Army Doctrine Reference Publication (ADRP) 3-0, Unified Land Operations, is the first ADRP released under Doctrine 2015. ADRP 3-0 expands on the foundations and tenets found in Army Doctrine Publication (ADP) 3-0. This ADRP expands on the doctrine of unified land operations found in ADP 3-0. The publication of ADP 3-0 shifted the Army's operational concept from full spectrum operations to unified land operations. The doctrine of unified land operations describes how the Army demonstrates its core competencies of combined arm maneuver and wide area security through decisive action. The term decisive action replaces the term full spectrum operations as the concept of continuous, simultaneous offense, defense, stability, or defense support of civil authorities. Defense support of civil authorities replaces civil support as a task under decisive action. ADRP 3-0 expands the discussion of the foundations and tenets of unified land operations, as well as the operational framework found in ADP 3-0. Additional changes in ADRP 3-0 from the now obsolete 2011 FM 3-0, Change 1, includes a discussion of the range of military operations replacing the spectrum of conflict as well as a discussion of information collection replacing intelligence, reconnaissance, and surveillance (known as ISR). These changes in ADRP 3-0 now better align Army doctrine with the joint discussion of the principles of joint operations. ADRP 3-0 remains generally consistent with the now obsolete 2011 FM 3-0, Change 1, on key topics while adopting updated terminology and concepts as necessary. These topics include the discussion of an operational environment and the operational and mission variables, as well as the discussions of unified action, law of land warfare, and combat power. As in the now obsolete 2011, FM 3-0, Change 1, mission command remains both a philosophy of command and a warfighting function. Finally, ADRP 3-0 maintains combined arms as the application of arms that multiplies Army forces' effectiveness in all operations. ADRP 3-0 contains four chapters: Chapter 1 shortens the discussion of the operational environment found on the now obsolete 2011 FM 3-0, Change 1, and emphasizes military operations. This chapter provides a framework of variables of an operational environment that shape their nature and affect outcomes. The chapter then discusses unified action and joint operations as well as land operations. Finally, this chapter discusses law of land warfare and combined arms. Chapter 2 introduces the Army's new operational concept of unified land operations. It discusses how commanders apply landpower as part of unified action to defeat the enemy on land and establish conditions that achieve the joint force commander's end state. Chapter 2 discusses how commanders demonstrate the Army's new core competencies of combined arms maneuver and wide area security conducted through decisive action. Chapter 3 discusses combat power and the warfighting functions used to generate combat power in support of unified land operations. As in the now obsolete 2011 FM 3-0, Change 1, chapter 3 discusses the eight elements of combat power that include the six warfighting functions with leadership and information. Lastly, it discusses how Army forces achieve combined arms through force tailoring, task organization, and mutual support. Chapter 4 discusses the elements of operational art and the meaning of operational art to Army forces. It elaborates on commanders and staffs applying the elements of operational art to understand, visualize, and describe how to establish conditions to achieve a desired end state. It discusses how operational art represents a creative approach to dealing with the direction of military forces and expresses an informed vision across the levels of war.

ADP 3-0, Operations, constitutes the Army's view of how to conduct prompt and sustained operations across multiple domains, and it sets the foundation for developing other principles, tactics, techniques, and procedures detailed in subordinate doctrine publications. It articulates the Army's operational doctrine for unified land operations. ADP 3-0 accounts for the uncertainty of operations and recognizes that a military operation is a human undertaking. Additionally, this publication is the foundation for training and Army education system curricula related to unified land operations. The principal audience for ADP 3-0 is all members of the profession of arms. Commanders and staffs of Army headquarters serving as joint task force (JTF) or multinational headquarters should also refer to applicable joint or multinational doctrine concerning the range of military operations and joint or multinational forces. Trainers and educators throughout the Army will use this publication as well.

