Modern light machine guns often fire smaller-caliber cartridges than medium machine guns, and are usually lighter and more compact. However a light machine gun is defined by its usage as well as its specifications: some machine guns - notably general-purpose machine guns - may be deployed either as a light machine gun or a medium machine gun. Deployed with a bipod, and firing short bursts it is a light machine gun; if deployed on a tripod and used for sustained-fire it is a medium machine gun.
It is possible to fire a light machine gun from the hip or on the move as a form of suppressive fire intended to pin down the enemy. Marching fire is a specific tactic which relies on this capability. Otherwise, light machine guns are usually fired from a prone position using a bipod.
Many light machine guns (such as the Bren gun or the M1918 Browning Automatic Rifle) were magazine-fed. Others, such as the MG 34, could be fed either from a belt or a magazine. Modern light machine guns are designed to fire more rounds of a smaller caliber and as such tend to be belt-fed. Some LMGs, such as the Russian RPK, are modifications of existing assault rifle designs. Adaptations generally include a larger magazine, a heavier barrel to resist overheating, a more robust mechanism to support sustained fire and a bipod. Other modern light machine guns, such as the FN Minimi, are capable of firing from either an ammunition belt or a detachable box magazine. Lighter modern LMGs have enabled them to be issued down at the fireteam level and at two or three at the section/squad.
