This United States Army and United States Marine Corps manual, Army Techniques Publication ATP 3-34.40 MCTP 3-40D (MCWP 3-17.7) General Engineering April 2023, provides doctrine for the conduct of general engineering support by the Army and Marine Corps. It emphasizes the general engineering unity of effort by providing a common philosophy, language, and purpose. General engineering is a joint and Marine Corps engineering function and an Army discipline. This publication discusses how general engineering enables commanders to achieve their objectives in supporting multinational, joint, and service-specific missions. This publication also introduces subordinate doctrine.
This manual builds on the collective knowledge, wisdom, and military expertise gained through recent operations, numerous lessons learned, and doctrine revisions. This publication describes how engineer commanders, staffs, and subordinate leaders conduct general engineering to support Army and Marine Corps forces within the framework of joint and multinational operations.
The general engineering doctrine provided in this manual presents an overview of a wide range of topics and allows the reader to understand how the topics fit together. The engineer must refer to the referenced materials throughout the manual to gain a complete understanding of the general engineering life cycle activities. This manual is not meant to be a substitute for the creative thought, innovation, and initiative among engineer leaders, Soldiers, or Marines. Rather, its intent is to build, enhance, and strengthen their present knowledge and understanding. General engineers take their training, experience, capabilities, and understanding of doctrine and apply them to solve and unravel unique and obscure challenges to meet operational needs.
