Answer:
Guerrilla warfare is a form of irregular warfare in which small groups of combatants utilize unorthodox tactics (i.e. sabotage, ambushes, raids, and "hit-and-run" tactics) against a larger military force.
Classic examples of guerrilla warfare include the attacks of more than 300 bands of French francs-tireurs, or snipers, on invading German troops during the Franco-Prussian War (1870-1871).
