This book is a partial reprint of U.S. Army manual FM 3-90, July 2001.

Tactics is the art and science of employing all available means to win battles and engagements. Specifically, it comprises the actions taken by a commander to arrange units and activities in relation to each other and the enemy. Filled with diagrams of attack plans, defensive strategies, and troop movements, U.S. Army Tactics Field Manual is the playbook the U.S. Army uses to employ available means to win in combat. This book provides combat-tested concepts and ideas modified to exploit emerging Army and joint capabilities. This book focuses on the organization of forces, minimum essential control measures, and general planning, preparation, and execution considerations for each type and form of combat operation. It is the common reference for all students of the tactical art, both in the field and the Army school system. The Art of Tactics * Common Tactical Concepts and Graphic Control Measures * The Basics of Offense * Movement to Contact * Attack * Exploitation * Pursuit * Basics of Defensive Operations * The Area of Defense * The Mobile Defense * The Retrograde * Security Operations * Reconnaissance Operations * Troop Movement * Relief in Place * Passage of Lines.

This paper focuses on the formulation of doctrine since World War II. In no comparable period in history have the dimensions of the battlefield been so altered by rapid technological changes. The need for the tactical doctrines of the Army to remain correspondingly abreast of these changes is thus more pressing than ever before. Future conflicts are not likely to develop in the leisurely fashions of the past where tactical doctrines could be refined on the battlefield itself. It is, therefore, imperative that we apprehend future problems with as much accuracy as possible. One means of doing so is to pay particular attention to the business of how the Army's doctrine has developed historically, with a view to improving methods of future development.

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.

What does it take to lead an army in battle? What does it take to win? Competent leaders of character are essential for the Army to meet the challenges in the dangerous and complex security environment we face today. The U.S. Army Leadership Handbook (FM 6-22) is the Army’s flagship field manual on leadership. It establishes leadership doctrine and fundamental principles for all officers, noncommissioned officers, and Army civilians across all components using the “BE-KNOW-DO” concept. It is critical that Army leaders be agile, multiskilled athletes who have strong moral character, broad knowledge, and keen intellect. Leaders—military and civilian alike—must set the example, teach, and mentor, and this manual provides the principles, concepts, and training to accomplish this important task. Filled with leadership principles crucial to the U.S. military and equally applicable to leaders in any walk of life, this up-to-date manual from the Army will teach all leaders everything they need to know.

This field manual establishes doctrine (fundamental principles) for tactical counterinsurgency (COIN) operations at the company, battalion, and brigade level. It is based on lessons learned from historic counterinsurgencies and current operations. This manual continues the efforts of FM 3-24, Counterinsurgency, in combining the historic approaches to COIN with the realities of today's operational environment (OE)-an environment modified by a population explosion, urbanization, globalization, technology, the spread of religious fundamentalism, resource demand, climate change and natural disasters, and proliferation of weapons of mass destruction. This manual is generic in its geographic focus and should be used with other doctrinal sources.

Army Tactics, Techniques, and Procedures (ATTP) 3-39.32 provides doctrinal guidance for personnel who are responsible for planning and executing physical security programs. It is the basic reference for training security personnel and is intended to be used in conjunction with the Army Regulation (AR) 190 series (Military Police), Security Engineering Unified Facilities Criteria (UFC) publications, Department of Defense (DOD) directives, and other Department of the Army (DA) publications. This publication applies to the Active Army, the Army National Guard (ARNG)/Army National Guard of the United States (ARNGUS), and the United States Army Reserves (USAR) unless otherwise stated. Prevention and protection are the two primary concerns of physical security; both serve the security interests of people, equipment, and property. This ATTP establishes physical security as a supporting component of the protection warfighting function and describes defensive measures that enable protection tasks, such asoperations security, antiterrorism, operational area security, survivability, and information protection.
