Belt-fed

In the context of machine guns, a means of supplying a continuous stream of ammunition, linked together in a flexible belt. "Belt" usually implies that there will be some manual handling of the ammunition; magazine-fed machine guns may internally have a structure similar to a belt, but the magazines are changed as a unit without manipulating the belt.

The belt may be constructed with disintegrating links, which fall off as the cartriges enter the gun, or the gun's mechanism may extract bullets from a reusable belt, the reusable belt coiling underneath the gun.

Examples of belt-fed machine guns include the M240, M249, M60 and M2. They contrast with magazine-fed units such as the M149.
