A Guerrilla Movement refers to a form of irregular warfare where small groups use tactics like ambushes, sabotage, and hit-and-run attacks against larger traditional military forces. These movements often arise in response to oppression or foreign occupation, aiming to disrupt and weaken the enemy while gaining support from the local population. Typically, guerrilla fighters operate in familiar terrain, such as forests or mountains, allowing them to evade capture. Historical examples include the Vietnamese during the Vietnam War and the Cuban Revolution led by Fidel Castro. Guerrilla movements can significantly impact political and military outcomes, often leading to prolonged conflicts.
