Scenario: Operation Overlord II

Operation Overlord II was the codename for the Invasion of North America, the massive European and East Asian operation that launched the successful invasion of the American Empire, or the former United States of America, and occupied Canada and Greenland. Launched by an alliance of over forty countries on September 2, 2048, the invasion was the largest in history, surpassing that of Operation Overlord I and Barbarossa during World War II, with a nearly 4,000-plane airborne assault preceding an amphibious and aerial assault involving more than 10,000 vessels. Nearly 500,000 troops crossed both the Atlantic and Pacific Oceans on throughout July and August, and more than five million European and East Asian troops were in North America by the end of October and the beginning of November. Although the invasion was postponed for several months out of fear of possible nuclear retaliation by the Americans, and the scale of North America coming into effect, the decision was eventually made at the Tokyo Conference in August 2047 to invade America. In recent years, the American Empire had become a pariah state amongst an increasingly open international community, preferring to be a rogue state. The empire had also become increasingly militaristic, making threatening moves towards several European countries, and being directly responsible for the Tehran Massacre in Iran in December 2045. This, coupled with increased tension with nearly all nations, besides a few similar states in the Caucasus, and increased cooperation between Europe and East Asia, particularly against the rise of China, rogue decisions were made to invade American-occupied North America, declaring the empire a threat to international security. Plans were finalized in July, with decisions for the Europeans to be assigned to land at sectors along the east coast, stretching from Greenland to southern Florida and the East Asians along the west coast at sectors that stretched from Alaska to Baja California. Both alliances were also divided, allowing small groups of countries to take certain sectors at a time and fight side by side. Meanwhile, the American Empire recognized an invasion was imminent, and Chancellor Donald Trump Jr allowed fortifications and artillery to be placed all around the two coasts, and fully militarizing the economy and the citizens. Longtime Generals Matt L. Harper and Joseph Tedder were placed in command of the East and West coasts respectively.

The subsequent battles that ensued along the coasts, with conflicts being seen in urban environments such as Los Angeles, Boston, New York City, etc. as well as beaches and rugged plains, have been characterized by the ferocious infighting of both sides during the battles, even by war’s standards.

Bombings
Bombing of the coasts of America began around ten minutes to midnight on September 1 with more than 10,000 European, including British, French, German, and Spanish, and East Asian, including Japanese, Korean, and Filipino, bombers attacking targets up and down their respective coasts and further inland. Evacuations were ordered in many coastal cities and towns, with Los Angeles, Seattle, Boston, Baton Rouge, and small villages in the Aleutians just some of the areas hit by bombardments. Pilots were given specific instructions on what to bomb, which included nuclear power plants and energy suppliers, as well as areas that were confirmed to hold sizable military garrisons. Officials were also tipped off by rogue revolutionaries.

European and East Asian bombers were sometimes subject to counterattack by the Americans, either by enemy bombers or anti-aircraft artillery. These largely remained ineffective though, and bombers continued unhindered,

In all, these bombardments by the Europeans and East Asians destroyed vital American supplies, particularly nuclear energy and garrisons. It is thought that if these bombardments never occurred, the American Empire might have launched a nuclear warhead.

Operations
Due to the sheer geography of the North America and the power of the American Empire, the actual invasion was to be conducted by a combination of amphibious and airborne operations to overwhelm and confuse the enemy. European and East Asian success depended on the establishments of secure lodgments from which to expand the beachhead to allow the buildup of a well-supplied force capable of breaking out. Prior to the invasion, the participating countries were divided into groups of four or more.
