Abstract: An armoured vehicle turret that can accommodate a crew including a gunner includes: a fixed roof with an opening; a retractable protection system having an armoured cover or dome, that is pivotably movable about a horizontal axis and/or in vertical translation, the retractable protection system being capable of assuming: a first position in which the retractable protection system is retracted against the roof and ensures a closing of the opening; a second partial open position in which the retractable protection system is partially deployed in vertical translation upwards so as to protect a soldier in an observation position; a third partial open position in which the retractable protection system is partially deployed in vertical translation upwards more so than in the second position, so as to protect the soldier in a sniper position; and a fourth fully open position in which the retractable protection system is fully deployed.
