Region: The East Pacific
I gotchu, but wouldn't you need at least a colony in the desert to make desert warfare systems?
Otherwise, it's really difficult to test vehicles, since you either have to rely on another nation/company to not steal your blueprints as they test for you, or send the vehicles to the desert, test it briefly, then fly all the way back. That's a large waste of gas and helicopters for a short four hour test, never mind you have to test vehicles multiple times to ensure functionality. >.<
