This is Saar River, 2nd beta, released for testing on September 30, 2006.
The map was created by John Benson, Pfc. "Darth" Brooks of the 3rd ID. http://www.3rd-infantry-division.net/

There is a thread about the map's creation there.

There is a newer version in the works and it should be ready (and finally finished) in about two weeks.
