Abstract
Abstract A combat vehicle, especially an armored vehicle, with a rotating turret on a hull and with an entry-and-exit hatch that can be closed with a cover and that is mounted in the roof of the hull. The parts of the roof of the hull in the vicinity of the hatch consist of a circular plate that rotates on an axis perpendicular to the roof and in which the hatch is positioned in the plate eccentric to its axis of rotation. To make the hatch as small as possible, while permitting exit from the vehicle at all turret positions, the position of the hatch can be varied.
