I have been trying to be more authentic with my Middle East missions and I too would like to see a island more on these standards. I currently use: MadAussie's Iraq Island; Jelalhabat Island by Umf; and CAT's Central Afghanistan for missions in the middle east.
Just to make the Iraqi Island cooler, I would download AGS City Construction and Industrial Kits to make an authentic Iraqi City. Other addons I use are the Taliban Addon to put some more Mosques and Minerets around the town and some destroyed T-72s and Mi24's as remnants from Operation Desert Storm. In realism, Iraq wouldn't have too many skyscrapers except in Baghdad and other large cities.
I would like to find some OEF addons to make my Invasion of Iraq authentic. Maybe tons of posters of Saddam and some Baath Party prophaganda. I saw a while back that a team was making a Iraq addons and campaign pack with tons of stuff including Realistic Highway Signs for Saddam International Airport and the city of Baghdad all written in Arabic, Oil Refineries and Pipelines, Statues of Saddam and Palaces. If anyone knows about this, let us all know.
