The Fire Angels are a Space Marine chapter created from Ultramarines gene-seed. They fought on the loyalist side during the Badab War. In one incident during the war, the rebel Astral Claws launched a suicidal counter-attack, in which a squadron of Rhinos broke through an Imperial salient to the Fire Angels' lines and detonated a virus missile, causing more deaths in one day than the Fire Angels had suffered in the war so far.
