K-Wagen "Kolossal-Wagen" Super Heavy Breakthrough Tank

Another fairly ridiculous WWI tank that would loo perfectly in place in a post-apoc world, this one reminds me of the M577 Armored Personnel Carrier from Aliens. The K-Wagen lived up to it's name: 9 ft tall, 9 feet wide, and 15 feet long, and a crew of 22. It had 4 77mm guns and 7 machine guns and traveled at a blazing speed of 4.5 mph. Only two were produced. (The image below has the front on the right, rear on the left.)
