As a halftrack I can see a lot of uses with the Dreamforge Eisenkern stormtroopers etc.
PS: The nice thing is that you could super easily argue that it's simply a BTR-40 that's been modified after damage or modified to support an artillery piece or heavy mortar. Some re-welding and adding wheels would be cake for a small shop. I think it'd look perfect with a heavy mortar mounted in the back, or a small anti-aircraft radar etc.
