Abstract: The invention relates to an episcopic sight usable for observation and firing by day or night on a vehicle equipped with a gun. The sight includes an assembly of interchangeable moduli grouping the optical elements, particularly made of a head modulus 1 containing a mirror controlled in elevation, a height increase modulus 2, a day sight modulus 4, a night sight modulus 5, a rangefinder modulus 6, an electronic case associated to a fire-control computer. It includes a modulus of separation 3 of the day and night channels interposed between the height increase modulus 2, and the day and night moduli 4, 5, the modulus of separation 3 containing the means for generating a sight reticle in the day and night channels. The means of generating a firing reticle include a projection collimator of this reticle and a rhombohedron to inject this reticle into the day and night moduli.

Abstract: This invention concerns a fire control system which is adaptable on a mantlet sight of a combat vehicle, and, in particular, is of the type that comprises a stabilized mirror 10, a rangefinder laser 13 and an electronic control unit.The fire control system of the present invention includes a casing welded onto the turret mantlet, which contains a stabilized mirror inclined with respect to the horizontal line so as to correlate the stabilized aiming axis through the mirror to the gun trunnion axis and the firing axis, a laser being arranged so as to send and receive beams along the sight aiming axis of the mantlet sight and of the stabilized sight. Optical means are located between the stabilized mirror and the sight and are made up of a semi-transparent plate, a dichroic plate and a mirror to ensure the harmonization of the laser transmission and reception beams with respect to the aiming axis of the sight.The dichroic plate is fixed and inclined at 45.degree.
