Light Machine Guns (LMGs) are a type of medium-to-heavy automatic firearm used by military personnel in various combat operations. They are typically belt-fed and are capable of firing large amounts of ammunition at once. LMGs are used by infantry troops to provide suppressive fire and to lay down covering fire for advancing troops. An LMG is typically heavier than other weapons, such as an assault rifle, and is usually carried by two people. Generally, the LMGs size and weight makes it difficult to use in close quarters combat. The ammunition used in an LMG is usually a 7.62mm NATO round or a 7.62x54mmR Russian round. This type of ammunition has greater penetrating power than an assault rifle and is more accurate at long distances. The rate of fire of an LMG can be adjusted to suit the situation, allowing for more control over the rate of fire provided by the weapon. It is important to note that LMGs are not suited for all combat situations, due to their weight and size they are not suitable for close quarters combat or urban combat scenarios.
