Abstract
A combat vehicle, especially a military tank, has a hatchway in its armored roof and periscopes in the immediate vicinity of the hatchway. Each periscope has an ocular inside the vehicle and an objective outside it. A channel that accommodates the optical path extends between them. The channel extends through a protective block of neutral material on the roof of the vehicle. At least one section of the channel is completely occupied by optical glass. The ocular extends directly out of that section although the objective rests on the top of the block. The block can consist of a stack of separate sheets. The objective can have an outlook aperture and a direct-view aperture. The mirror in the objective can be semitransparent or moved out of the optical path.
