Having postulated the existence of these gigantic tanks in the setting. I needed a model to represent them on the tabletop. So where do you find a really big tank, that won't break the budget? Well...you ask the community over at The Miniatures Page.
While I appreciate the references to using the 15mm P-1000 Ratte, its almost too big. But we found a winner!
I got a great reference to Hobby Link Japan's ridiculous sale ($4.61 each!) of 1/72 scale pre-assembled, painted and weathered MAUS. These slab sided behemoths are perfect for the look I am striving to achieve.
Here a quick comparison of the kit right 'out of the box' next to some other vehicles.
