Dragoons were a type of mounted infantry that originated in the 17th century. They were trained to fight both on horseback and on foot, allowing them to adapt to various combat situations. The name "dragoon" is believed to come from the dragon, a type of firearm that soldiers carried. Initially, dragoons served as light cavalry, performing reconnaissance and skirmishing duties. Over time, their role evolved, and they became more integrated into traditional cavalry units. Dragoons played significant roles in many historical conflicts, including the Napoleonic Wars and the American Civil War.
