It is a work in progress by 37mm over at the BFC forums. Aquila-CM provided the Huey helicopter (flavor object) in the screenshot. Sgt. Squarehead made the map. I just tested one of the scenarios for the campaign they are working on. Tentatively named Heaven and Earth. There is a thread about it over at BFC. I would link it but the BFC forums are down. Aquila-CM also has a thread over there with dozens of very cool mods that can be downloaded. I think both the mentioned threads are in CMSF 2 scenario & Mods forum. Below are a few more screenshots both of the Southeast Asian mods and Aquila-CM mods in general.
