Thank you for the additional ideas.
The Eldingar (HumHov) looks like what I am looking for Hellraiser. And they make a mini for it!
The Fusion Maultier looks okay, smaller and lighter armored then I was looking for. Thank you for the idea it Liam's Ghost!
It is leg infantry unfortunately Colt. I keep forgetting about the change in rules for the hovers, though a VTOL could still work, just really fragile. Guess I have to look at the hover rules again, though their main job is to get the grunts in position and then fade back and provide support.
I was looking at the Svantovit as a possibility. Not availalbe to Mercs, but spread out widely enough that some might end up in a TO&E.
