Editing Warhammer 40,000/7th Edition Tactics/Officio Assassinorum (section)

==Battle Brothers==

*'''Adepta Sororitas:''' Sisters are arguably the ones that benefit the most from Officio Assasinorium. All four assassins can bring something to the table for the nuns. Vindicares can hit vehicles where your Exorcist can't touch them and will help keep your Cannoness out of challenges by sniping dedicated CC characters. The Callidus can sneak behind enemy lines and provide ample distraction so your heavy flamers can get close. Speaking of flamers, an Evesor alongside an army with Sisters with a shitton of flamers will be the absolute bane of any horde army like Orks or Renegades. Culexus assassins can mix very well with Sisters since they have Shield of Faith (Adamantium Will/6++), making an anti-psyker force unlike any other.
*'''Astra Militarum:''' Assasinorium is an all around good choice for Guard. Vindicares and Eversors can distract and whittle down squads to a more manageable size for your lasguns to handle. Callidus and Culexus can still be a huge distraction and the bane of psykers, respectively. Fairly straightforward and simple, frankly. Can't hurt to have an assassin in your army but you won't be damned if you don't bring one.
*'''Imperial Knights:''' Assassins can't do much for Imperial Knights besides provide a little extra firepower that they might not need. Callidus can [[rape|touch them]] where Knights might not reach, while Culexus can tailor specifically to psykers. Vindicares may be a bit redundant since Knights have anti-armor in spades, as well as Eversors since they don't lack blast weapons either. Certainly can't hurt to take one though if you have the points for it.
*'''Skitarii/Cult Mechanicus:''' All of the assassins can help an AdMech list. Need some infiltration and mind-fuckery? They got Callidus Assassins. Need some more [[Rip and tear|Rip'N'Tear]]? They got Eversor Assassins. Need some long-ranged firepower to take out vehicles and characters? They got Vindicare Assassins. Need to ruin a psyker's day? They got Culexus Assassin. Culexus will probably be your best choice though since the Mechanicus don't have the best options to counter psychic powers. However, for the Skitarii specifically, you may want to consider if you need an assasin to perform the role in question. Sicarian Infiltrators and Ruststalkers can do pretty puch the same job as a Callidus or Eversor and a squad of five Rangers with two transuranic arquebuses and an omnispex can perform the role of a Vindicare.
*'''Space Marines:''' To be honest, there's not much the assassins can add that TEH EMPRA'S FUREH already have. Vindicares an pick off characters but anti-armor is not a problem for the Astartes. Callidus are nice but we already have scouts and drop pods. Eversors can chew through swarms, yes, but Assault Terminators with Lightning Claws and that bullshit Vindicator formation can do the job just as easily. Culexus, however, can make that Chaos Sorcerer or Farseer his bitch and bring something new to the table. ''However''; if you ever try to bring a Culexus alongside Grey Knights, consider yourself a winner of the Darwin Award.
