Allied forces and planetary garrisons

Where this topic stands

PC Gamer, reporting on 2 September 2026 on a Gamescom session playing the Ultramarines, describes ordinary Planetary Defence Force soldiers defending its settlement. The player could not recruit those garrison units in that preview. In two separate battles, an Astra Militarum army was already fighting the Orks when the player arrived, as an allied force outside the player’s direct control. Battle product owner Dave Petry is also quoted discussing experiments with gaining support to bring units into battle. These are observations of a preview build and remarks about a concept being explored; the reviewed material does not explain how they connect in the eventual campaign.

Context and precedents

The Gamescom preview separates three kinds of force around the player’s army: a settlement garrison, an allied army already engaged in battle and units that might be brought along through a support system. The first concerns defence of a location; the second concerns participation in a particular fight; the third is a concept Petry described as being explored. These are different roles even when the forces belong to the same side. Understanding who recruits, moves and commands each one is more useful than assuming they share a single control system.

Playing the Ultramarines in the Gamescom preview, PC Gamer reports a settlement garrison of ordinary Planetary Defence Force soldiers that the player could not recruit. In two battles, an allied Astra Militarum army was already fighting when the player arrived and could not be directly controlled. Battle product owner Dave Petry separately describes experiments with gaining support to bring units along into battle. The reported preview conditions and that developing concept remain distinct.

What has actually been shown

The hands-on account provides two concrete limits in the preview: the player could not recruit the garrison’s troops and could not command the allied Astra Militarum army already fighting. Petry’s separate comments concern experiments with obtaining support and taking units along. Those observations do not yet form one documented campaign system. A further demonstration would need to show where a support decision is made and whether it changes the units available, their movement or their control during battle.

What to watch next

The useful question is what influence a player has over an allied force that cannot be directly commanded. In the preview, the allied army was already fighting when the player arrived. It remains to be shown whether the player can request support, coordinate an arrival or choose an objective, and whether those decisions belong to the campaign or the battle. Petry’s comments about gaining support identify a concept under discussion, not a documented currency or set of orders. Further examples need to distinguish an arrangement built for the demo from a repeatable system the player can use. Information correct as of 5 September 2026.
