Controlled and monitored from orbit by Adeptus Mechanicus Tech-Priests, the Skitarii War Cohort has been the last thing seen by entire civilisations. A crushing display of force comprising three entire Battle Maniples, the War Cohort is a fearsome foe to be underestimated at peril.
This huge, awesome bundle contains everything needed to make the War Cohort, found in Codex: Skitarii. It contains a staggering ninety-nine models - thirty Skitarii Vanguard, thirty Skitarii Rangers, fifteen Sicarian Ruststalkers, fifteen Sicarian Infiltrators, three Sydonian Dragoons, three Ironstrider Balistarii and three Onager Dunecrawlers. Each of these miniatures features various posing options and weapons.
