In the wake of the upheaval in Russia, a series of small brushfire wars erupt around the world. One of the deadliest is a resumption of hostilities between Ethiopia and Eritrea, which is spurred by a coup in Addis Ababa. Armed with Russian weaponry, the Ethiopian military, led by a man named Colonel Tesfaye Wolde, makes a successful grab for the Eritrean coastline. The Ethiopian offensive sends the Eritrean forces into hurried retreat. Shipping on the Red Sea is disrupted, and relief efforts in the interior come crashing to a halt. At the request of the Eritrean government, and in order to advert a humanitarian crisis, an international coalition is built in response.The Ghosts are the spearhead of this force. Their job is to lead the way for the multinational force and help push the invading troops back to their own border.
