Partisan warfare refers to a form of irregular warfare where small groups of combatants, often called partisans, use unconventional tactics to fight against larger, traditional military forces. This type of warfare is typically employed by groups that lack the resources or manpower to engage in direct confrontation, relying instead on ambushes, sabotage, and hit-and-run tactics to disrupt enemy operations. Historically, partisan warfare has played a significant role in various conflicts, particularly during times of occupation or oppression. Notable examples include the French Resistance during World War II and the Vietnamese guerrilla tactics against American forces. These movements often draw support from the local population, making them difficult to eradicate.
