Where Strike and Terminator squads seek the enemy at close quarters, the Purgation Squad holds back to rain destruction from afar. Its members are trained in the mastery of heavy weapons, from long-ranged firepower to the searing embrace of the incinerator, and they position themselves to command the field of battle.
Even at range, the warriors of a Purgation Squad remain psykers of considerable strength, and their combined focus can lend precision and fury to their fire. Against massed daemonic hordes, their weapons carve bloody paths through the enemy, banishing scores back into the Warp with each disciplined volley.
The Purgation Squad exemplifies the methodical ruthlessness of the Chapter, for the Grey Knights understand that some enemies are best met not with the blade but with an overwhelming curtain of cleansing fire. Where they hold the line, no daemon may advance unpunished.
