Francs-tireurs (pronounced [fʁɑ̃.ti.ʁœʁ], French for "free shooters") were irregular military formations deployed by France during the early stages of the Franco-Prussian War (1870–71). The term was revived and used by partisans to name two major French Resistance movements set up to fight against Nazi Germany during World War II.[1]
The term is sometimes used to refer more generally to guerrilla fighters who operate outside the laws of war.[2][3]
