The Dragon Unleashed is the first mission in the Chinese campaign of Zero Hour. The operation marked the beginning of the Chinese liberation of Europe.
Prior to the mission the GLA made a daring attack on the USA's European Central Command in Stuttgart. The assault was successful because the GLA used captured Chinese weaponry that gave the terrorists the much needed firepower to overrun the American defenses and capture the US base. In order to quickly repel the GLA, Chinese command ordered a nuclear strike on the GLA-captured stronghold. The GLA's celebrations were cut short when a nuclear missile decimated the occupants and a large portion of the American base. There were a few survivors who escaped the blast, necessitating a ground assault on the GLA remnants.
