In the description of the video we can read:

The Marianas archipelago is approximately 2,000 km south of Japan, and includes Guam, Rota, Tinian, Saipan, and a score of lesser islands. Home to Andersen Air Force Base on Guam, the Marianas serve as the key US strategic asset in the western Pacific.

And we even get a very quick sneak peek of the AH-64 Apache for the sim! Check out the video below.
