SPECIAL RULES: And They Shall Know No Fear, Chapter Tactics, Move
Through Cover (Centurion Assault Squad only), Slow and Purposeful, Very Bulky.
Slow and Purposeful
Many warriors are steady but sure, slow to advance but no less deadly for it.
A unit that contains at least one model with this special rule cannot Run, Turbo-boost,
move Flat Out, perform Sweeping Advances or fire Overwatch. However, they can shoot
with Heavy, Salvo and Ordnance weapons, counting as stationary even if they moved in
the previous Movement phase. They are also allowed to charge in the same turn they fire
Heavy, Ordnance, Rapid Fire or Salvo weapons.
