These are from the plastic sprue released with Advanced Space Crusade. Admittedly they hail from the era of gurning, lumpen plastic miniatures, but I love them all the same. While they don't have the dynamism of their metal counterparts, they do have a kind of solid charm. Plus you really can't miss that MASSIVE gun and bright yellow chainsword, which helps with my 10th Company's identity crisis.
What I love about this cra-zy era is the liberal incorporation of heraldry. I took the the Dave Gallagher White Dwarf cover and 'Eavy Metal miniature below as reference points.
