The word dragoon originally meant mounted infantry, who were trained in horse riding as well as infantry fighting skills. However, usage altered over time and during the 18th century, dragoons evolved into conventional light cavalry units and personnel. The name is possibly derived from a type of firearm (called a dragon) carried by dragoons of the French Army. There is no distinction between the words dragon and dragoon in French; both are referred to as dragon.
