I suggest selecting the Stationed Unit's medallion then right clicking on where you want them to go...MUCH more useful than using the 'Eject from City' button.
If you want that to be 'intuitive' for us text/keyboard focused folks, might help to make that selected unit appear on the cloth map.
I would never in a million years have thought to right-click after missing that tiny, annoying button and unknowingly having selected the unit.
But then I'm still hoping to see keyboard nav work eventually, and I know that's a 'niche' thing...
