===Mechanicus Defense Cohort===

This army is quite the wall of steel and lasers. Without the Skitarii to provide the quick-firing weapons, you're going to be blasting things with prejudice. Your units will be tougher to shift.
<div class="mw-collapsible-content">

*'''Restrictions:''' Your army has to be from the same {{W40kKeyword|<Forge World>}} and cannot take any {{W40kKeyword|Skitarii}}.
**Bear in mind this cuts off access to all three of your transports.
*'''Benefits:'''
**All units gain the {{W40kKeyword|Mechanicus Defence Cohort}} keyword, enabling the Warlord Trait to work.
**'''Extremis Sentinel Protocols:''' All of your kataphrons, servitors, and kastelans gain the {{W40kKeyword|Extremis Sentinels}} keyword; they also lose access to forge world dogmas.
***Any model with this keyword reduces any damage taken by 1 (to a minimum of 1) whenever they're wholly within the DZ or wholly within range of an objective. Yeah, you'll need it because kataphrons are your only troops.
***Whenever any units with this keyword get charged, you can choose to either hold steady (allowing overwatch shots to hit on a 5+, but doesn't by itself let you overwatch) or set to defend (blocks overwatch, but they get a +1 to hit until the end of their next fight phase).  That's half of the Agripinaa dogma (the half you don't get is -1AP at half range with guns).
*'''Warlord Trait - ''Cacophonous Leadership'':''' While a friendly {{W40kKeyword|Mechanicus Defense Cohort}} unit is within 6" of the warlord, that unit has the Objective Secured ability. {{W40kKeyword|EXTREMIS SENTINEL}} models in such units count as one additional model when determining control of an objective marker.
**Kataphrons gain the ''least'' from this.
*'''Relic - Forgefire:''' Replaces a volkite blaster, making it only usable on the Dominus.  It upgrades to 36" and AP-2, but ''nerfs'' to only deal 1 mortal wound on a nat 6 to wound, instead of the 2 a standard blaster does, so you don't want this at all.  Give the same Dominus the Phosphoenix if you want a gun relic.
*'''Stratagems:'''
**'''Citation of Ruin (2/3 CP, Battle Tactic):''' Select one {{W40kKeyword|Extremis Sentinels}} unit during the shooting phase. This unit gains Big Guns Never Tire (shooting all guns while engaged, not just pistols) and ignores the -1 penalty for doing so with Heavy weapons. Costs 2 CP unless the unit had 4+ models, where the cost goes to 3 CP.
***Not ''useless'' on Kastelans, but clearly intended for Kataphrons.
**'''Pre-Calibrated Purge Solution (1 CP, Battle Tactic):''' Select one {{W40kKeyword|Extremis Sentinels}} unit wholly within your DZ during the shooting phase. Any time you shoot an enemy unit wholly within their DZ, the unit adds +1 to hit. 
***Tricky, because your units that can be targeted with this always rock at least one weapon with range 24" or less.  You probably won't get much use out of this.
**'''Bolster Defenses (2 CP, 1 Use Only, Strategic Ploy):''' Select one Area Terrain or Obstacle terrain feature in your DZ before the game begins. This terrain feature now counts as light cover or doubles the benefits of light cover if it already did. 
***Next-level worthless, because you have no Skitarii to take cover in the bolstered defenses, and your electro-priests have no interest in light cover.  You can use this to keep some standard servitors safe, but that's about it.
**'''Rad-Bombardment (3 CP, Strategic Ploy):''' If your warlord is on the field, you can order one orbital rad-strike per game. At the start of the Command phase, you can pick one point.  At the start of your ''subsequent'' Command phase, roll a d6 for every unit within 6", subtracting 1 for any {{W40kKeyword|Character}}s. On a 4+ the unit takes d3 MWs; on a 6 they also suffer -1 to their Toughness for the rest of the turn.
***Pretty bad, but you can potentially use it to frighten the enemy off an objective.

