This is the start of my grand project to make a kill team for every faction. I have every 6th ed. codex so far and I intend to collect them all. So I want to use them for something, but as I can't make a full sized army for every faction this is the next best thing!
The one I chose to start with is a space marine scout kill team. The list can be found
here. It's going to be either white scars or white scar successor (marauders maybe?)
I brought a set of respirator Elysian heads to use, because frankly the scout heads are silly. Plus, I'm in the 'helmets are needed in the far future' camp.
I actually saw this before in WD with a crimson fist army. It's what inspired the idea. The other options available were cadian heads or even power armour marine heads. But I think I made the right choice. I'll post pics of them as I make them.
EDIT:
Here is what I have created so far. They are not the best quality pictures I know. But don't those heads work well with everything?
