Rebel forces are groups that oppose an established government or authority, often seeking to change political systems or gain independence. These groups can vary in size and organization, ranging from small militias to larger, more structured movements. They may use various tactics, including protests, armed conflict, or guerrilla warfare, to achieve their goals. Rebel forces can emerge in response to issues like oppression, corruption, or social injustice. Historical examples include the American Revolution against British rule and the French Resistance during World War II. The motivations and ideologies of rebel forces can differ significantly, influencing their strategies and outcomes.
