lancer
Lancer is a term used to describe a cavalryman equipped with a long spear or lance. The word derives from the practice of utilizing lances in mounted combat and became a standard designation in many European languages. Lancer regiments first emerged in the late medieval period and remained prominent in early modern armies, with notable examples including light cavalry formations such as the Polish uhlans. The effectiveness of lance-armed cavalry depended on speed, momentum, and precise thrusts, but the rise of firearms and changes in tactics gradually reduced the battlefield role of traditional lancers. By the 19th century, many lancer units were reorganized or converted, though some persisted in ceremonial roles or as historical designations within modern armed forces.
In modern popular culture, the term Lancer is widely used as an archetype for spear- or lance-wielding
The term Lancer can also appear in historical and military literature as a general designation for cavalry
