Serving one's country as a military man is rewarding experience. It is nevertheless a life of constraint. A military man serves within carefully prescribed limits, be it as enlisted man, junior officer, battalion commander, division commander, even senior field commander in time of war. The freedom to speak out in the manner of the private citizen, journalist, politician, legislator has no part in the assignment. Perhaps this is one reason why generals who have hung up their uniforms traditionally turn to the pen, seek an opportunity for free expression that they have long denied themselves, to report to the people they have served. In these pages I have tried to exercise that prerogative that in the end is mine, while at the same time seeking to make an objective and constructive contribution to the history of a dramatic era. In the idiom of the time, I have tried to tell it like it was. This is my personal story, yet inevitably it represents more than that; for my story is inextricably involved with the stories of those who served with me during thirty-six years in the United States Army- from wooden-wheeled artillery to antiballistic missile, from horse to spaceship, from volunteer army to draftee army in three wars and back to volunteer army. My story is particularly involved with the stories of those who served with such valor and sacrifice in the Republic of Vietnam. My hope is that in telling my story I have in some manner done justice to theirs, that I have to some degree contributed to an appreciation by the American people of arduous, imaginative, valiant service in spite of alien environment, hardship, restriction, frustration, misunderstanding, and vocal and demonstrative opposition.
