Hunter Ripley "Rip" Rawlings III is a New York Times Best Selling Author, and served in the United States Marine Corps (23 Years) as an Infantry & LAR Reconnaissance Officer. His new book, "The Kill Box", is a great sequel to his debut novel "Assault by Fire", based on a Russian invasion of the United States and the resistance by an out-manned and out-supplied American force in the hills of West Virginia. It's a LOT of fun.
