Engineer Operations - Echelons Above Brigade Combat Team (ATTP 3-34.23)

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.
