An army that includes one or models with this special ruke may take up to three Thallax Cohorts as a non-Compulsory Elites choice in the same detachment as the model with this special rule - these units may not select a Dedicated Transport of any kind. Any models in a Thallax Cohort which are included in an army due to this special rule gain the same Legiones Astartes (X) special rile as the Legion Forge Lord it shares a Detachment with, but may not select any Legion specific Wargear or other options.
