As far as I know the 2005 BRAC was the only time it was seriously suggested that Rock Island could be on the chopping block.
I've been toying with the idea of the facility being closed for political reasons and the successor to Blackwater security (they change names so often) starting their
Grizzly_APC production on the Island. With my fictional BW CEO being from the quad cities and politically connected in Illinois.
I'm trying to throw a REALLY strong wildcard into the mix for a 2013 Illinois scenario. You would have an semi elite force, with a unbelievably defensible location and gobs of equipment to work with.
I could just make the US forces on the Island declare themselves a "free city" like Krakow, but I like the idea of the base closing in 2006 and being redesigned for a quasi civilian/military tenant.
Glenview NAS and Fort Sheridan are other options for the same BW facility. When they were closed they became mixed use civilian facilities, but each is too close to Chicago for my goals.
