A guerrilla fighter is an INSURGENT, or a person who actively resists authority, usually through unconventional warfare. Guerrilla fighters are typically members of a small, organized group that uses tactics such as ambushes, sabotage, raids, and hit-and-run attacks to disrupt the enemy's operations. They often operate in hostile environments and use guerrilla tactics to gain an advantage over their opponents. Guerrilla fighters are often seen as a symbol of resistance against oppressive regimes and are often associated with revolutionary movements.
