I spent yesterday building these guys, using parts from both my Forge World order and my bitz box. They're nothing too special, with the odd skull hanging on their belts and head swaps
I'm still looking for some bolters to give them, as I didn't order any from FW (a stupid oversight on my part). On the other hand, it gives me an opportunity to customise their weapons to make them stand out as veterans .
I should be finishing the squad some time tonight.
