Ten field-manual principles proven in combat
Everyone wants to win. Even when defeat is framed as a paradoxical step toward success, the drive to come out on top is constant. Nam Boram, a military historian and senior researcher at the Ministry of Defense’s Military History Research Institute, lays out core doctrines for victory in his new book Winnership. Built on the U.S. Army field manual on leadership, the book distills ten principles that have been validated in combat.
The book presents foundational concepts — Read minds; Lead by example; Learn proactively; Anticipate scenarios; Face reality; Share information; Develop subordinates’ capabilities; Be candid; Delegate; Verify and supervise — and pairs each with case studies of commanders who proved their leadership on the battlefield.
Boram treats leadership not as an abstract virtue but as a set of practical, testable principles that must hold up under competition and crisis. Drawing on the U.S. Army manual and military history, he argues that organizations survive and earn lasting recognition only when leaders make decisions and set standards that secure victory.
He stresses that leaders must remain resilient under pressure, coolly diagnose the causes of defeat, and be prepared to recover. The book’s central thesis is that leadership is not a collection of good-sounding words but a series of actions that determine success or failure.
The narrative is enlivened with a broad range of sources — lessons from military history, leadership books and lectures, and survey data — which help illustrate the points and keep the reader engaged.
Boram also flags common pitfalls for each principle, outlines the consequences of poor leadership, and provides practical methods to overcome those failures. True to his training as a military historian, he draws on the thinking and behavior of victors such as George Marshall, Dwight D. Eisenhower, Robert McNamara, Hamilton Howze, and Henry Stimson to help readers extract their own lessons about winning.
In his closing chapter, he examines how leaders on the front lines of venture firms and startups have prevailed in brutal competition. He emphasizes that winners treated every place they stood as their arena and that what you need to become a winner is often right beside you — the key is to recognize it and act.
Winnership is not merely a manual about winning wars. The conflicts and commanders it examines serve as prompts for individuals and organizations seeking to prevail in competition. The principles the book offers should become essential traits for leaders who must overcome future crises and secure victory.
Centered on ten principles, the book lays out standards applicable to military units, businesses, and civilian organizations alike. Through clear case studies, it shows the failures that follow from poor leadership and, conversely, the mindsets and actions that enabled winners to lead their organizations to success. The tone is direct and resolute, but that clarity forces readers to reassess an organization’s goals, crisis response, and decision-making. As a practical leadership guide, it points a clear way forward for readers who want to know what makes a winning leader rather than merely a good one.
