In the two hundred and fifty years since the arrival of Hive Fleet Behemoth, Ultramar has been the bastion of the eastern fringe. Because of this almost constant exposure to the Tyranid threat Chaplain Cassius has formed a new Elite core of the Ultramarines, known as Tyrannic War Veterans.
The Tyrannic War Veterans are a great way to personalise a unit of Sternguard Veterans, especially if you collect Ultramarines. As Space Marines go, they have seen, fought, and killed pretty much every kind of Tyranid creature known to the Imperium, so they're well-versed in the art of war.
