Abstract: The turret (1) in accordance with the invention has two rotation axes, a vertical axis (A) and a horizontal axis (B); it includes a weapon (2), aiming means (3) and two motors, one part (10) of the turret (1) being turned about the vertical axis (A) by the first motor and the weapon (2) and the aiming means (3) being turned about the horizontal axis (B) by the second motor; it is characterized in that an additional element (6) is turned to coaxially about the vertical axis (B) by a third motor that is specific to it. The turret (1) is thus equipped with two motors rated to turn on the one hand the mobile part (10) of the turret about the vertical axis (A) and on the other hand the weapon (2) and the aiming means (3) about the horizontal axis (B). The turret (1) is thus rated optimally; the additional element (6) has a dedicated motor that is also rated optimally and can be of different powers depending on the inherent characteristics of this element (weight, inertia, etc).

Abstract: An element fixing device comprises a rail (1,1?,1?) with an upper wall (I1) and lateral walls (12,13). The upper wall has openings (2) with a first part which permits the passage of a screw head (5) for the fixing element and a second narrower section (22) which permits the sliding passage of a shaft (4) of a fixing screw, the edges of which serve to grip the screw head on the tightening thereof, the head of the screw being housed between the lateral walls of the rail.
