The world has descended into chaos but it isn't the undead that are the worst part. Panic, broken supply lines, disrupted communications, terrorized refugees, the friction and fog of war all combine to make hell on Earth. The battered men and women of America's storied First Infantry Division, based out of Fort Riley Kansas, are ordered to give up their fights in the cities and retreat towards to the National Redoubt in the Northwest. With ammunition, food and fuel running low and a soul searing death only a bite away, they start a retreat across the plains. In the way are armed gangs, undead hordes, incompetent leadership and a landscape irrevocably changed. The crew of Staff Sergeant Mark Matthews' Bradley Fighting Vehicle, BOHICA, run and gun, grinding undead in their tracks in a fighting retreat to the Pacific Northwest, one 25mm shell at a time. This is the follow up to Shane Gries' breakthrough best selling "The Thin Dead Line" and is set in the world of J.F. Holmes' "Irregular Scout Team One".
