In an armoured vehicle with a turret, a weapon mounted therein and a magazine housed in the armoured vehicle and receiving large calibre ammunition in the upright position in a concentric arrangement with respect to the turret rotation axis is arranged a loader, which has a loading arm gripping the ammunition on the magazine and raising it into an aligned position with the weapon bore axis, i.e. the loading position. The loader is arranged on a ring mount positioned roughly below the weapon breech block on the turret platform and whose rotation axis coincides with that of the turret and has a multilever guide supported on the ring mount and movable in a vertical plane, which raises the loading arm with the upright ammunition in a steep movement path and only towards the end of the movement path swings into the loading position.
