Light infantry refers to a type of military unit that is trained to move quickly and operate in various terrains. Unlike heavy infantry, light infantry soldiers carry less equipment, allowing them to be more agile and flexible in combat. They often engage in skirmishes, reconnaissance, and rapid assaults, making them essential for modern warfare. These units typically use lighter weapons and rely on speed and stealth rather than heavy armor. Light infantry can be deployed in diverse environments, including urban areas and forests, and are often used in conjunction with other forces, such as mechanized infantry or special operations forces.
