Good representation of a subject which is already documented in the literature by many sources. Me in this book the undemanding use too familiar photo material Regardless of the Osprey typical clear presentation of the subject, and elaborate illustrations anschaulichem maps noticed. There are - since cancellation of "classified material" -very many interesting photographs of the US Navy-Rapporteur are now available and have only limited application found here. Too bad, because this material newly available differs latest writings of the books of the 80's and 90's on the subject. Therefore, a point deduction. Apart from still the book is recommended!
