Facing added scrutiny in the wake of his predecessor’s resignation, new National Security Council chief of staff H.R. McMaster will have to learn from Michael Flynn’s mistakes. Fortunately learning is one of his favorite hobbies.

In 2012, while commander of the US Army Maneuver Center of Excellence at Fort Benning, Georgia, McMaster did an interview with the management consulting firm McKinsey in which he talked about the evolution of the army, as well as “what competencies our leaders need and…how, where, and at what point in their careers we train and educate them.” One of those strategies, McMaster said, was “to cultivate within our leaders a desire for lifelong learning and to provide them with the tools necessary for informal self-study and collaborative study across their careers.”

To that end, McMaster—a scholar of military history—provided a list of books any professional involved in military affairs should read, covering everything from ancient warfare to modern innovation. Now he’ll just have to convince US president Donald Trump to pick one up.

Here’s the full list (all text below is McMaster’s). It originally appeared here (sidebar a little over halfway down, on the left-hand side of the interview text).

General grounding

There are several essential reads for professionals involved in military affairs:

Carl von Clausewitz—On War

The author uses a dialectical approach to understanding war without being prescriptive.

Michael Howard—War in European History

This book is excellent, as is anything by this author.

Elting Morison—Men, Machines, and Modern Times

The author discusses the limitations of emerging technologies—specifically, he argues that instead of taming our environment, technology has further complicated it.

Williamson Murray—The Making of Strategy: Rulers, States, and War

This book helps connect military action to strategy.

Thucydides—The History of the Peloponnesian War

The Greek historian shows that the drivers of war—fear, honor, self-interest—haven’t changed over time.

Innovation and the world wars

Much has been written about World War I, World War II, and the interwar period—and about how these events changed the nature of war. The following are favorites:

Marc Bloch—Strange Defeat

Robert A. Doughty—The Breaking Point: Sedan and the Fall of France, 1940, and Pyrrhic Victory: French Strategy and Operations in the Great War

Timothy T. Lupfer—Dynamics of Doctrine: The Changes in German Tactical Doctrine During the First World War

Williamson Murray—Military Innovation in the Interwar Period

Memoirs and biographies

It is important to understand how leaders have adapted and thought about war and warfare across their careers. The Autobiography of General Ulysses S. Grant: Memoirs of the Civil War is perhaps the best war memoir ever written. The following are some other significant titles:

Carlo D’Este—Patton: A Genius for War

David Fraser—Knight’s Cross: A Life of Field Marshal Erwin Rommel

Matthew B. Ridgway—The Korean War
