"Let the Angels of Death assist us" - Using Space Marines in your Inquisition armies

The Inquisition may take either Initiate Space Marines or Imperial Guard in an army. This works in the following ways:
0-1 HQ choice - This may not be a Chapter Master or a named Special Character. Librarians may not be used in an Ordo Malleus or Ordo Heredicus army, so don't try this combination. Pedro Kantor/Kato Sicarius may be used in Campaigns including Orks, Marneus Calgar when battling Tyranids, Korsarro Khan when battling Dark Eldar, and Kayvaan Shrike when batting a Cities of Death battle
0-1 Elite choice (0-2 if your Pedro Kantor is in your army) - This may be anything, except from 2 squads of Terminators if within a Campaign. If Pedro Kantor is in the army, one of these must be a squad of Sternguard. If Kato Sicarius is in your army, one of these must be a Dreadnought
0-3 Troop choices - Only 1 of these choices may use the 'Knower of Secrets' special rules. Telion and variants may NOT be used in Scout Squads
0-1 Fast Attack choice (0-2 if Shrike or Korsarro Khan is in the army) - If Shrike is in the army, one of these must be armed with Jump Packs, and if Korsarro is in the army one of these must be armed with Bikes
0-1 Heavy Support (0-2 if Marneus Calgar is in the army) - You may not have Chronus commanding a vehicle. All Heavy Support counts towards Righteous Zeal

In addition, all Space Marine units except where noted gain the 'Knower of Secrets' special rule. Only the above choices gain this rule - what Inquisitor would have entire ARMIES of Marines knowing the unholy truths?
Knower of Secrets: If the entire Space Marine army is defeated, the opposing player counts as holding an additional objective/scoring +2 kill points. The units with this special rule gain 'Acute Senses' and 'Burn the (appropriate arm of the inquisition's enemies) special rules. When the game ends, instead of packing up the opposing player gains control of the Inquisition parts of the army - this part of the army will then attempt the kill off as many Space Marines as possible. These destroyed marines count towards the final game score (if a Marine squad holding an objective is destroyed, causing a 2-2 score instead of 3-2 to the Inquisition, then the game is a draw etc), but the first part of this rule is ignored (the opposing player does not gain +2 kill points/additional objective for destroying the entire Space Marine force)
