Eliminators are Vanguard Primaris Space Marine snipers that utilize a range of exotic and deadly ammunition tailored to their target. On the battlefield they are deployed as Fire Support Squads.

Eliminator Squads utilize an even more stripped-down version of the Mk.X Phobos Armour, allowing them to operate with maximum stealth. These warriors serve as dedicated marksman and fire support specialists that haunt the shadows of the battlefield seeking out targets of opportunity and bringing them down from a range.

"Of the Tactical Space Marine, bedrock of his Chapter and paragon to his brothers, I shall tell thee.

He shall be steeped in the lore of battle and schooled in all manner of weapon and strategy. With combat blade, boltgun and grenade he shall assail the foe. But these are mere tools: a Tactical Marine's true weapons are his courage, his wits, and his dedication to his brothers.

He will bring his foe to battle in a manner and time of his choosing, never himself caught unready or ill-prepared for the task at hand. In defence he shall be stalwart as the mountain, a bulwark stood firm against the enemies of Man. In attack he shall strike with the wrath of the Immortal Emperor, felling the foe without mercy, remorse, or fear. "
