The cases were issued in pairs and worn at the front of the belt on either side of the buckle. Like all other M-1956 equipment they were constructed of heavy canvas. The top flap was closed by means of a metal eyelet and cloth tab closure. Early models featured a steel plate at the front both to maintain rigidity and to protect the ammunition. Two hand grenades of any type in the US arsenal could be attached on either side of each pouch, with the spoon hooked through a web strap and another web strap with snap-closure wrapped around the top. Like other pouches in the system, the ammunition pouches each attached to the web belt with a pair of slide keepers and, uniquely, an adjustable length strap with a closable hook which connected to the rectangular hook on the suspenders, intended to keep the case upright and transfer some of the weight directly to the shoulders.
