A Light Machine Gun (LMG) is a type of firearm designed to provide sustained fire support for infantry units. It is typically lighter than a standard machine gun, allowing soldiers to carry and operate it more easily in various combat situations. LMGs are often used to suppress enemy positions and provide cover for advancing troops. These weapons usually fire intermediate cartridges and can be fed from belts or magazines. Common examples of LMGs include the M249 and Bren gun. LMGs play a crucial role in modern warfare, enhancing the firepower and flexibility of ground forces.
