What is the doctrine of the DA? Am up in the air as to what chapter to paint my Primus marines. Have always liked DA. However, the doctrine of the Ultra Marines, (Being able to shoot in the same turn as they retreat from combat), and the Imperial Fists, (Ignoring the minus 1 to hit when targets are in cover), are very appealing.
If the DA doctrine matches these, I will go with them. If they don't, then UM it is. Will value your input greatly, mate... Be well!
