[WH40k] How exactly does a ground invasion work? How does the fleet get Leman Russ tanks to planet side?

First you start with some light orbital bombardment to get a safe(r) corridor to the surface. Then you land on the planet. There are a variety of different sized drop craft available for deployment, from craft used to deploy a squad or two of troopers, to divisions worth of them. On some industrialized planets they can bring the whole mass conveyor down. The same applies with tanks. In the extreme end are the coffin ships of the Collegia Titanica which land the God Machines of the Mechanicus.
