The Praetors of the Phoenix have bonds to their brothers-in-arms stronger than any other warriors in the whole Imperium. As a show of solidarity before battle, their brothers will mark their armour with a unique symbol that will signify their unity and to show that the Brotherhood of the Chapter comes before anything else. Having this bond means that the Praetors of the Phoenix fight in complete unison, no commands are needed or given as they all work as a collective and conquer their enemies without any need for discussion. The warriors will work towards the Chapters common goals without any disputes, knowing that they are protecting their Brotherhood at all costs.