Army unified land operations doctrine expands the discussion of overarching guidance on the Army's core competencies of combined arms manuever and wide area security

The U.S. military does not believe its soldiers, sailors, airmen, and marines should be engaged in combat with adversaries on a "level playing field." Our combat individuals enter engagements to win. To that end, the United States has used its technical prowess and industrial capability to develop decisive weapons that overmatch those of potential enemies. In its current engagement-what has been identified as an "era of persistent conflict"- the nation's most important weapon is the dismounted soldier operating in small units. Today's soldier must be prepared to contend with both regular and irregular adversaries. Results in Iraq and Afghanistan show that, while the U.S. soldier is a formidable fighter, the contemporary suite of equipment and support does not afford the same high degree of overmatch capability exhibited by large weapons platforms-yet it is the soldier who ultimately will play the decisive role in restoring stability. Making the Soldier Decisive on Future Battlefields establishes the technical requirements for overmatch capability for dismounted soldiers operating individually or in small units. It prescribes technological and organizational capabilities needed to make the dismounted soldier a decisive weapon in a changing, uncertain, and complex future environment and provides the Army with 15 recommendations on how to focus its efforts to enable the soldier and tactical small unit (TSU) to achieve overmatch.

Doctrine provides a military organization with unity of effort and a common philosophy, language, and purpose. This manual, "Theater Army Operations" (FM3-93), discusses the organization and operations of the theater army headquarters, including its role as the Army Service component command (ASCC) to the geographic combatant commander (GCC) and the relationships between the theater army headquarters and the theater enabling commands. The manual also discusses theater army responsibilities for setting the theater, Title 10 functions and responsibilities, generally referred to as the combatant commander's daily operations requirements, as well as the operational employment of the theater army's contingency command post (CCP) to directly mission command limited types of operations.

Army Doctrine Publication (ADP) 6-0 presents the Army's guidance on command, control, and the mission command warfighting function. This publication concisely describes how commanders, supported by their staffs, combine the art of command and the science of control to understand situations, make decisions, direct action, and accomplish missions. The principal audience for ADP 6-0 is all professionals within the Army. Commanders and staffs of Army headquarters serving as joint task force or multinational headquarters should also refer to applicable joint or multinational doctrine on command and control of joint or multinational forces. Trainers and educators throughout the Army will also use this publication. Commanders, staffs, and subordinates ensure their decisions and actions comply with applicable U.S., international, and, in some cases, host-nation laws and regulations. Commanders at all levels ensure their Soldiers operate in accordance with the law of war and the rules of engagement. ADP 6-0 applies to the Active Army, Army National Guard/Army National Guard of the United States, and United States Army Reserve unless otherwise stated.

When we published Change 1 to the 2008 edition of (Field Manual) FM 3-0, we captured the most critical lessons of almost ten years of sustained land combat. In this edition, we not only reflect on the past but also look to an uncertain future. Army Doctrine Publication (ADP) 3-0, Unified Land Operations, provides a common operational concept for a future in which Army forces must be prepared to operate across the range of military operations, integrating their actions with joint, interagency, and multinational partners as part of a larger effort. Unified Land Operations is a natural intellectual outgrowth of past capstone doctrine. AirLand battle recognized the three dimensional nature of modern warfare, while full spectrum operations recognized the need to conduct a fluid mix of offensive, defensive, and stability operations simultaneously. This publication builds on both these ideas, adding that success requires fully integrating Army operations with the efforts of joint, interagency, and multinational partners. The central idea of Unified Land Operations is that Army units seize, retain, and exploit the initiative to gain and maintain a position of relative advantage in sustained land operations to create conditions for favorable conflict resolution. This central idea applies to all military operations-offensive, defensive, and stability or defense support of civil authorities. This unifying principle connects the various tasks Army forces may perform. It adds the founding principles of flexibility, integration, lethality, adaptability, depth, and synchronization. It incorporates the principle that operational art is the connection between strategic objectives and tactical actions, and provides a common construct for organizing military operations. The construct consists of the Army operations process, an operations framework for visualizing and describing operations, and the warfighting functions. ADP 3-0 serves as the common operational concept for the Army. The central idea, adapted to the unique conditions of each conflict, represents the Army's unique contribution to unified action. It must permeate our doctrine, our training, and our leader professional development programs.
