ACKNOWLEDGMENTS Once again, we are especially grateful to Captain Richard O’Neill (U.S. Navy, now retired) at the Office of the Assistant Secretary of Defense/Command, Control, Communications, and Intelligence (OASD/C3I) for his interest, support, and guidance. We are also grateful for encouraging comments and other guidance from OASD/C3I personnel Captain Gregory Blackburn (U.S. Navy), Lieutenant Colonel Robert Walter (U.S. Army), and Commander Bob Scott (U.S. Navy). In addition, we are indebted to Dr. John Hamre (Deputy Secretary of Defense) for his insightful comments on an earlier version of this study. We are thankful to a number of members of the Highlands Forum, a consortium of government, business, academic, and media leaders devoted to the study of information-age issues, for the insightful comments they provided about some of the ideas we advance in this study. Finally, we benefited from thoughtful review comments provided by our RAND colleagues Robert Anderson and Greg Treverton and from skillful editing by Christina Pitcher. xiii
