Editing Warhammer 40,000/9th Edition Tactics/Imperium (section)

===Agent of the Imperium Special Rule and Faction Keyword===
This is a recurring special rule in this Tactics Page. In a Battle-Forged Army, one {{W40kKeyword|Agent of the Imperium}} unit can be taken in each {{W40kKeyword|Imperium}} Patrol, Battalion, Brigade, Boarding Patrol, or Arks of Omen Detachment without those units taking up a Battlefield Role slot. The inclusion of those units does not prevent other units in their Army or Detachment gaining mono-faction abilities (e.g. Chapter Tactics and Combat Doctrines). {{W40kKeyword|Agent of the Imperium}} units included in one of the aforementioned Detachments are ignored for the purposes of Keywords when determining your Army Faction. {{W40kKeyword|Agent of the Imperium}} units cannot be included in a {{W40kKeyword|Fallen}} or {{W40kKeyword|Brood Brothers}} Detachment. 

Trying to build an {{W40kKeyword|AGENT OF THE IMPERIUM}} Detachment or Army is the most complex thing in the game. You ''can'' use {{W40kKeyword|AGENT OF THE IMPERIUM}} to build an Army as it is a Faction Keyword that is not {{W40kKeyword|IMPERIUM}}. The only compulsory unit is one Inquisitor, as your other {{W40kKeyword|AGENT OF THE IMPERIUM}} HQ (the Rogue Trader) cannot be a compulsory HQ choice as per their rules. There's also Ephrael Stern and Kyganil, but they're {{W40kKeyword|Sisters of Battle}} or Auxiliary Support Detachment only. 
* The only unit here without this Faction Keyword are Daemonhosts, so be warned any wannabe radicals. 
* {{W40kKeyword|Inquisition}} Patrol, Vanguard, or Arks of Omen Detachments are the only way to make a mono-faction {{W40kKeyword|Agent of the Imperium}} Detachment, but it's not worth losing out on all the other units just for Daemonhosts. 
* The Authority of the Inquisition rule limits Inquisitors to one-per{{W40kKeyword|Inquisition}} Detachment. However, if you build an {{W40kKeyword|Agent of the Imperium}} Detachment, this goes away. 
* If you want to be an absolute madman, you can take an Inquisitor and nine Assassins in an Arks of Omen Detachment.
* Don't forget, {{W40kKeyword|Imperial Knight Freeblades}} gain {{W40kKeyword|Agent of the Imperium}} when in a Super-Heavy Auxiliary Detachment. Canis Rex has {{W40kKeyword|Agent of the Imperium}} built-in, so you can take him normally in any {{W40kKeyword|Agent of the Imperium}} Detachment.
