Engineer Operations - Brigade Combat Team and Below (FM 3-34.22)

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.
