Teletanks were a series of experimental wireless remotely controlled unmanned tanks produced in the Soviet Union in the 1930s and early 1940s so as to reduce combat risk to soldiers.[1] A teletank is controlled by radio from a control tank at a distance of 500–1,500 metres (0.31–0.93 mi), the two constituting a telemechanical group.
While never in common use, the teletanks were used by the Soviet Red Army in the Winter War against Finland, with at least two teletank battalions at the beginning of the Eastern Front campaign in the Second World War.[1]
