Did up some self propelling Artillery "units" for the Venus Campaign. Thought to take a slightly different approach, pressing local "resources" into service, with the knowledge that mind controlling devices would be employed.
So, I first had to scratch build 2 Gatling guns and 2 light artillery pieces to mount on my "self propelling units".

I successfully raided the styrene and bits box for items to assemble the assorted guns with. The mind control units are from space Marine jet packs. Not happy yet with the over all color scheme of the bugs and am open to suggestions. Otherwise, not to bad for mind controlled, self propelled artillery "units".
