The Corkscrew Tank was developed by the Russians and was mostly used during the Cold War. The corkscrew design made it ideal for use in the extreme winters, as it didn’t get bogged down in snow and ice like other vehicles. It was even able to travel sideways, which helped when it got stuck.
Strangely enough, the Corkscrew Tank was unable to efficiently travel over normal terrain. It was extremely effective for navigating the frozen tundra, but couldn’t do much outside of that. The vehicle also had difficult being steered as the screws couldn’t be aimed from side to side. There was no suspension on the tank which also complicated things.
However, the tank was pretty cool looking and was able to do things that other tanks couldn’t.
