A musketeer (French: mousquetaire) was an early modern type of infantry soldier equipped with a musket. Musketeers were an important part of early modern armies, particularly in Europe. They sometimes could fight on horseback, like a dragoon or a cavalryman. The musketeer was a precursor to the rifleman. Muskets were replaced by rifles in most western armies during the mid-1850s. The traditional designation of "musketeer" for an infantry private survived in the Imperial German Army until World War I.
