This United States Army field manual, Army Techniques Publication ATP 3-34.22 Engineer Operations - Brigade Combat Team and Below April 2021, provides a doctrinal foundation for the conduct of engineer operations in support of unified land operations, focused on tactical maneuvers at the brigade combat team (BCT) level and below. The engineer organizations organic to the BCT are optimized to perform combat engineering tasks (primarily mobility with limited capabilities in countermobility and survivability), with geospatial engineering teamsproviding organic capability. Additional engineering support (combat and general) comes from engineer organizations that are task-organized to the BCT or that provide support from echelons above brigade (EAB) organizations. This manual is aligned with current BCT doctrine (see FM 3-96) and describes engineer support for the armored brigade combat team (ABCT), infantry brigade combat team (IBCT), and Stryker brigade combat team (SBCT). Although the security force assistance BCT and its respective engineer battalions are not addressed in detail, the basic principles of this manual also apply to those organizations. The principal audience for ATP 3-34.22 consists of commanders, officers, noncommissioned officers (NCOs), and staff at the BCT level and below as well as EAB units that support BCTs. ATP 3-34.22 is a primary manual for instructional purposes within the United States Army Engineer School and assists other Army branch schools in teaching the integration of engineer capabilities into Army operations. ATP 3-34.22 applies to the Active Army, Army National Guard/Army National Guard of the United States and United States Army Reserve unless otherwise stated.
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.
This manual, Army Techniques Publication ATP 3-34.22 ENGINEER OPERATIONS-BRIGADE COMBAT TEAM AND BELOW December 2014, provides a doctrinal foundation for the conduct of engineer operations in support of unified land operations that are focused on tactical maneuvers at the brigade combat team (BCT) level and below. The engineer support doctrine for the BCT is focused on tactical-level maneuvers. The engineer organizations that are organic to the BCT are optimized to perform combat engineering tasks (primarily mobility with limited capabilities in countermobility and survivability). Geospatial engineering support is provided by organic terrain teams. Additional engineering support (combat and general) comes from engineer organizations that are task-organized to the BCT or that provide support from echelons above brigade (EAB) organizations. This manual is aligned with current BCT doctrine and describes engineer support for the armored BCT, infantry BCT, and Stryker BCT. (See FM 3-90.6.) Although the armored cavalry regiment and engineer company are not specifically addressed, the basic principles of this manual also apply to those organizations.
Fought over the course of four years, the Civil War pitted countrymen against countrymen, North versus South, friend against friend, and brother against brother. The photographs within these pages document the war that united America as one. These rare shots were taken in the middle of the battlefield during the earliest days of photography. Selected from a collection of seven thousand original negatives, these historic photos capture nearly every aspect of Civil War life. Among these photos are images of camps sprawling across acres, soldiers at their battlements, firing of heavy artillery, the aftermath of battle, and the terror that these young men faced. See first-hand of Union and Confederate officers strategizing their next moves, and Abraham Lincoln addressing his Union commanders. Originally released from the private collection of Edward Bailey Eaton in 1907, this edition is a must have for any Civil War buff or historian. No collection can be considered complete without these photographs by Matthew Brady and Alexander Gardner, as well as the meticulous passages that put the images in illuminating context.
This manual provides engineer doctrine for operating at the BCT level and below and within the framework of unified land operations. The engineer support doctrine for the BCT is focused on tactical-level maneuvers. The engineer organizations that are organic to the BCT are optimized to perform combat engineering tasks (primarily mobility with limited capabilities in countermobility and survivability). Geospatial engineering support is provided by organic terrain teams. Additional engineering support (combat and general) comes from engineer organizations that are task-organized to the BCT or that provide support from echelons above brigade (EAB) organizations. This manual is aligned with current BCT doctrine and describes engineer support for the armored BCT, infantry BCT, and Stryker BCT. Although the armored cavalry regiment and engineer company are not specifically addressed, the basic principles of this manual also apply to those organizations. This manual also provides greater detail for commanders and staffs at brigade echelons and below to ensure the synchronization of engineer capabilities across the range of military operations. Many of the tactical tasks associated with combat and general engineering support have remained constant although current and proposed future operational environments have dramatically shifted with the emergence of new threats (such as improvised explosive devices [IEDs]) and an increased emphasis on stability operations. Another significant change involves Army reorganization and restructuring of the force and the effects that they have on doctrine and operations. Changes that directly affect this manual include the-Restructure of engineer organizations within each of the three types of BCTs and within the armored cavalry regiment; Likelihood that the operations conducted will be with unified action partners. (The primary focus of joint engineer operations is to achieve the commander's intent by coordinating engineer support throughout the joint area of operations.); Alignment of engineer doctrine that supports BCTs; Consequential changes in the basic Army organizational structure and equipment of engineer organizations.
