Calato's Kill Team came under the service of Inquisitor Kryptman, though he spent more time preparing recaff than actually fighting. However, he finally got to see some action when the Tyranids first entered the galaxy. Calato helped repel Genestealers aboard Kryptman's ship, and was prepared to fight an onslaught on the world that they were defending.
Calato was very wary about teaming up with the Blood Ravens, as he had heard rumors of their kleptomania.
