A belt loaded with ammunition that is worn around the torso. Typically, each cartridge is held in its own loop along the length of the belt. They are often seen on gunslingers in old western-themed settings and characters, though modern bandoliers exist and are usually used to hold shotgun shells.
Not to be confused with an ammunition belt, which is a system to continuously feed automatic weapons such as machine guns and gatling guns. (Although technically, an ammunition belt can be worn.)
It is also not to be confused with a Sam Browne belt, a similar over the shoulder belt once used as a more effective replacement for the traditional "frog" waist belt clip for equipping a sword's scabbard, and primarily an aesthetic feature where it is in use now.
