it was back to the sketch book while the computer was offline. the basic concept comes from the hood of a tractor, that big angled hood thing. i ended up slowly moving away from it as the designs progressed.
also, as you may have noticed they are all 'gunless,' i wanted more of a 'sensory' priority to these vehicles like a forward spotter, and less 'bang bang.' there's room for some 50 cal guns, but i didn't want the long shell canons getting in the way of the other shapes.
