OK, here we are.
The next one is one of the central pieces for my "scenario".
Things as the ventilation turbine and the missiles silos are what you see on the surface of a gigantic subterranean complex by AdMech (and Imperium).
In this complex there is, obviously, also a subterranean hangar with tanks and robots.
So the next piece is the "exit point" of this hangar. Basically another bunker, that this time has been built around the fortified sliding door which is the exit for the tanks (they went out tnx to a double conveyor belt).
On the rear side of the bunker, there will also be a lifting platform to take on the surface things as Kastelan robots.
