Insurgent forces are groups that rise up against an established authority, often a government, to challenge its control. These groups typically operate in a guerrilla warfare style, using unconventional tactics to achieve their goals. Insurgents may seek political, social, or economic change and often rely on local support to sustain their activities. These forces can vary widely in ideology and organization, ranging from nationalist movements to religious extremists. Insurgent groups may form in response to perceived oppression or injustice, and their actions can lead to prolonged conflicts, impacting the stability of the region. Examples of such groups include the Taliban in Afghanistan and the FARC in Colombia.
