A machine gun unit comprises a machine gun mounted to a support by a mounting permitting pivoting movement of the machine gun relative to the support in azimuth and/or elevation. Angle encoders provide position signals representing angular displacement of the machine gun relative to the support. An aiming system comprises a sensor, for example a CCD sensor, which provides a video signal representing a field of view for the aiming system, a display device for displaying the field of view, a manual input interface, a graphics artifact generator, and a digital signal processor (DSP). The DSP monitors the outputs of the angle encoders and controls the graphics artifact generator to combine the output of the graphics artifact generator with the output of the CCD sensor for display by the display device. Various graphics artifacts can be provided. Masks may be provided for delimiting field of fire. A cursor may be repositioned to reflect superelevation requirements. Target motion and opposing fire can be detected and highlighted. Tracers can be simulated. The weapon can also be used for surveillance, either alone or as part of a weapon system comprising a plurality of the weapons and a central command post.
