Iron Mountain Legion - Prototype Hover Tank - 13
The Iron Mountain Legion was an elite military group which remained sealed away in the Iron Mountain complex during the great war and its aftermath. They eventually emerged, taking the name of their base, as a new power in the post apocalyptic landscape. This tank was a prototype stored in the base before the war, and eventually repaired and brought into service in the aftermath.
I was inspired in building this by this piece of concept art.
