What makes this book more interesting is that apart from description on the tactics and naval operation at sea, it also discusses various subjects that we might have forgotten for a long time in executing the management in dealing with the battle, such as the importance of team work cooperation and firmed and clear command, moral strength, discipline, leadership ethics and also quality of a certain decision as well as its momentum. Through this book, the writer has reminded and revitalized some important subjects that may not be neglected in battle management.

Analysis and review on Sun Tzu's teaching in this book has direct context with the historical events of sea wars during this 20th century, namely the Pacific War (1941-1945) and Falklands War (1982). In Pacific War, it was proven that Sun Tzu strategy was effective at the sea battle at the Pacific Ocean, while in 1980s it was also effective as the biggest British maritime campaign strategy since the World War II. Those two sea battles have the principles and operations as taught by Sun Tzu for the field operation at the sea. (Preface by Aristides Katoppo, Chairperson at Sinar Harapan, Indonesia Newspapers ).
