Leading Marines describes the leadership philosophy that distinguishes the U.S. Marine Corps. This publication is not meant to be a “how to” guide on leadership, rather, it provides broad guidance in the form of concepts and values. Leading Marines is meant to be read from cover to cover and its three chapters have a natural progression. Chapter 1 describes our ethos—who we are and what we do for our Nation. Building on that understanding, Chapter 2 covers the foundations of Marine Corps leadership and Chapter 3 addresses overcoming leadership challenges.
