Private military companies have a controversial but important role to play in global security. These contractors are independent businesses that offer specialized military services related to war, combat operations, intelligence gathering and more, to national governments, substate actors, and international organizations.

A majority of these private companies are led by military veterans and offer several war-related services, consultancies, and other forms of support such as construction, logistics, and training. For example, Academi, formerly Blackwater, was founded by Erik Prince, a former Navy Seal. Many of them are even equipped with fleets of utility and transport aircraft.

After World War II, many western countries privatized arms manufacturing, and this was followed by military services. The use of private military companies further gained prominence with the conclusion of the Cold War in 1990, with the United States, United Kingdom, and Russia downsizing their militaries, which resulted in a large number of soldiers left unemployed. This vacuum was filled by private military companies, who were often contracted by the same countries to do their 'dirty work' without directly involving themselves militarily in conflicts.

According to DW News, the United States spent around $300 billion between 1994 and 2007 on 12 private militias, mainly in Afghanistan and Iraq. On the other hand, the Wagner Group has for the last several years been actively advancing Russian security interests in Syria first, and later Ukraine. Not only do private contractors offer the benefit to countries of not involving themselves directly in the conflict, but also that any casualties faced by these private companies do not evoke the same emotional response and pressures at home as it would if soldiers of a national army were to die in an external war.

However, incidents over the last couple of decades have shown that it is not always beneficial for countries to cede their monopoly over power and coercion to private contractors. The most notable learning of this was the 2023 mutiny by the Wagner Group in Russia, in which thousands of mercenary fighters that were engaged in the conflict in Ukraine rebelled against Putin’s government and decided to march towards Moscow. Moreover, there were also numerous instances of shootings carried out by private military contractors during the Iraq war on both American and Iraqi troops, as well as civilians.
