what is provided to the Union if CSA invades past the border?

[Pocus]

In terms of units or anything (FS?)
Does it include owning a hex or actual unit presence?

TIA

[Aurelian]

Got a bunch of units in PA. Don't recall how many. 4 or 5 I think.

It is unit presence, not hex ownership. Also there is no 'border' in this sense, there are some specific lines in Pennsylvania and over Ohio, but it is not everywhere.
Check 'Volunteers' in strategy guide for details, or in decision scripts.

Pretty sweet deal for the Union I've seen the Vicksburg Divison/or Brigade fire but I haven't seen the South get the same treatment?

Thanks guys, quite a bunch of units indeed.
