Diego Garcia is a tropical, footprint-shaped coral atoll located south of the equator in the central Indian Ocean. It was used in 2001 as a base for B-1 bombers, for the bombing campaign in Afghanistan. It now serves as the main base of operations for the Non-biological Extraterrestrial Species Treaty, aka NEST and the Autobots. Also located on the island is a burial sight for the fallen Autobots, such as Jolt and Arcee.
