqi law under Coalition Provisional Authority Order 17, and their status under US military law was unclear. It took years of legal proceedings before four Blackwater guards were convicted in US civilian courts. The case illustrated how PMCs can operate in gaps between legal jurisdictions, making accountability for human rights violations extraordinarily difficult.
Regulating PMCs has proven enormously difficult. The 2008 Montreux Document, negotiated by Switzerland and the International Committee of the Red Cross, established voluntary good practices for states that hire or host PMCs. The International Code of Conduct for Private Security Providers followed in 2010. But these are voluntary frameworks, not binding law.
The fundamental problem is that PMCs allow governments to wage war with reduced political costs. Private contractors who die do not appear in official military casualty counts. PMC operations can be classified or denied. And the corporate structure creates distance between the state and the violence conducted on its behalf. For authoritarian regimes like Russia, PMCs provide plausible deniability for foreign military interventions. For democracies, they reduce the political pressure that comes with deploying uniformed troops.
On 16 September 2007, Blackwater contractors guarding a US State Department convoy opened fire in Baghdad's Nisour Square, killing 17 Iraqi civilians and wounding around 20. The case became the defining test of PMC accountability. Trace the jurisdictional gap step by step:
| Legal authority | Why it did not cleanly apply |
|---|---|
| Iraqi criminal law | Coalition Provisional Authority Order 17 (2004) granted contractors immunity from Iraqi prosecution |
| US military justice (UCMJ) | The guards were civilians, not uniformed service members |
| US civilian courts | Prosecutors had to stretch the Military Extraterritorial Jurisdiction Act (MEJA), written for DoD contractors, to a State Department contract |
The result: a first prosecution was dismissed in 2009 on Fifth Amendment grounds, revived on appeal, and only in 2014 did a US federal jury convict four guards (one of murder, three of manslaughter). In December 2020 President Trump pardoned all four. The nine-year path from massacre to conviction to pardon shows exactly why critics call PMCs an 'accountability gap': force projected abroad, but no single legal system reliably owning the consequences.
