Private Military Contractors (PMCs) are private companies that provide military services, including security, logistics, and training. They often operate in conflict zones and can be hired by governments, corporations, or non-governmental organizations to perform tasks that may include protecting personnel or facilities. PMCs have gained prominence since the late 20th century, especially during conflicts like the Iraq War. They can offer specialized skills and flexibility that traditional military forces may not provide. However, their use raises questions about accountability and the legal implications of employing private forces in warfare.
