Skitarii Marshal Sek-Ix-23

Skitarii Marshal Sek-Ix-23 is a playable Adeptus Mechanicus Commander designed to strengthen a formation from the centre of combat. The faction preview says he buffs both the unit to which he is attached and other units within range. Protected by bodyguards, he is also presented as the game’s only Commander composed of multiple models. These details establish a range-based support identity and unusual formation, but not exact mechanics. The source gives no buff values, radius, duration, model count requirement, weapon list, cost, attachment rule, durability or unlock condition.

Sek-Ix-23 was created as the formation-focused counterpart to Potentia Delta-9. Where Potentia offers remote scouting and flexible personal development, the Marshal is meant to stand amid allied forces and amplify combined firepower. His bodyguards make the Commander a multi-model formation, reinforcing that collective identity. The campaign preview also associates him with serving a Magos Dominus rather than following Potentia’s separate agenda. This is design and narrative context, not balance history; no prior version, changed buff, removed model, patch or tuning decision is documented.

The official use guidance is positional at a high level: keep Sek-Ix-23 in the thick of battle so his benefits can reach the attached unit and as many nearby allies as possible. The preview connects that placement to combined firepower and notes that bodyguards make the Commander difficult to neutralise as a single model. It does not publish the effect radius, which units qualify, whether benefits stack, the attachment input, a preferred formation or any upgrade sequence. A useful guide can explain central support positioning without inventing a composition, rotation or timing.
