Thanks all. Next time, I'll take pix in the daylight.
The Ratnik figs are excellent, very cool details, and it forced me to try a different painting technique. I'm going to do all of them that way. The wire: yep, it's a barbed wire remnant in the foreground. Bad angle on the picture.
The earlier figs are either RAFM or Assault Group with (mostly) Pig Iron head swaps. They lack the distinct individual character of the LAM/Ratnik figs, but they're solid, clean sculpts. They fill out the collection nicely.
