Image Description: [Phillipi Tarse, Chapter Master of the Mantis Warriors. Tarse was legendary in the Mantis Warriors long before assuming Mastership over the chapter. For centuries Tarse was responsible for the defense of the home world which, due to it's location near the Maelstrom and the many enemies the chapter had made nearby, was under heavy assault each time the chapter mobilized in any significant fashion. His hand picked, elite defense force were masters of defensive action... and while they used the full range of combat tactics they became known as the "Snipers of Tranquility" as their strikes against would-be attackers would have all the surprise and finality of a snipers bullet. All members of the Tranquility Snipers color their equipment in a unique pattern that is respected throughout the Imperium and feared by it's enemies.
Due to his unique responsibilities, Tarse was the only highly placed Mantis Warrior commander to not take part in any aggressive actions against another chapters during the Badab Rebellion (though he did defend Tranquility with unmatched tenacity, ferocity and guile). As such... he was the natural choice to lead his chapter through the darkness of the crusade in the hopes of eventually regaining it's status as a respected member of the Adeptus Astartes. He is also the only high-ranking Mantis Warrior commander who is fully trusted by the Inquisition or other Space Marine Masters.
