Army forces are the decisive component of land warfare in joint and multinational operations. Army forces aggressively gain the initiative, build and maintain momentum, and exploit success to control the nature, scope, and tempo of full spectrum operations in war and military operations other than war. Execution of this doctrine requires well-trained soldiers and units fueled with the warrior ethos, the best weapons and equipment available, and the solid leadership of officers and noncommissioned officers of character and competence.


FM 3-0 establishes the Army's keystone doctrine for full spectrum operations. The doctrine holds warfighting as the Army's primary focus and recognizes that the ability of Army forces to dominate land warfare also provides the ability to dominate any situation in military operations other than war. The foundation of FM 3-0 is built upon global strategic responsiveness for prompt, sustained Army force operations on land as a member of a joint or multinational force.

FM 3-0 is compatible with joint doctrine. It provides overarching doctrinal direction for the conduct of full spectrum operations detailed in other Army manuals. As the Army's principal tool for professional education in the art and the science of war, FM 3-0 presents a stable body of operational doctrine rooted in actual military experience. FM 3-0 provides a foundation for the development of tactics, techniques, and procedures.


FM 3-0 is divided into four parts. Part One (Chapters 1-3) discusses the Army's role in peace, conflict, and war. Part Two (Chapters 4-6) discusses the fundamentals of full spectrum operations, battle command, and the operations process. Part Three (Chapters 7-10) discusses the four types of Army operations: offensive, defensive, stability, and support. Part Four (Chapters 11 and 12) discusses information superiority and combat service support as enabling operations.


FM 3-0 provides operational guidance for commanders and trainers at all echelons and forms the foundation for curricula within the Army Education System. Its audience is broad, from battalion through corps to other operational-level organizations. Officers and senior noncommissioned officers must read and understand FM 3-0.

Cross-references use the new field manual numbering system. The bibliography lists field manuals by new number followed by old number.

The glossary lists most terms used in FM 3-0 that have joint or Army definitions. Terms for which FM 3-0 is the proponent manual (the authority) are indicated with an asterisk. The glossary does not contain these definitions, but lists the numbers of paragraphs where terms are defined. Definitions for which FM 3-0 is the proponent manual are printed in boldface in the text. Other definitions are not printed in boldface. Partial definitions of some terms for which FM 3-0 is not the proponent manual are provided in text boxes. See JP 1-02 for complete joint definitions and FM 1-02 for complete Army definitions.

The glossary contains referents of acronyms and definitions of terms not defined in JP 1-02 and FM 1-02. It does not list acronyms and abbreviations that are included for clarity only and appear one time, nor those that appear only in a figure and are listed in the legend for that figure. Some common abbreviations and acronyms-for example, the abbreviations for military ranks and publications-are not spelled out; refer to the glossary. Since ARFOR is a defined term as well as an acronym, it is not spelled out.

Some figures show engagement areas and objectives without names. These control measures are normally given names (see FM 1-02).
