A blizzard is the perfect cover for a shocking act of Russian aggression. Emboldened by their successful annexation of the Crimea, a power-mad Russian president sends his troops over the border into eastern Germany. Standing against them are the woefully undermanned American forces. Army Staff Sergeant George O'Neill is the man tasked with making information flow again and getting the Americans back into the game. But it's up to hundreds of individual American soldiers and airmen to hold back the flood of Russian troops in order to buy O'Neill the time he needs to bring out the big guns.