This publication, Army Techniques Publication ATP 3-34.23 Engineer Operations - Echelons Above Brigade Combat Team June 2015, describes engineer operations at echelons above brigade (EAB) combat team level. It is the doctrinal manual for engineer support to division, corps, and theater Army echelons. This manual is an extension of FM 3-34 and is linked to joint and Army doctrine to ensure that it is useful for operational commanders and staffs. This manual serves as a guide for the application of engineer combat power and the employment of engineer forces in support of decisive action primarily at higher echelons and within a joint framework. The principal audience for ATP 3-34.23 is engineer commanders and trainers at higher echelons. This manual forms the foundation for the engineer curriculum contained in the engineer portions of the Army Education System. The information contained in this manual will assist multinational forces and other Services and branches of the Army in planning and integrating engineer capabilities. This manual will also assist Army branch schools in teaching the integration of engineer capabilities into Army and joint operations. This manual describes the engineer operations integrated through the warfighting functions in a combined arms application of combat power. It describes the engineer capabilities available to commanders and provides information for force-tailoring these capabilities at higher echelons to ensure synchronization throughout the operations process and across the range of military operations. It discusses the foundation of engineer operations to ensure integration at each echelon and develops considerations for engineer operations within the operations process, tailored organization, range of military operations, and headquarters configuration unique to the division, corps, and theater Army echelons. This manual emphasizes the simultaneous combination of offensive, defensive, and stability or defense support of civil authorities (DSCA) tasks. It describes engineer support to Army forces conducting decisive action within the framework of joint operations. It also addresses the engineer roles and functions with unified action partners (potentially under multinational or interagency leadership) and within diverse command relationships. The manual is organized into 5 chapters and 3 appendixes that provide additional details on selected operational topics. A brief description of each chapter is below: Chapter 1 describes the engineer view of the operational environment as it pertains to operations at EAB combat team. It describes the forces and capabilities available (including unified action partners) and addresses the tailoring of engineer force pool capabilities in support of engineer operations. Chapter 2 lays the foundation for engineer operations at EAB. It focuses on integration at each echelon and throughout the operations process. It discusses the engineer staff by echelon, capabilities within the engineer disciplines, and synchronized application of these capabilities through the warfighting functions. Chapter 3 describes engineer operations at the theater echelon. It discusses integration into the theater Army design methods, force-tailoring considerations at the theater echelon, and engineer support in each of the operational configurations described for a theater Army headquarters. Chapter 4 describes engineer operations at the corps echelon. It discusses integration into the corps operations processes, force-tailoring considerations, decisive action at the corps echelon, and engineer support in each of the operational configurations described for a corps headquarters. Chapter 5 describes engineer operations at the division echelon. It discusses integration into division operations processes, force-tailoring considerations, decisive action at the division echelon, and engineer support in each of the operational configurations described for a division headquarters.
The Department of Defense Law of War Manual belongs on the shelf of every researcher, journalist, lawyer, historian, and individual interested in foreign affairs, international law, human rights, or national security. The Manual provides a comprehensive, authoritative interpretation of the law of war for the U.S. Department of Defense.
The engineer support doctrine for the brigade combat team (BCT) is focused on tactical-level maneuvers. The engineer organizations organic to the BCT are optimized to perform combat engineering (primarily mobility with limited capabilities in countermobility and survivability) tasks with geospatial engineering support provided by the organic terrain teams. Additional engineering support (combat and general) comes from modular engineer organizations that are task-organized to the BCT or providing support from echelons above brigade (EAB) organizations. This manual is aligned with current BCT doctrine (see Field Manual [FM] 3-90.6) and describes engineer support for the heavy brigade combat team (HBCT), infantry brigade combat team (IBCT), and Stryker brigade combat team (SBCT). Although the armored cavalry regiment (ACR) and its engineer company is not specifically addressed, the basic principles of this manual also apply to those organizations. This manual serves as a reference document for engineer commanders, staff, leaders, training developers, and doctrine developers throughout the Army. It is a primary manual for instructional purposes within the U.S. Army Engineer School (USAES) and assists other Army branch schools in teaching the integration of engineer capabilities into Army operations, since engineer involvement is a given for nearly every military operation. This manual includes guidance on integrating organic and augmenting engineer forces into BCT tactical plans, orders production, and mission execution. It incorporates the use of essential tasks for mobility, countermobility, and survivability (M/CM/S) in BCT operations and highlights the organic and likely engineer augmentation to the BCT as it operates across the spectrum of conflict.
