From the persective of a U.S. Army Officer, I highly recommend this book. Mr. Hoiback does an excellent job, in a very concise manner, to describe the linkage between Authority, Intent, and Dissemination of command. He then uses two case studies that show the relationships in the real world.I really appriciated the second case study showing the opening days of WWII in Norway. The case study told the story of COL Erickson who took the initiative to sink a German Cruiser amid the cowardice of the politicians and the inadequate preparations to maintain Norway's neutrality; a story I never read before this book. I would recommend reading the second case study before the first case study discussing the GEN Haig in the First World War. By reading the Second Case study first, I believe that case study one will be easier to follow.Eric
