Fort Bragg Military Base, USA

The base was first announced during WWII to test and train tank destroyers. The post is known as 'The Great Place' because of the quality of standard it maintains. Fort Bragg is the only post in the United States which can support two full armoured divisions.
Edwards Air Force Base
I think it's more likely to be a base like Saudi Arabian National Guard's Kashmalan base in Riyadh... It's 28 miles in length and houses everything on an extreme level.
The SANG are the Kings own private army, not part of the main Saudi Army. While they don't have tanks etc. they have literally thousands of APC's, massive advanced technical training facilities and it's effectively a city unto itself.
The SANG was initially trained by the US military and tech/comms etc. supplied by the British.
