To Deanie, who's been there every step of the way. - Martin Dempsey

There are people in our lives who may know more about what's good for us than we do.

Ranger School is the toughest training offered in the Army- not a place for the faint of heart and only recently open to women. Only a fraction of the soldiers who enter the nine-week course make it out successfully.

There was a certain comfort in returning to West Point after a month at home- not because I was back among those who universally supported the war, but quite the opposite: I was back among those who believed the Vietnam War would soon be theirs to wage and wanted earnestly to understand it. I was back among classmates and instructors who encouraged me to challenge both the idea that the war was a lost cause and the notion that it should not be questioned simply because it was the policy of the U.S. government. I was back in an institution that provided and promoted a liberal education as essential in the preparation for becoming a military officer. I didn't know it at the time, but those days were just the beginning of a journey in learning how to listen, to learn, to question, to communicate, to apply knowledge and skills to real-world problems honestly and with an open mind. Later, long after I had graduated from West Point, I would make sure those around me knew that I would always welcome, even expect, a bit of sensible skepticism.
