Query: A true Marine officer.

The title of this review is the highest compliment an officer can receive from another Marine. I would have been proud to have served with Lieutnant Kirschke in Vietnam. We were there at the same time, but in different units. This book is the truth. This book is written by a man who walked the walk. This book should be required reading at the Naval Academy, at Marine Corps OCS, and the Basic School at Quantico. The success of an officer in the Corps depends on whether he accomplishes the mission and that his men respect him while doing it. Mister Kirschke not only did the job, but won the love and respect of his Marines. Semper Fidelis, sir!
