Field Manual (FM) 3-90-2 contributes to the Army and joint community by providing guidance on the conduct of reconnaissance, security, and other tactical enabling tasks. It provides guidance in the form of combat-tested tactics and procedures for tactical enabling tasks modified to exploit emerging Army and joint offensive and defensive capabilities. FM 3-90-2 expounds on the doctrinal fundamentals established in Army Doctrine Reference Publication (ADRP) 3-90. ADRP 3-90 and FM 3-90-1 must be read before reading FM 3-90-2, since that is where the doctrine and tactics for the conduct of offensive and defensive tasks and the art and science of tactics is found. FM 3-90-2 addresses the basic tactics associated with the conduct of tactical enabling tasks. The principal audience for FM 3-90-2 is all members of the profession of arms. Commanders and staffs of Army headquarters serving as a 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 publication. FM 3-90-2 focuses on the organization of forces, minimum essential control measures, and general planning, preparation, and execution considerations for each tactical enabling task not the subject of its own publication. It is the common reference for those tactical enabling tasks that it addresses for all students of the art and science of tactics, both in the field and the Army school system. The considerations in this publication apply to small tactical units, such as companies and battalions, even though most of the figures in this publication use the division and the brigade combat team (BCT) echelons to illustrate points in the text. Echelon-specific field manuals and Army techniques publications address the specifics of how each tactical echelon conducts these tactical enabling tasks. FM 3-90-2 implements standardization agreement (STANAG) Allied Tactical Publication-3.2.1. 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. (See FM 27-10.) FM 3-90-2 uses joint terms where applicable. Selected joint and Army terms and definitions appear in both the glossary and the text. Terms for which FM 3-90-2 is the proponent publication (the authority) are marked with an asterisk (*) in the glossary.

This publication, Field Manual FM 3-98 Reconnaissance and Security Operations July 2015, provides doctrinal guidance and direction for Cavalry organizations, as well as reconnaissance and security organizations. This FM establishes the foundation for the development of tactics and procedures in subordinate doctrine publications. This publication applies across the range of military operations. While the main focus of this field manual is Cavalry formations within the units listed below, all maneuver formations must be able to conduct reconnaissance and security tasks. - Armored brigade combat team (ABCT) Cavalry squadron. - Infantry brigade combat team (IBCT) Cavalry squadron. - Stryker brigade combat team (SBCT) Cavalry squadron. - Battlefield surveillance brigade (BFSB) Cavalry squadron. - It is applicable to the- - Scout platoon of maneuver battalions. - Combat aviation brigade air squadron. The principal audiences for FM 3-98 are commanders, leaders, and staffs responsible for the planning, execution, or support of reconnaissance and security operations as well as instructors charged with teaching reconnaissance and security operations. Doctrine consists of fundamental principles that describe how to fight. At the tactical level, doctrine consists of authoritative principles concerning how to execute reconnaissance and security operations as part of Army and joint operations that require professional military judgment in their application. Importantly, our doctrine must describe how brigade combat teams (BCT) and subordinate units combine the capabilities of various arms into cohesive, combined arms, air-ground teams and provide a clear description of how to execute reconnaissance and security operations. This publication provides the commander and staff of Cavalry formations with doctrine relevant to Army and joint operations. This publication explains how effective reconnaissance and security operations generate depth, allow commanders reaction time and maneuver space, fight for information and collect information through stealth, protect against surprise, ease the forward movement of follow-on forces, and provide commanders with flexibility and adaptability. The doctrine described in this publication is applicable across unified land operations. The previous proponent manual for Cavalry Operations was FM 3-20.96, published 12 March 2010, which included operational considerations. This publication provides doctrinal guidance for all formations assigned to the ABCT, the IBCT, and SBCT. The following is a summary of each chapter in the manual: Chapter 1 addresses the role of Cavalry in unified land operations and Cavalry organizations. Chapter 2 discusses understanding the threat, potential threat groups and threat characteristics. Chapter 3 addresses the operational environment, shaping, engaging, and influencing outcomes, and consolidating gains. Chapter 4 highlights the updated concepts of mission command in relation to commander's reconnaissance and security guidance, the operations process and information collection. Chapter 5 begins with an overview, followed by a detailed discussion of the fundamentals of reconnaissance, forms of reconnaissance, and reconnaissance handover. Chapter 6 begins with an overview, followed with the fundamentals of security operations, counterreconnaissance, and the forms of security. Chapter 7 provides a short overview and then devotes a section to reconnaissance and security stability planning, stability principles and frameworks, and stability tasks. Chapter 8 describes sustainment for reconnaissance and security tasks, sustainment planning considerations for reconnaissance and security, sustainment considerations for reconnaissance and security and special sustainment consideration.

The official United States Army manual, U.S. Army Reconnaissance and Surveillance Handbook provides tactics, techniques, and procedures for reconnaissance and surveillance planning, mission management, and reporting. Throughout history, military leaders have recognized the importance of reconnaissance and surveillance. Gaining and maintaining contact with the enemy is essential to win the battle, and U.S. military history contains many examples where our knowledge of the enemy, or lack of knowledge, directly led to victory or defeat. The role of reconnaissance and surveillance has not diminished on the modern battlefield; if anything, it has become even more important. Battles at the combat training centers prove that a good reconnaissance and surveillance effort is critical to successful attacks. On the other hand, a poor reconnaissance and surveillance effort almost guarantees defeat for the commander. The message is clear: success on the battlefield begins with reconnaissance and surveillance. This essential handbook covers: Surveillance Preparation Assets Equipment Planning Monitoring Organizing Missions Electronic warfare Counter-reconnaissance And more! It also looks at the development of intelligence, employment considerations for reconnaissance, and defines the roles of various personnel in planning operations. Intended for maneuver commanders and their staffs; intelligence staffs and collection managers; and other personnel involved in planning and reconnaissance and counter-reconnaissance operations, and now available to everyone, U.S. Army Reconnaissance and Surveillance Handbook provides an insider’s look into the world of Army intelligence.

This field manual establishes doctrine 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 40 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. This is a comprehensive manual that details every aspect of a successful COIN operation from intelligence to leadership to diplomacy. It also includes several useful appendices that provide important supplementary material.
