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.

Army Tactics, Techniques, and Procedures (ATTP) 3-34.23, “Engineer Operations – Echelons Above Brigade Combat Team,” describes engineer operations at echelons above brigade (EAB) combat team level. It is the engineer doctrinal manual for engineer support to division, corps, and theater army echelons. The manual is an extension of Field Manual (FM) 3-34, and is linked to joint and Army doctrine to ensure its usefulness for operational-level commanders and staff. This manual serves as a guide for the application of engineer combat power and employment of engineer forces in support of full spectrum operations primarily at higher echelons and within a joint framework. ATTP 3-34.23 consolidates doctrine previously published in three separate manuals: FM 5-71-100, FM 5-100-15, and FM 5-116. The consolidated doctrine has been updated and revised to align with revisions to FM 3-34 and other Army and joint doctrine. ATTP 3-34.23 provides operational guidance for engineer commanders and trainers at all higher echelons and forms the foundation for established curriculum within the engineer portions of the Army's education system. Information contained in this manual will assist multinational forces and other Services and branches of the Army to plan and integrate engineer capabilities. This doctrine also will assist Army branch schools in teaching the integration of engineer capabilities into Army and joint operations.
The manual is organized into seven chapters plus numerous appendixes to provide additional details on selected operational topics. The first three chapters follow the flow of FM 3-34 and generally describe engineer operations at higher echelons. The next three chapters focus on operations at each of the higher echelons and operational configurations. The final chapter discusses sustainment support to the engineer forces operating at these echelons. A brief description of each of the chapters is provided below: Chapter 1 describes the engineer view of the operational environment (OE) as it pertains to operations at echelons above BCT. It discusses the challenges and opportunities that translate to requirements for engineer capabilities and combat power. It describes the forces and capabilities available including joint, interagency, and multinational forces. It concludes with a discussion of categorizing capabilities within the engineer functions and synchronizing their application through the warfighting functions. Chapter 2 discusses implications of the modular force organization for operations at higher echelons. It includes a discussion of the modular engineer force implications and the implications of the modular force headquarters at each higher echelon. It also addresses tailoring engineer force pool capabilities in support of engineer operations. Chapter 3 lays the foundations for engineer operations at EAB. It focuses on integration at each echelon and throughout the entire operations process. It includes a discussion of the engineer coordinator (ENCOORD). It also describes command and support relationships as the critical linkage for engineer integration throughout the force. Chapter 4 describes engineer operations at the theater echelon. It includes a discussion on integration in theater operational design, force-tailoring considerations, and operational themes at this echelon. It also includes a focused discussion on engineer support in each of the operational configurations described for a theater army headquarters. Chapter 5 describes engineer operations at the corps echelon. It includes a discussion on integration in corps operations processes, force-tailoring considerations, and full spectrum operations at this echelon. It also includes a focused discussion on engineer support in each of the operational configurations described for a corps headquarters. Chapter 6 describes engineer operations at the division echelon. It includes a discussion on integration in division operations processes, force-tailoring considerations, and full spectrum operations at this echelon. It also includes a focused discussion on engineer support in each of the operational configurations described for a division headquarters. Chapter 7 discusses sustainment of engineer capabilities. Successful engineer operations include effective incorporation of sustainment support. This chapter describes the integrated sustainment effort required to support engineer operations.
Field Manual (FM) 5-71-3 describes how the mechanized division endineer (DIVEN) battalion supports an armored brigade. The manual is designed as an engineer extension of FM 71-3. It serves as a guide for brigade engineers, their staffs and subordinate commanders in planning, integrating and conducting engineer operations. The manual also serves as a guide for the brigade staff and subordinate maneuver commanders on the organization, capabilities and employment of engineers as a brigade combat multiplier.

The consolidated doctrine has been updated and revised to align with revisions to FM 3-34 and other Army and joint doctrine. This revision has been driven by major changes to Army and joint doctrine, including: -- Revision of our Army's capstone manual, FM 3-0.-- Revision of Joint Publication (JP) 3-34.-- Revision of the engineer keystone manual FM 3-34.-- Lessons learned from experience fighting the war on terrorism.-- Conversion of the Army to a brigade combat team (BCT)-based, modular force that is joint andexpeditionary.-- Organization of the Engineer Regiment as the modular engineer force.-- Change from maintaining readiness within the "band of excellence" to achieving readiness through the force pool progression dictated by Army forces generation model.
This United States Army publication, Field Manual FM 3-34 Engineer Operations December 2020, contains the capstone doctrinal guidance for U.S. Army engineers. FM 3-34 demonstrates how engineers contribute to decisive action and provides a common framework and language for engineer support to operations. It also constitutes the doctrinal foundation for developing other fundamentals and tactics, techniques, and procedures detailed in subordinate engineer publications. This manual is the integrating publication that nests engineer doctrine with Army capstone doctrine and joint doctrine. It focuses on synchronizing and coordinating the diverse range of capabilities in the Engineer Regiment to support the Army and its mission successfully. FM 3-34 provides operational guidance for engineer commanders and trainers at all echelons and forms the foundation for the United States Army Engineer School (USAES) curricula. The principal audience for this manual is engineer leaders, commanders, noncommissioned officers, and staff officers, but all Army leaders benefit from reading it. Trainers, educators, and combat developers throughout the Army also benefit from using this manual.FM 3-34 applies to the Active Army, Army National Guard/Army National Guard of the United States and United States Army Reserve unless otherwise stated.
