The patent application relates to a periscope for a military land vehicle to provide observation capability over hills or other obstacles. The periscope includes two telescopic tubes movable at different rates to position a sight head assembly at different elevated positions; a relatively large movement of the head assembly is achieved even though the vehicle has a relatively low silhouette. The sight head assembly includes two connected heads individually movable in the azimuth and elevational planes to provide complete scan of the terrain and airborne objects. The Commander of the vehicle can control the periscope while seated in one position, as necessary in a vehicle having very limited personnel space. (Author)
