I have your 653H scenario in the community pack. That's also historical, I assume?
Yes, 653H is Historical, but also includes other gameplay changes. 653Hi contains Historical OOB's with no gameplay changes.
So the stock scenarios don't include historical set-ups?
Not strictly speaking. They are ok, but if you are OCD for Historical Unit Names and Orders of Battle like I am, you will want a little more detail. 653Hi has that, 653H has all that and a little more, 653N has all that plus a severe Naval Model.
where do I put the data txt files (3 of them) and the free units txt file?
Those are Text Files, for your enjoyment or not, put them where you want
