Dark Heresy Mass Combat Rules

I have written up some rules for handling huge battles in Dark Heresy, the 40K roleplaying game from Fantasy Flight Games. I have based it largely upon another of my more favorite roleplaying games - Pendragon. In Pendragon, one of the best portions of the game was the way in which large battles were handled by focusing on actions and encounters that the players had within a battle. This is the type of rules I tried to create for Dark Heresy. Have a look and let me know what you think, or if you spot any problems!
