If you listen to I think the Shield Brothers strike Cayde mentions that we took down the last two cabal command officers in the system. The message to the emperor or empire about Oryx and the destabilization of the Mars "beach head" should prompt a cabal support team if not the emperor himself to deal with Oryx. Assuming he hasn't heard the news of our defeat of Oryx. If we're to believe the Cabal go big or go home this support team should be MASSIVE.
