Editing Warhammer 40,000/10th Edition Tactics/Space Marines (section)

===Gladius Task Force===
<div class="toccolours mw-collapsible mw-collapsed">
The Index's general-use detachment. It's focused around single-use Doctrines that can generally influence the way your army operates for the turn. That said, you also have stratagems that allow you to use more localized Doctrines without worrying about usages.
<div class="mw-collapsible-content">
====Special Rules====
*'''Combat Doctrines:''' At the start of your command phase, you can pick one of these to apply to all {{W40Kkeyword|adeptus astartes}} units in your army until the start of your next Command Phase, and each can only be picked 1/battle.
**'''Devastator Doctrine:''' Your army can always shoot after advancing, which is actually best on ''non-heavy'' weapons that lose nothing from Advancing rather than Remaining Stationary, meaning this buffs your Devastator Squads and the like ''least''.  Because GW is bad at rules, this ''doesn't'' add the ''Assault'' USR to all of your guns (instead applying the definition of it directly to every gun).
**'''Tactical Doctrine:''' Your army can shoot and charge after falling back, which primarily buffs units with {{W40Kkeyword|fly}} because they're better at falling back.
**'''Assault Doctrine:''' Your army can charge after advancing.

====Stratagems====
<tabs>
<tab name="Battle Tactic">
*'''Armour of Contempt (1 CP):''' One of the few rules we welcome being busted to a stratagem. One unit getting attacked reduces the AP of any attacks they get by 1, which will mean a lot more with how much AP got nerfed.
*'''Honour the Chapter (1 CP):''' One unit gets ''Lance'' on their melee weapons, making this only useful if the unit had just charged. In addition, if you have Assault Doctrine active, these weapons also improve their AP by 1.
*'''Storm of Fire (1 CP):''' One unit gets ''Ignores Cover'' on all their guns and improves the AP of their guns by 1 if the Devastator Doctrine is active.
</tab>
<tab name="Epic Deed">
*'''Only in Death Does Duty End (2 CP):''' If an enemy hits and kills one of your models in melee before they can fight back, that model can get one last swing before going down.
</tab>
<tab name="Strategic Ploy">
*'''Adaptive Strategy (1 CP):''' One unit gets to pick which doctrine it wants active, regardless of what anyone else is using and whether you had used it before. Remember what we said about Adept of the Codex being pointless? This is why.
*'''Squad Tactics (1 CP):''' When an enemy moves within 9" of a {{W40kKeyword|Infantry}} or {{W40kKeyword|Mounted}} unit, that unit can move d6" in any direction. Using this while under Tactical Doctrine makes that movement a flat 6" and thus better for getting the squad into position.
</tab>
</tabs>

====Enhancements====
*'''Adept of the Codex:''' {{W40Kkeyword|captain}} only, and absolute trash.  When you would pick a Doctrine for your army, you can ''instead'' select the Tactical doctrine and force it to be on the Captain's unit even if you've already used it; [[Wat|the downside for this is you didn't pick a doctrine for your army, so the entire rest of your army has to go doctrineless]].  You should absolutely never field this.
**Remember you can Rites of Battle to use Adaptive Strategy for free on the Captain's unit. So yes, you can either take Adept of the Codex and have your entire army go doctrineless in exchange for the Captain's unit having the Tactical doctrine...or have your entire army use a regular doctrine and the Captain's unit have any doctrine for free without consuming an enhancement slot. Hard choice to make.
*'''Artificer Armour:''' Bearer gets 2+ and 5+++. Always useful on anything.
*'''Bolter Discipline:''' While the bearer is leading a unit, ranged weapons equipped by models in that unit have ''Sustained Hits 1''. In addition, while the bearer’s unit is under the effects of the Devastator Doctrine, each time a model in that unit makes a ranged attack, a successful unmodified Hit roll of 5+ scores a Critical Hit.
**Note that the 5+ crits happen to the bearer regardless, but the Sustained Hits rule requires them to lead a unit, so you should never put this on a non-Leader.
**An example compelling combo with this: Take a Primaris Lieutenant with this (meaning the attached unit also gets '''Lethal Hits''' and is functionally always in the Tactical Doctrine). Attach a Primaris Captain with Plasma Pistol.  You can now spam the Adaptive Strategy stratagem to maintain the Devastator Doctrine on this unit, and when shooting your Oath of Moment target, you can (and should) re-roll 1-4 hit to fish for 5s and 6s, which will get you 1 hit that auto-wounds (from the Lieutenant) and 1 that must roll to wound but can re-roll failures (from Oath of Moment), and if you pay 1 CP for Storm of Fire as well, you'll also have ''Ignores Cover'' ''and'' improve your AP by 1.  
*'''The Honour Vehement:''' Bearer gets +1A and +1S to melee weapons, +2A and +2S instead while under Assault Doctrine. Best suited for any heroes with ''Extra Attacks'' like Gravis Captains with fists and Techmarines.
