Guerrilla warfare tactics are used for sabotage, ambushes, and attacks on persons and property or against isolated enemy posts. Guerrilla warfare tactics are characterized by mobility, surprise, and prompt disengagement. These tactics take advantage of knowledge of the natural environment and the sympathy (or passive attitude) of the local population. Guerrilla warfare is waged by small widely scattered formations fighting superior forces whose flanks and rear they attack at unexpected places and times. See Armed forces, Combatants, Conflicts not of an international characterAsymmetric warfare; Fighters;
