SPACE APARTMENT
Guys like this who demand surrender and are familiar with who they're asking surrender of always have another plan. Even if surrender was on the table, I don't think they'll consider the place their enemy took refuge as anything but hostile.
And I'm not too surprised at this. If you get Cosmo ask him if SAM could interface with whatever database this place might have, just to be on the safe side.
If they land, I agree it's going to be chaos. We're going to need to find leaders who can make some sort of on the go battle plans. Get people to get the civilians and the younger people into a safe zone, stuff like that.
I'm ground based myself, I never learned how to fly and SAM wasn't designed for it and it might take him a bit to figure it out. If this place had some drones I could interface with those and send them out to run some interference.
