FM 3-24 (MCWP 3-33.5), ARMY FIELD MANUAL 3-24: COUNTERINSURGENCY (15 DEC 2006)., This field manual/Marine Corps warfighting publication establishes doctrine (fundamental principles) for military operations in a counterinsurgency (COIN) environment. It is based on lessons learned from previous counterinsurgencies
and contemporary operations. It is also based on existing interim doctrine and doctrine recently
developed. Counterinsurgency operations generally have been neglected in broader American military doctrine and national
security policies since the end of the Vietnam War over 30 years ago. This manual is designed to reverse
that trend. It is also designed to merge traditional approaches to COIN with the realities of a new international
arena shaped by technological advances, globalization, and the spread of extremist ideologies -- some of them
claiming the authority of a religious faith.
The manual begins with a description of insurgencies and counterinsurgencies. The first chapter includes a set
of principles and imperatives necessary for successful COIN operations. Chapter 2 discusses nonmilitary organizations
commonly involved in COIN operations and principles for integrating military and civilian activities.
Chapter 3 addresses aspects of intelligence specific to COIN operations. The next two chapters discuss the
design and execution of those operations. Developing host-nation security forces, an essential aspect of successful
COIN operations, is the subject of chapter 6. Leadership and ethical concerns are addressed in chapter
7. Chapter 8, which concerns sustainment of COIN operations, concludes the basic manual. The appendixes
contain useful supplemental information. Appendix A discusses factors to consider during the planning, preparation,
execution, and assessment of a COIN operation. Appendixes B and C contain supplemental intelligence
information. Appendix D addresses legal concerns. Appendix E describes the role of airpower.
