Studying The Conduct of War: “We Surely Must Do Better”

Chris and I both have discussed previously the apparent waning interest on the part of the Department of Defense to sponsor empirical research studying the basic phenomena of modern warfare. The U.S. government’s boom-or-bust approach to this is long standing, extending back at least to the Vietnam War. Recent criticism of the Department of Defense’s Office of Net Assessment (OSD/NA) is unlikely to help. Established in 1973 and led by the legendary Andrew “Yoda” Marshall until 2015, OSD/NA plays an important role in funding basic research on topics of crucial importance to the art of net assessment. Critics of the office appear to be unaware of just how thin the actual base of empirical knowledge is on the conduct of war. Marshall understood that the net result of a net assessment based mostly on guesswork was likely to be useless, or worse, misleadingly wrong.

This lack of attention to the actual conduct of war extends beyond government sponsored research. In 2004, Stephen Biddle, a professor of political science at George Washington University and a well-regarded defense and foreign policy analyst, published Military Power: Explaining Victory and Defeat in Modern Battle. The book focused on a very basic question: what causes victory and defeat in battle? Using a comparative approach that incorporated quantitative and qualitative methods, he effectively argued that success in contemporary combat was due to the mastery of what he called the “modern system.” (I won’t go into detail here, but I heartily recommend the book to anyone interested in the topic.)

Military Power was critically acclaimed and received multiple awards from academic, foreign policy, military, operations research, and strategic studies organizations. For all the accolades, however, Biddle was quite aware just how neglected the study of war has become in U.S. academic and professional communities. He concluded the book with a very straightforward assessment:

[F]or at least a generation, the study of war’s conduct has fallen between the stools of the institutional structure of modern academia and government. Political scientists often treat war itself as outside their subject matter; while its causes are seen as political and hence legitimate subjects of study, its conduct and outcomes are more often excluded. Since the 1970s, historians have turned away from the conduct of operations to focus on war’s effects on social, economic, and political structures. Military officers have deep subject matter knowledge but are rarely trained as theoreticians and have pressing operational demands on their professional attention. Policy analysts and operations researchers focus so tightly on short-deadline decision analysis (should the government buy the F22 or cancel it? Should the Army have 10 divisions or 8?) that underlying issues of cause and effect are often overlooked—even when the decisions under analysis turn on embedded assumptions about the causes of military outcomes. Operations research has also gradually lost much of its original empirical focus; modeling is now a chiefly deductive undertaking, with little systematic effort to test deductive claims against real world evidence. Over forty years ago, Thomas Schelling and Bernard Brodie argued that without an academic discipline of military science, the study of the conduct of war had languished; the passage of time has done little to overturn their assessment. Yet the subject is simply too important to treat by proxy and assumption on the margins of other questions In the absence of an institutional home for the study of warfare, it is all the more essential that analysts in existing disciplines recognize its importance and take up the business of investigating capability and its causes directly and rigorously. Few subjects are more important—or less studied by theoretical social scientists. With so much at stake, we surely must do better. [pp. 207-208]

Biddle published Military Power 12 years ago, in 2004. Has anything changed substantially? Have we done better?
