Mercenary forces are private military groups that offer their services for financial compensation rather than loyalty to a nation or ideology. These groups can be hired by governments, corporations, or individuals to perform various tasks, including combat, security, and training. Their use has become more common in modern conflicts, where traditional military forces may be limited. The legality and ethics of employing mercenaries are often debated. Some countries have laws regulating their use, while others may not recognize them as legitimate combatants under international law. Notable examples of mercenary forces include Blackwater and Wagner Group, which have gained attention for their roles in various conflicts.
