Field Manual FM 3-90-1 Offense and Defense Volume 1 Change 2 April 2015 contributes to the Army and joint community by providing guidance on the conduct of the offense and defense. It describes both combat-tested tactics and procedures that have been modified to exploit emerging Army and joint offensive and defensive capabilities. FM 3-90-1 expounds on the doctrinal fundamentals established in Army Doctrine Reference Publication (ADRP) 3-90. ADRP 3-90 must be read before reading FM 3-90-1, since that is where doctrine for the conduct of offensive and defensive tasks and the art and science of tactics is found. FM 3-90-1 addresses the basic tactics associated with the conduct of offensive and defensive tasks. The principal audience for FM 3-90-1 is all members of the profession of arms. Commanders and staffs of Army headquarters serving as a joint task force or multinational headquarters should also refer to applicable joint or multinational doctrine concerning the range of military operations and joint or multinational forces. Trainers and educators throughout the Army will also use this publication. FM 3-90-1 focuses on the organization of forces, minimum essential control measures, and general planning, preparation, and execution considerations for each primary offensive and defensive task. It is the common reference for all students of the art and science of tactics, both in the field and the Army school system. The offensive and defensive considerations in this publication apply to small tactical units, such as companies and battalions, even though most of the figures in this publication use the division and the brigade combat team (BCT) echelons to illustrate points in the text. Echelon-specific field manuals and Army techniques publications address the specifics of how each tactical echelon employs these tactical concepts.

It has been nearly thirty years since a holistic explanation of the Soviet-based Opposing Force (OPFOR) was examined in the U.S. Army Field Manual 100-2 series. Recognizing this, ¿OPFOR SMARTbook 3: Red Team Army¿ re-examines and outlines the doctrinal operational construct and historical foundations of Soviet-era military forces from the FM 100-2 series, which is now out-of-print and largely unavailable. Second, OPFOR SMARTbook 3 reorganizes that foundational material and aligns it in keeping with contemporary military doctrinal taxonomy to include ADRP 3-0 Unified Land Operations and ADRP 3-90 Tactics. Third, OPFOR SMARTbook 3 translates and bridges the strategic- and operational-level doctrine into tactical application at the small-unit level. Through this triangulation, a more modern rendition of Red Team Armies emerges. *** Find the latest edtion of this book and the rest of our series of military reference SMARTbooks at the publishers website: www.TheLightningPress.com ***