===Skitarii Veteran Cohort===

The opposite of book 1's army of renown. Instead of plodding weaponry, this army is far more mobile. Your Skitarii are now front and center as the fighty bastards they are. However, you'll need to sacrifice all the heavy firepower of things like the Kataphron and Kastelans are no longer a means for being walls.
<div class="mw-collapsible-content">

*'''Restrictions:''' 
**Your army has to be from the same {{W40kKeyword|<Forge World>}} and can only take {{W40kKeyword|Skitarii}}.
*** The only exceptions to this rule are the HQs; you can take ''only one each'' Dominus, Manipulus, Enginseer, and/or Technoarchaeologist in the army.
**Every detachment you take must include a Skitarii Marshal, and one of those Marshals must be your Warlord.
*'''Benefits:''' 
** All your {{W40kKeyword|Skitarii}} gain the {{W40kKeyword|Skitarii Veteran Cohort}} keyword, with your rangers and vanguard getting extra love in mandatory paid upgrades - +2 points per model and +1 PL per 10 models.
***Skitarii Rangers gain +1 to Leadership and Attacks, improve their Invulns to 5++, and count as being in light cover when fired at until they move each round. All in all everything you need to keep them a little better protected in the open so long as they camp.
***Skitarii Vanguard gain +1 to Leadership and Attacks, improve their Invulns to 5++, and roll an additional unkept d6 when advancing. When hit by a blast weapon, this unit always counts as being below 6 models, essentially telling cannons to eat hot irradiated shit before blasting them.
*'''Warlord Trait - ''Calculate without Diversion'' (Skitarii Marshal only):''' Rather than the classic Skitarii way of being dependent on data-tethers, this is just dependent on Doctrina Imperatives.  All of these abilities require the Warlord to be on the battlefield, unlike the standard 6 Skitarii warlord traits.
**Once per game when the Protector Imperative is active, you can use the Binharic Offense stratagem at a cost of one less CP.
**Once per game when the Bulwark Imperative is active, you can use the Bionic Endurance stratagem at a cost of one less CP.
**Once per game when the Aggressor Imperative is active, you can use the Expedited Purge Protocol stratagem at a cost of one less CP.
**Once per game when the Conqueror Imperative is active, you can use the Aggression Override Stratagem at a cost of one less CP.
*'''Relic - Cantic Thrallnet:''' During the command phase, one {{W40kKeyword|Skitarii Veteran Cohort Core}} unit within 6" of the bearer or {{W40kKeyword|Skitarii Veteran Cohort Core Data-Tether}} unit anywhere on the board can use any one doctrina imperative in addition to the one active for the rest of your army, even if it was already used earlier in the game and without preventing it from being used later. The Marshal's ability to ignore deprecation applies to only one of the two imperatives on this unit if you apply it, but you can choose which one.
*'''Stratagems:'''
**'''Aggression Override (1 CP, Battle Tactic):''' One {{W40kKeyword|Skitarii Veteran Cohort}} unit that made a charge gains +1A for all models for the following fight phase. Time to flatten with foot-claws and transonic shivs!
**'''Binharic Offense (3 CP, Battle Tactic):''' Select one enemy unit and two {{W40kKeyword|Skitarii Veteran Cohort Core}} units during the shooting phase. Until the end of this phase, the two units can ''only'' fire on this one enemy, but they add +1 to wound when doing so (meaning you get less benefit on Vanguard than Rangers, but it's still useful). Focus Fire FTW.
**'''Bionic Endurance (2/3 CP, Strategic Ploy):''' Use during any phase where a {{W40kKeyword|Skitarii Veteran Cohort Core}} unit would lose a wound. Until the end of this phase, the unit gains a 5+++ FNP, which is a nice gift. Cost increases to 3 CP if the unit has 10+ PL. Amusingly enough, the removal of {{W40kKeyword|CORE}} from Ironstriders and Dragoons means no units this strat can target can get over 10 PL, but you ''can'' reach 10 PL with a 20-skittle unit, since it will be PL 8 base + 2 for the mandatory Veteran Cohort upgrade.
**'''Expedited Purge Protocol (1/2 CP, Strategic Ploy):''' Use in the movement phase as a non-{{W40kKeyword|vehicle}} {{W40kKeyword|Skitarii Veteran Cohort Core}} (i.e. all of them, since there are no skitarii core vehicles) unit advances. This unit can then charge right after advancing. Only costs 1 CP when used on Rangers or Vanguard, otherwise it costs 2 CP.
