Learn visibility BEFORE purchasing units??

[Spledge]

I'm working my way through my first campaign and have noticed that the Mission Statement does not included the scenarios Visibility.

I'd prefer to know the visibility BEFORE making purchases as they can change according to conditions. How can I learn of that condition before purchasing Supporting Units?

Thanks!!

On the support points purchase screen, click the "View map" button. The battle length and visibility are shown in the info panel at the bottom of the screen.
