Paragons of Honor

If every unit from your army has the IMPERIAL KNIGHTS keyword, then after you have sworn 2 Oaths for your army, you must, if you have this Tradition, swear one additional Oath. This Oath applies to all models in your army with this Tradition (i.e. that Oath’s Pledge, Troth and Chivalric abilities only apply to models in your army that have this Martial Tradition).
