Blueprint: Mark XO

==Description==
When people in the Valley say that things used to be built to last for centuries, they usually refer to the legendary tank "Mark". After standing in a museum for more than a century, this machine still ended up in action, but this time after the catastrophe. For many years the vehicle served lieutenant Mitchell, assisting him in the difficult mission of rescuing people. During that time "Mark" underwent many repairs, but each one made the tank even better, adapting it more and more to the harsh "climate" of the Wasteland.
