...well, by Command Squad what I really mean is just the standard bearer and the apothecary. Seeing as the death guard are mostly white I thought I'd go with the total opposite for the apothecary. The head is just one of the Chaos Space marine heads but it seemed to suit the model quite well.
The banner was a bit tricky but with the help of a Crimson Fist icon I had the round space which would become the main symbol. The Garro model is just one of the Masters of the Chapter models with the power fist hand swapped for a bolter, as per the background fluff on Garro. I've included a picture of the back of the model as I'm still proud of the cloak and it seems a shame that its normally not really seen.
