The Prussian reforms of 1808 absorbed the Fusiliers as the third battalion of each line infantry regiment. Now wearing blue uniforms, they were distinguished by black leather belts, and a slightly different arrangement of cartridge pouch.
In the Prussian Army of 1870, Infantry Regiments 33 to 40 plus Regiments 73 (Hanover), 80 (Hesse-Kassel) 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.
