As a quick note, the station is riddled with air vents, access ducts, and maintenance conduits that can be used to bypass areas of the station or launch surprise assaults.  All known ducts to the officer's quarters have been cut, and none exist to the munitiorium, vault, or its security corridor, but otherwise three dimensional maneuvering is possible.<br/><br/>I also posted squad combat rules in the rules and mechanics OOC thread under combat rules.  They're basically the squadron rules from Battlefleet Koronus for characters, and they're mostly there to speed up combat.  (and also make being outnumbered easier to survive)
