From Kanttorie's post in the other thread:
Thank you! Okinawa map is made by CM Terrain Team:
Textures (lanscapes and coastlines) by Squirrel
Clipboard map by Dux
Historical details and reference pictures (airfields and skins) by Brady
Satellite map and elevations by Camouflage
I only built the terrain and used the great material what this awesome team created! I also used some skins (houses, flames etc.) from the great looking Slot map...
