Acknowledgments
The authors wish to thank the staff of the Under Secretary of Defense (Personnel
and Readiness) for their support, particularly Dan Gardner, Wayne Spruell, and
Mike Parmentier. We were helped throughout the course of this research project
by many other officers and civilians in the Defense, Air Force, and Navy
departments, and we owe them our thanks as well. A RAND colleague, Ron
Sortor, reviewed the drafts of all the publications from this research effort, and
we are grateful for his invaluable advice.
