An option for developing light tank projects with versatile armament including double-barreled autoloading guns. The vehicle was designed for a scope of tasks that was as broad as possible. It was both a fast, maneuverable scout and a support tank capable of flanking and firing from its rapid guns. An overhead weapon station with easy maintenance access and interchangeable cradles for mounting guns of different calibers made it possible to keep the vehicle's weight low while ensuring the required defense capabilities and a high degree of gun elevation/depression. By the time the blueprints were completed, the Vz. 71 was no longer required by the military. The scouting vehicle niche had already been filled by other machines, and vehicle armoring had notably improved. A light vehicle without missile armament thus became irrelevant.
