What type of gun is the M249 classified as?

The M249 is classified as a machine gun due to its design and operational capabilities. Specifically, it is a light machine gun that is able to provide sustained automatic fire, which is a hallmark of machine guns. The M249 fires the 5.56x45mm NATO cartridge and is used primarily to provide infantry squads with a high volume of fire to support movement and suppress enemy positions.

Its functionality allows for both belt-fed ammunition and magazine-fed operations, contributing to its versatility in various combat scenarios. Unlike rifles or handguns, which are typically intended for more individual or precision shooting, the M249 is designed to lay down suppressive fire to cover troop movements and enhance firepower in a squad-level engagement.

This classification is essential, as it defines the M249's role on the battlefield compared to other types of firearms that have different intended uses and firing mechanisms.
