In the Prussian Army of 1870, Infantry Regiments 33 to 40 plus Regiments 73 (Hanover), 80 (Hesse-Kassel or Hesse-Cassel) and 86 (Schleswig-Holstein) were all designated as fusiliers, as was the Guard Fusilier Regiment. In addition, the third battalions of all guard, grenadier and line infantry regiments retained the designation 'Fusilier Battalion'. They were armed with a slightly shorter version of the Dreyse rifle ("Füsiliergewehr"), that took a sword bayonet ("Füsilier-Seitengewehr") rather than the standard socket bayonet. Although still theoretically skirmishers, in practice they differed little from their compatriots, as all Prussian infantry fought in a style that formed a dense 'firing' or 'skirmish' line.
