The Gobi Campaign was a military operation conducted by the United States Armed Forces during the beginning of a full-fledged retaliatory American invasion of China in response to the Chinese invasion and subsequent occupation of Anchorage, Alaska initiated in 2066. It took place in or near the Gobi Desert.
The military objective was to invade the Gobi Desert, and eliminate the Chinese strongholds there. A heavily modified sniper rifle, the Gobi Campaign scout rifle, was used during the operation (it is not known if this rifle was a standard weapon or not). The outcome of the campaign is unknown.
The Gobi Campaign is mentioned only in Fallout: New Vegas.
