A tank with an overlying gun which is mounted in a cradle disposed on the crew turret also includes a loading pendulum which is disposed on a journal ring and pivotal in relation to the crew turret. The loading pendulum and the gun are asymmetrically journalled, such that the positions of the gun and the loading pendulum are dependent upon the elevation/depression of the gun. The gun is longitudinally/vertically displaced in the plane of elevation on elevation/depression. This is achieved in that the cradle is retractably disposed in the plane of elevation with the aid of a member determining the degree of retraction of the gun and may be elevated/depressed about an abutment pivotally mounted between the revolving portion, or turret, and the gun. The abutment is movable in the plane of elevation. The abutment and the cradle are adapted in the different elevations/depressions, to adjust the position of the breech of the gun to the pivotal movement of the loading pendulum about its pivotal center.
