Well.....It wasn't actually done quickly. I've been plunking away at these guys for a few weeks now. I really can't seem to focus work on anything for very long, so I often have endless half finished projects on the go. These guys were in the roster for the Caffeineforge weekly paint up (on hiatus at the moment).
A trial model, the sergeant, was done a few weeks ago, so it was pretty easy to replicate, and bang out, the remaining guys. I botched the bright green a few times until I rediscovered what I'd used. And, typically for bones, the faces of the helmetless mooks are pretty poor castings. These guys were finished much quicker than normal for me (actual elapsed working time), so I'm pretty happy with their passable tabletop standard. Also that's 9 more Bones done, which is a nice bump to my low numbers this year so far.
