Guerrilla warfare is a form of irregular warfare where small groups use tactics like ambushes, sabotage, and hit-and-run attacks against larger traditional military forces. This strategy relies on mobility, surprise, and the support of the local population to disrupt and weaken the enemy. Typically employed by weaker forces, guerrilla warfare aims to exhaust the opponent and create uncertainty. It has been used in various conflicts throughout history, including the Vietnam War and the American Revolutionary War, where smaller groups effectively challenged more powerful armies through unconventional tactics.
