Arquebusiers are the standard Gunpowder Infantry of the File:Gunpowder age small.jpg Gunpowder Age. They are the first standard unit of this class, replacing the now-obsolete Light Infantry. Arquebusiers are trained at the Barracks and are effective against all types of Infantry, but very weak against both Light and Heavy Cavalry. Arquebusiers complement the slower moving melee Elite Pikemen, which are much more effective against Cavalry, but lose to Infantry.
