Light cavalry refers to a type of military unit that is typically faster and more mobile than heavy cavalry. These troops are often used for reconnaissance, skirmishing, and flanking maneuvers. They are usually equipped with lighter armor and weapons, allowing them to move quickly across the battlefield and engage in hit-and-run tactics. Historically, light cavalry has played a significant role in various conflicts, including those involving Napoleon Bonaparte and the American Civil War. Units like the Hussars and Lancers are examples of light cavalry that were known for their speed and agility, making them effective in both offensive and defensive operations.
