Seeker Space Marines were a type of specialist Space Marine infantry squad used during the Great Crusade and Horus Heresy. Their principal role on the battlefield was to identify an enemy command structure and destroy them with well-placed surgical strikes while the battle rages. It is said that the Alpha Legion first perfected these specialists and with the Emperor's approval spread them to the rest of the Legio Astartes.
