Get over to Mad Robot Miniatures and get reinforced!
I love Commissars. The brutality they add to the grimdark of 40k is unmistakable. I used to have a fair selection of Commissars, and I'm working it back up again. I've recently added the power sword power fist Commissar and the power axe Commissar to my collection and I think that brings me up to eight if I am counting right,.. I expect Steve's new kit to add a couple more to my ranks soon enough.
Cheers!
