Throughout the history of warfare, armies have looked for ways to attack the enemy while defending themselves from harm, which led to some pretty strange battle machines. These defensive conveyances evolved into the modern tank, with many odd permutations along the way. Some designs were inspired by nature, such as the armor worn by turtles or beetles, as you can see in the 1855 British steam engine design shown here. See a lot more at Dark Roasted Blend. Link
