As with most things in my life, this book would have not been possible if it were not for many people. I want to thank Sharon Young and David Dusthimer from Pearson for giving me the opportunity to develop a book on such an important topic. Their guidance and support were invaluable. I am grateful to my wife, Lori, for her unwavering support and love. My professional mentors, Drs. Bruce Crow and Dennis Grill, have made it possible for me to understand the military culture as well as I do; for this I am indebted to them. And last, I am grateful to the men and women in uniform and their families for the countless sacrifices they have made and continue to make for me and my loved ones.
