As with Admiral Winnefeld’s last book, Career Compass, this work gives naval officers the information they need to build a successful career. It covers the entire career spectrum, complementing and supplementing his previous work, as it addresses such topics as the importance and challenges of joint tours, and relations with chiefs and other enlisted sailors. Taking a chronological approach, the author offers advice appropriate to all levels. Chapters on mid-grade tours are particularly useful because they are not covered in other volumes in the series. Professional Navy Officer breaks new ground while reinforcing the best advice given over the years to those seeking a successful career as a naval officer. Rear Admiral James A. Winnefeld Sr., USN (Ret.), is a graduate of the Naval Academy, and has held multiple commands at sea, in both aviation and surface units. He lives in Annapolis, USA.
