In summary, the Reffye mitrailleuse was rarely used to deliver sweeping fire at close range like modern machine guns. The mitrailleuse six-gun batteries had been designed to deliver fire on targets too distant to be reached with Chassepot infantry rifles or artillery grapeshot. To fulfill this role, at least during the early weeks of the campaign, the mitrailleuses were deployed together with the older "Napoleon" muzzle loaded field guns ("canon obusier de 12") used by the French Army during the Franco-Prussian War. The mitrailleuse crews are on record of having generally objected to being placed in proximity to regular artillery batteries .
