As you might expect, tank drivers need plenty of training. The M1A1 Abrams might only be able to travel 70km/h on tarmac and 50km/h off road, but it weighs over 60 tonnes, so if you make a mistake it's going to be quite a clean-up job.
This video shows U.S. Marines undergoing training in Norway to improve their capabilities of operating in cold-weather environments, which appears to involve driving very sideways as often as possible.
