A grenade machine gun or other weapon which employs superelevation of the barrel comprises a barrel unit and an aiming system mounted upon a support. The aiming system is mounted to the weapon and the support by a coupling unit. The aiming system comprises an imaging and display unit for displaying an image of a scene including a target, angle encoders for providing a signal representing displacement of the imaging unit in elevation relative to the support, and a control unit, e.g. a computer, for selecting either of two states for the coupling unit. The first state entrains the imaging unit to move with the barrel. The second state secures the imaging unit to the support and allows the barrel to move relative to both, i.e. during superelevation of the barrel. The coupling unit may comprise a first part connected to the weapon for rotation in elevation with the barrel unit and a second part connected to the imaging unit. The control unit may comprise a computer for superimposing upon the image an aiming reticle and a rangefinder reticle, the former representing an aiming point of the imaging unit and the latter representing an aiming point of the rangefinder, and may adjust the position of the aiming reticle in dependence upon the elevation signal, and stores coordinates for selected positions. The control computer may offset the displacement signal to displace the aiming reticle relative to the field of view in a direction opposite to the required superelevation angle.

1. A weapon system comprising a weapon and an aiming system both mounted upon a support, the weapon having a barrel unit and the aiming system comprising:(i) an imaging unit for providing an image of a scene within a field of view of the imaging unit; (ii) a display unit for displaying the image; (iii) a coupling unit having a first part connected to the weapon for rotation in elevation with the barrel unit, a second part connected to the imaging unit and a third part connected to the support; the coupling unit having a first operational state in which the coupling unit fixes the imaging unit relative to the support while allowing elevation of the barrel unit relative thereto and a second, alternative state in which the coupling unit entrains the imaging unit to move with the barrel unit relative to the support, (iv) angle encoding means for providing a displacement signal representing displacement of the imaging unit in elevation relative to said first part; and (v) control means comprising means for controlling the coupling unit to select the first state and the second state alternatively and means responsive to the displacement signal for determining when a required change in elevation of the barrel unit relative to the support with the coupling unit in the first operational state has been effected and causing the display to provide an indication thereof.
