Friendly ULTRAMARINES units benefit from this model’s Astartes Banner ability if they are within 9" of it instead of 6".
Astartes Banner:
units within 6"of any friendly ANCIENTS add 1 to their Leadership. In addition, roll a D6 each time a INFANTRY model is destroyed within 6" of any friendly ANCIENTS, before removing the model as a casualty. On a 4+ that model musters one last surge of strength before succuming to its wounds; it can either shoot with one of its weapons as if it were the Shooting phase, or make a single attack as if it were the Fight phase.
