I can highly recommend this ...
Its a full playable level of Battlefield 2 in the gulf of Oman, multiplayer and single player, youll need a decent PC to run it.
It features carrier launched planes and helicopters (attack and transport), APC's, T90's, M1A1's, Jeeps, Airfield planes and helicopters, boats, etc etc!!!
You can even swim in this.
Its an older game but one of the best multiplayer games i have ever played (currently modding a server for a guy, these are pix of things ive added)
