Guerrilla groups are small, mobile, and flexible military units that use unconventional tactics to fight against larger, traditional forces. They often operate in rural or urban environments, employing hit-and-run strategies, ambushes, and sabotage to achieve their objectives. These groups typically rely on the support of local populations and may be motivated by political, social, or ideological goals. Historically, guerrilla warfare has been used in various conflicts around the world, including the Vietnam War and the Spanish Civil War. Notable guerrilla groups include the FARC in Colombia and the Maoist rebels in India. Their tactics can significantly impact the course of a conflict, often prolonging wars and complicating peace efforts.
