Belted ammunition is a type of ammunition used primarily in machine guns. It uses a metal belt to hold the bullets together. However, there are synonyms that can be used to refer to the same type of ammunition. Some of these synonyms include linked ammunition, chain ammunition, and box-fed ammunition. The term "linked ammunition" is used when the bullets are connected to each other through a metal link. The term "chain ammunition" is similar but not as common. Finally, "box-fed ammunition" refers to a type of belted ammunition where the bullets are fed into the gun from a box magazine. While these terms may not be as popular as "belted ammunition," they can serve as effective alternatives.
