Augurium Task Force: The 11th-Edition Grey Knights Redeployment Detachment

From the second battle round onwards, at the start of your Movement phase, if you did not select the maximum number of GREY KNIGHTS units for the Gate of Infinity ability at the end of your opponent's previous turn, you can select one Grey Knights unit on the battlefield that could have been selected using Gate of Infinity, remove it from the battlefield and place it into Strategic Reserves.

The conditional is the whole design. It only fires if you left capacity unused. At Strike Force the army rule lets you take up to three units; if you take all three, this rule does nothing. So the detachment is quietly asking you to hold one slot back every turn, which is a genuinely interesting constraint: you are trading breadth at the end of your opponent's turn for a targeted extraction at the start of yours.

The designer's note is the part worth memorising, because it spells out a sequencing trick that is easy to miss and hard to argue with once you know it. Your unit keeps its position on the battlefield through the end of your Command phase, which is when objectives are scored, and only then goes into Strategic Reserves at the start of your Movement phase, to be set up somewhere else in your Reinforcements step.

In plain terms: you score the objective, and then you leave. The unit is on the marker when scoring happens and gone before your opponent can retaliate. In a thirty-model army that cannot afford to hold ground by force, that is the single most valuable trick in the faction.

Note the same eligibility conditions as the army rule apply, so a unit within Engagement Range of an enemy cannot be selected. This detachment does not rescue units from combat any more than the army rule does.

Six, all 1CP, and three of them put a unit into Strategic Reserves. That repetition is the detachment's thesis.

• Aggressive Anticipation (your Shooting or the Fight). Battle Tactic. Target one GREY KNIGHTS PSYKER unit that has not shot or fought this phase. Your unit's attacks can re-roll hit rolls. Faction Pack v1.1 rewrites this stratagem's Effect section, and the current wording is a plain full re-roll with no conditions attached. That is a very strong effect for one command point, and it applies to shooting or melee at your choice of phase. If you have read an older description with extra conditions on it, this is the current version.
• Appointed Hour (your Shooting or the Fight). Battle Tactic. Target one GREY KNIGHTS PSYKER unit that has not shot or fought this phase. Until the end of the phase, an unmodified Hit roll of 5+ scores a Critical Hit. Widening the critical range from 6s to 5+ roughly doubles your critical hits, which matters enormously alongside anything keyed to them. Pair it with a weapon or partner detachment granting Sustained Hits or Lethal Hits.
• Redirected Strike (end of your Command). Epic Deed. Target one GREY KNIGHTS PSYKER unit not engaged. If it has Deep Strike, it can be placed into Strategic Reserves. The designer's note is explicit that this exists so you can score an objective at the end of your Command phase and then remove the unit, which is the same trick as the detachment rule from a different angle.
• Mirage of Echoes (Reinforcements step of opponent's Movement). Strategic Ploy. Just after an enemy unit is set up, target one GREY KNIGHTS PSYKER unit within 12 inches of it and not engaged. If it has Deep Strike, it can be placed into Strategic Reserves. The reactive escape: when something drops next to your squad, the squad simply leaves. It answers the standard punishment for a Grey Knights unit caught alone.
• Necessary End (Fight). Epic Deed. Just after an enemy selects targets, target one GREY KNIGHTS INFANTRY unit that was selected. Each time a model in your unit is destroyed, if it has not fought this phase, roll one D6; if the result is greater than the current battle round number, it is not removed and can fight after the attacking unit finishes. The battle round condition makes this excellent on turn one and nearly useless on turn five, which is unusual and quite elegant design. Use it early or not at all.
• Forewarned Evasion (opponent's Shooting or the Fight). Epic Deed. Just after an enemy selects targets, target one GREY KNIGHTS WALKER unit that was selected. Until the end of the phase, attacks against your unit subtract 1 from the Hit roll. Note the WALKER restriction. This only protects Dreadknights and Dreadnoughts, and it is dead weight in a list with no walkers. Check before you count on it.

Four, all Grey Knights model only, which is unusually permissive.

