Yeah, I think I can do that. May not be fancy, but such is the prototype life.
I increased the clickable area on Countries for this prototype, so I would advise just clicking a little further away from the other Units. It should still work correctly. (Compromise idea: Some basic UI outline of the clickable Country area, so you know what exactly you're clicking on.)
It's something to keep an eye on when we get to proper playtesting.
