What is a person who wages an unofficial war on a country?

Answer 1

A person who wages an unofficial war on a country is often referred to as a "guerrilla fighter" or "insurgent." These individuals typically engage in irregular warfare, employing tactics such as ambushes, sabotage, and hit-and-run attacks against a more conventional military force. They may operate independently or as part of a larger movement, often motivated by political, ideological, or social objectives. Their actions are usually considered outside the bounds of formal military engagement and can complicate traditional conflict dynamics.
