Guerrilla warfare is a military strategy characterized by small, mobile groups of irregular fighters using ambush tactics, sabotage, and hit-and-run operations against larger, conventional forces. This form of warfare often relies on the element of surprise and a deep understanding of the local terrain, making it an effective response to more powerful enemies, particularly in contexts where traditional military engagements are impractical. Guerrilla warfare has been employed as a key strategy by Native Americans in their resistance to colonization and their adaptation efforts in the face of external threats.
