Changes

At the time of the [[Great Crusade]], it was customary for Ultramarines marked out for censure to bear red markings on their helmets. During the Battle of Calth, Guilliman ordered that the squad leaders accompanying him aboard the orbital platform paint their helmets red; because the Word Bearers' attack had shredding shredded the Ultramarines' normal command hierarchy and squad unit organization, and because [[vox]] communication was unreliable, Guilliman wanted clear, visual cues for the Ultramarines to follow. Furthermore, he added that after Thiel's heroism of the day, red markings would be badges of honour, instead of censure.{{Cite This}}
