The original map, The Island was created by RavenousNC. You can find and download this map here, https://www.ghostrecon.net/files2/index.php?act=view&id=596
I really like this map, but I find the sniper who shoots at your base from behind a tree on a roof at the beginning very frustrating, because you can't see this sniper yourself and are immediately shot by them.

That's why I removed this sniper with the map editor and gave the map a different name, The Island - changed.
The map is attached here and can be downloaded. Unzip the map and save it in your GRAW_gamefolder\custom_levels folder.
