After the Winter War, a report shows the Red Army came close to a breakthrough on the teletank.
Here s What You Need to Remember: Despite being at the cutting edge of technology, World War II–era drones were only effective in highly specialized circumstances, not ideal for the fast-paced ground warfare of the conflict.
