Hey, after reading parhaius' codex in the imperial guard army - i made the following army (2000 pts)
It is disigned as a Arbites Quick Response and Execution Force, changing the veterans doctrine to sharpshooters. in this case all troops can deep strike if allowed, even if not stated on list. I have placed all heavy weapons in HQ for ease so that the rest can easily assault and suppress the rebels.
My thanks goes to Parhaius as A) i like the idea and I now have good ideas for my arbites in Necromunda
Please comment on the list
