The MEC and China have coordinated the largest-scale invasion of North America in history, with a two-pronged attack designed to fracture and confuse the American defenses.
China has cut a deal with Russia to use its east coast as a launching point for an assault across the Bering Sea into Alaska, where it hopes to secure the port of Valdez before securing oil fields further inland. With a strong foothold and access to fuel, China plans to continue south through Canada, securing the Alberta oil sands before continuing toward California. The American forces, already stretched thin from the wars in Asia and the Middle East, are forced to leave bases undermanned in the south to deal with the Chinese threat in the north.
Meanwhile, the MEC has been slowly building up men and supplies in various South American and Caribbean locales for an invasion across the eastern coast of the United States. Severely undermanned, the US forces put up a fierce battle, but it's not long before the MEC have secured beachheads all along the East Coast. The majority of MEC forces have landed to the north and south of Washington DC. The MEC's first objective is to secure major highways and arteries leading into the capital. Once the MEC controls the supply routes, their assault on the US capital will begin!
