This publication, Field Manual FM 1-0 Human Resources Support April 2014, provides the fundamentals, principles, and concepts of Army human resources (HR) support doctrine. It provides the doctrinal bases for developing operational plans (OPLANS) and standard operating procedures (SOPs) that support national objectives that reinforce the Army's vision that Soldiers and readiness are the principle focus of HR support. This publication applies to the range of military operations and supports Army doctrine publication (ADP) 3-0, Unified Land Operations and ADP 4-0, Sustainment. The principle audience for FM 1-0 is all members of the profession of arms. Commanders and staffs of Army headquarters serving as joint task force 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 also use this manual. Field manual (FM) 1-0, Human Resources Support, is the second revision of this publication. FM 1-0 provides human resources professionals and commanders an understanding of how human resources support contributes to current and future operations and how human resources professionals, organizations, and systems play an increasingly critical role in support of the total force. This manual provides basic doctrinal discussion on the organization and operations of human resources entities within the Army, as well as standard requirements code (SRC) -12, Adjutant General Corps, organizations.

This chapter provides recommendations for home station employment of the aforementioned organizations, while also discussing HR rear detachment responsibilities previously addressed in appendix A. Chapter 3 through 6 discuss the four HR core competencies of man the force, provide HR services, coordinate personnel support, and conduct HR planning and operations. A section covering HR automations support is now included in chapter 3, detailing the many HR enabling systems.
