What is "francs-tireurs"

Francs-tireurs (, French for "free shooters") was a term for irregular military applied to 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 the Germans during World War II.

It is sometimes used to refer more generally to guerrilla fighters who operate outside the laws of war.
