Tortoise: Slow Menace

World War I left a lasting mark on military doctrine. Breaking through trenches and networks of fortified positions proved to be a very important but incredibly difficult challenge, and for a long time, no one could find the perfect solution. There was artillery, there was air power, there were other long-range strike options, but what the reality of the battlefield really demanded was a protected, reasonably mobile vehicle that could punch through enemy lines. Over time, that need gave rise to the idea of the super-heavy tank, a kind of “mobile fortress”. One such vehicle was the Tortoise, a true moving bunker wrapped in thick armor and armed to the teeth.
