ABSTRACT:
A fire control device for sighting a gun by introducing, between the axis of the gun and the direction of the target, an angular shift based on the trajectory of the ammunition, the device comprises a sighting telescope in which an image of fire crosswires defining a line of collimation are visible and means for moving the fire crosswires in dependance on a signal from a rangefinder of the laser type which includes a first collimator comprising an objective and crosswires for sighting the rangefinder and an image of which can be seen in the telescope, and a second collimator for shifting the line of collimation which comprises an objective and the fire crosswires which are placed at the focal point of the objective, the second collimator being associated with an optical reflecting element for reflecting the image of the fire crosswires into the telescope and the two collimators are arranged so that the image of the sighting crosswires passes through the optical reflecting element and is reflected by the fire crosswires towards the optical reflecting element, the fire crosswires being provided with a reflecting face for this purpose.
