Abstract: A medium-caliber ammunition supply device for a turret mounted on an armored vehicle includes: at least one circular turntable, placed at the rear of the turret, for positioning medium-caliber ammunition in a strip or chain, vertically and along a spiral path; and structural elements for guided and pulled conveyance of at least one strip or chain of medium-caliber ammunition. The structural elements include at least a conveyor and a ratchet box. The structural elements successively include a first conveyor, a first ratchet box, a second conveyor, and a second ratchet box. The at least one circular turntable and the structural elements all are covered with a sheet-metal protection on their side faces and/or on an upper part or roof. The sheet metal protection has mobile hatches mounted in a rotating or pivoting manner, allowing partial or complete and ergonomic (re)loading and/or unloading of the at least one circular turntable.

Abstract: A system for attaching and/or detaching ammunition having the form of a linked chain or strip includes a chain of ammunition having a head, a case, and a base that are essentially cylindrical, successively attached to one another by links, each link including a first part and a second part, articulated and offset relative to one another, the second part including a loop or ansa that is central relative to a height of the link, defining an approximately semi-cylindrical opening, dimensioned to be adjusted on the case of a cartridge of a given caliber, the first part including two loops of this type but situated, in terms of height, respectively on either side of the central loop, at least the central loop including, at its free ends, a small loop oriented in a direction opposite that of a main loop, so as to define a flare.
