The United States Marine Corps has a unique culture that ensures comradery, exacting standards, and readiness to be the first to every fight. Yet even in a group that is known for innovation, culture can push leaders to fall back on ingrained preferences. In her new book “The Marines, Counterinsurgency, and Strategic Culture: Lessons Learned and Lost in America's Wars,” USU Associate Professor of Political Science Jeannie L. Johnson takes a sympathetic but critical look at the Marine Corps's long experience with counterinsurgency warfare. Which counterinsurgency lessons have been learned and retained for next time and which have been abandoned to history is a story of battlefield trial and error―but also a story of cultural collisions.
