Knight Banners included in a Dominus Battleforce maniple cannot benefit from obscuring cover (see the Adeptus Titanicus rulebook). If a Knight Banner from a Dominus Battleforce maniple is wholly within 6" of a Titan from the same maniple (i.e., all Knights from the Banner are within 6" of the Titan), and both the Titan and at least one Knight from that Banner is visible to the attacker, attacks made against the Titan from more than 2" away from the Titan suffer a -1 modifier to the Hit roll.
