Mounted infantry refers to soldiers who are trained to fight on foot but use horses for mobility. This allows them to quickly move to different locations on the battlefield, providing a tactical advantage. They can engage in combat while dismounted, using their training in infantry tactics. Historically, mounted infantry played a significant role in various conflicts, especially before the widespread use of mechanized vehicles. Units like the U.S. Cavalry and British Yeomanry exemplified this approach, combining the speed of cavalry with the combat skills of infantry. This hybrid strategy allowed for greater flexibility in military operations.