• Doomseer's Amulet (25 pts). Each time the bearer's unit is set up in your Reinforcements step, select one enemy unit within 12 inches of and visible to the bearer; it must take a Battle-shock test, subtracting 1. This detachment sets units up in the Reinforcements step constantly, so the trigger fires more often here than it would in any other detachment in the faction. Battle-shock strips Objective Control, which turns an arrival into a scoring play.
• Shield of Prophecy (20 pts). Once per battle, at the start of the battle round, until the end of that battle round add 2 to the Toughness of models in the bearer's unit. Two points of Toughness for a whole battle round moves most incoming weapons a full wound bracket, and choosing the round is the skill. Save it for the turn you know the alpha strike is coming.
• One Foot in the Future (15 pts). When this unit ends an ingress move, you can use this ability; if you do, the unit can make a normal move of up to D6 inches, and until the end of the turn it is not eligible to declare a charge. Faction Pack v1.1 rewrites this enhancement wholesale, so the wording above is first-party. It keys off the ingress move, which is exactly what Gate of Infinity grants returning units, so it extends every redeployment this detachment is built to make. The charge restriction is the price, and it means this is for a shooting unit rather than an assault one.
• Grimoire of Conjunctions (10 pts). Once per battle, at the start of the Fight phase, until the end of the phase add 4 to the Strength of melee weapons equipped by the bearer. Four points of Strength on one character for one phase is enormous, typically taking a Nemesis weapon from wounding a heavy target on 5s to wounding on 3s. The cheapest enhancement in the detachment and a genuine assassination tool if you time it.

(Points come from the Munitorum Field Manual and move with updates; confirm in the app.)

• [Strike Squad](/40k/boxes/warhammer-grey-knights-strike-squad-new) is the unit you cycle. This detachment is about scoring an objective and then leaving, and cheap Battleline is what you want doing that rather than an expensive centrepiece.
• Interceptor Squad is fast, deep striking and eligible for every Reserves stratagem here, which suits a detachment built on repeated arrivals. No box is linked, because our catalog has no exact Interceptor Squad entry.
• [Brotherhood Terminator Squad](/40k/boxes/warhammer-grey-knights-paladin-squad-new) holds the ground you are not cycling. A list that redeploys everything holds nothing, and this is the detachment most at risk of that mistake.
• Nemesis Dreadknight is the only way to use Forewarned Evasion, which is WALKER only. Without a walker in your list that stratagem is dead. No box is linked, because the catalog has no exact entry for the non-character Dreadknight.
• [Grand Master Voldus](/40k/boxes/warhammer-grey-knights-grandmaster-voldus-new) is a Psyker character able to carry any of the four enhancements, all of which are Grey Knights model only. His Sanctuary ability is rewritten in v1.1 to grant Stealth and impose -1 to hit in melee.

No Unique Tag, so all three 1 DP detachments are legal for exactly 3 DP.

• [Immaterial Interdiction](/40k/armies/grey-knights/detachments/immaterial-interdiction) (1 DP) is the thematic twin. Both are repositioning detachments and both carry the Reconnaissance force disposition. One recycles units through Reserves at the army level, the other repositions a squad at the squad level after it shoots. Sharing a Force Disposition is not a tag clash, and Grey Knights have no tags at all, so this is perfectly legal.
• [Fires of Purgation](/40k/armies/grey-knights/detachments/fires-of-purgation) (1 DP) is the pairing we would actually build, and it gets its own page. Prescient Redeployment gives a static gun platform an escape route, which is the one thing a Purgation Squad most lacks in an army built to teleport away from trouble.
• [Argent Assault](/40k/armies/grey-knights/detachments/argent-assault) (1 DP) combines a detachment full of ways to put units into Reserves with a hammer that wants to arrive next to something tough. Grimoire of Conjunctions on the character leading the Paladins compounds with Dauntless Champions in the same turn.

Take it when you enjoy the positional game more than the killing, and when you are willing to play a disciplined objective cycle rather than committing to fights.

Be clear-eyed about the limits. The detachment rule only fires if you underused the army rule, which is a real cost that a careless player will never pay attention to and therefore never collect on. Forewarned Evasion is dead without a walker in your list. Necessary End is nearly worthless after turn two. And the detachment's biggest failure mode is thematic: a list that is always redeploying is never holding, and Grey Knights lose more games to being out-scored than out-fought.

Sample gameplan: pair with [Fires of Purgation](/40k/armies/grey-knights/detachments/fires-of-purgation) (1 DP) for exactly 3 DP. Deliberately select two units for Gate of Infinity rather than three at Strike Force, so Prescient Redeployment is live every Movement phase. Put Doomseer's Amulet on a character in the squad you cycle most, so every arrival forces a Battle-shock test at -1. Score with a Strike Squad at the end of your Command phase, then remove it at the start of your Movement phase and set it up somewhere new. Hold Shield of Prophecy for the alpha strike, and keep a Brotherhood Terminator Squad parked on your home objective so the list actually holds something.
