[WH40K] So some space marines just decided to make my home planet into an outpost in their war against the Tau. How do I tell them to politely leave, and take the city they just dropped from orbit with them?

You are lucky Imperial Citizen!

Few are those who get to see our glorious Emperor's Angels of Death and not be greeted with righteous fury.

As for your request... it is impossible.  Your planet is needed for the Crusade against the filthy Tau xenos.  You should be thankful that you and your planet has been chosen for such privileged service.
