When the U.S. military invaded Iraq, it lacked a common understanding of the problems inherent in counterinsurgency campaigns. It had neither studied them, nor developed doctrine and tactics to deal with them. It is fair to say that in 2003, most Army officers knew more about the U.S. Civil War than they did about counterinsurgency.
"The U.S. Army / Marine Corps Counterinsurgency Field Manual "was written to fill that void. The result of unprecedented collaboration among top U.S. military experts, scholars, and practitioners in the field, the manual espouses an approach to combat that emphasizes constant adaptation and learning, the importance of decentralized decision-making, the need to understand local politics and customs, and the key role of intelligence in winning the support of the population. The manual also emphasizes the paradoxical and often counterintuitive nature of counterinsurgency operations: sometimes the more you protect your forces, the less secure you are; sometimes the more force you use, the less effective it is; sometimes doing nothing is the best reaction.
An new introduction by Sarah Sewall, director of the Carr Center for Human Rights Policy at Harvard's Kennedy School of Government, places the manual in critical and historical perspective, explaining the significance and potential impact of this revolutionary challenge to conventional U.S. military doctrine.
An attempt by our military to redefine itself in the aftermath of 9/11 and the new world of international terrorism, "The U.S. Army / Marine Corps Counterinsurgency Field Manual "will play a vital role in American military campaigns for years to come.

"Soldiers represent what's best about the Army. Day in and day out, in the dark and in the mud and in faraway places, they execute tough missions whenever and wherever the Nation calls. They deserve our very best-leaders of character and competence who act to achieve excellence. That theme resounds throughout FM 22-100, Army Leadership, and echoes our time-honored principle of BE, KNOW, DO. This leadership manual lays out the framework that applies to all Army leaders-officer and NCO, military and civilian, active and reserve component. At the core of our leadership doctrine are the same Army Values embedded in our force: loyalty, duty, respect, selfless service, honor, integrity, and personal courage (LDRSHIP). The framework also outlines physical, mental, and emotional attributes that together with values form 'character'-what a leader must BE. Being a person of character is fundamental to the Army. What makes Army leaders of 'competence' are skills with people, ideas, things, and war-fighting. We refer to those four sets of skills as interpersonal, conceptual, technical, and tactical. Many are common to leaders in all situations; some additional skills are required for those who gain increasing responsibility. Leaders of character and competence are those with the appropriate skills, leaders who KNOW their people, their equipment, and their profession. All that is still not enough. We call on our leaders to translate character and competence into leader actions. Army Leaders influence people-by providing purpose, direction, and motivation-while operating to accomplish the mission and improving the organization. Leaders inspire others toward common goals and never lose sight of the future even as they labor tirelessly for the demands of today. That is what we expect our leaders to DO."-From the Preface.
