Here is a map for ATF and Raging Tiger of the city of Fallujah. The "water" attribute for the river has been removed so it can be used in ATF, but the river still has a "tank ditch" characteristic that SHOULD prevent vehicles from crossing anywhere but bridges.
Fallujah Map for ATF and RT
Unzip to your "Data" folder in your ATF or RT directory, then you can create your own scenario.
Let me know if you have any problems!
