The Infiltrators are Primaris Space Marines from the Vanguard forces, trained to slip behind enemy lines, jam communications, and sabotage key targets. They’re the stealthy edge of a Chapter, hitting where the enemy isn’t looking.
What the Infiltrators do
Infiltrators specialise in disruption. Their Omni-Scramblers, mounted on their backs, intercept and jam enemy signals across a wide spectrum, cutting off communications. When they finally strike, they pop smoke grenades and advance with disciplined volleys from marksman bolt carbines.
Because they spend long stretches behind enemy lines, they’re drilled hard in survival and self-sufficiency. They wear Mk.X Phobos Armour, which trades heavy plating for mobility and stealth.
- Role: disrupt communications, sabotage targets of opportunity
- Gear: Mk.X Phobos Armour, Omni-Scramblers, marksman bolt carbines, smoke grenades
- Training: extensive survival and self-sufficiency for extended operations
Types of Vanguard Infiltrators
Infiltrator squads can include specialists who broaden what the unit can do. A Commsman acts as a strategic nexus, speeding up vox-exchanges and intelligence sharing. A Helix Adept, a trained Apothecary, keeps the squad alive and recovers gene-seed.
Saboteurs rig targets with melta charges, super-krak munitions, and even anti-plant canisters. Voxbreakers scan for threats and break into enemy communications for intel. Veterans, armed from their Chapter’s rarest armouries, stalk foes like armoured ghosts. Warriors bring speed and aggression, while Sergeants lead with tactical skill.

Where they fit in the lore
Infiltrators are part of the Vanguard Space Marine forces introduced with the Primaris Marines. They often operate alongside Incursors in Phobos Strike Teams, as seen in Kill Team: Moroch.
Their approach contrasts with the massed firepower of battleline squads: they win by cutting enemy coordination and hitting weak points before the main force arrives.
