The manual describes the general strategy for the U.S. Marines but it is beneficial for not only every Marine to read but concepts on leadership can be gathered to lead a business to a family. If you want to see what make Marines so effective this book is a good place to start.

Field Manual (FM) 3-90 Volume 1 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 basictactics associated with the conduct of offensive and defensive tasks.

This field manual establishes doctrine for military operations in a counterinsurgency (COIN) environment. It is based on lessons learned from previous counterinsurgencies and contemporary operations. It is also based on existing interim doctrine and doctrine recently developed. Counterinsurgency operations generally have been neglected in broader American military doctrine and national security policies since the end of the Vietnam War over 40 years ago. This manual is designed to reverse that trend. It is also designed to merge traditional approaches to COIN with the realities of a new international arena shaped by technological advances, globalization, and the spread of extremist ideologies--some of them claiming the authority of a religious faith. This is a comprehensive manual that details every aspect of a successful COIN operation from intelligence to leadership to diplomacy. It also includes several useful appendices that provide important supplementary material.

This manual, Marine Corps Warfighting Publication MCWP 3-01 Offensive and Defensive Tactics September 2019, comprehensively addresses the philosophy of tactics in general and offensive and defensive tactics specifically, across the range of military operations. It does not specifically discuss stability doctrine, tactics, or operations; although it does contain guidance for simultaneously recognizing, executing, and transitioning between offense, defense, and stability activities.Marine Corps Warfighting Publication MCWP 3-01 Offensive and Defensive Tactics September 2019is the Marine Corps' basic warfighting offensive and defensive tactics publication. MCWP 3-01 serves as a common starting point for leaders and units to address the specific tactical problems that face them. It is a compendium of best practices and common terms, not a dictate that must be rigidly adhered to. MCWP 3-01 provides the basics of offensive and defensive tactics from the squad level to the Marine division and points the reader to references for further study.This publication is intended for the Marines, leaders, commanders, and staffs from the squad level to the Marine division as a foundational document to assist in the preparation and execution of offensive and defensive tactics in any given operational environment.

FM 3-97.6, "Mountain Operations," describes the tactics, techniques, and procedures that the United States (US) Army uses to fight in mountainous regions. It is directly linked to doctrinal principles found in FM 3-0 and FM 3-100.40 and should be used in conjunction with them. It provides key information and considerations for commanders and staffs regarding how mountains affect personnel, equipment, and operations. It also assists them in planning, preparing, and executing operations, battles, and engagements in a mountainous environment. Army units do not routinely train for operations in a mountainous environment. Therefore, commanders and trainers at all levels should use this manual in conjunction with TC 90-6-1, Army Training and Evaluation Program (ARTEP) mission training plans, and the training principles in FM 7-0 and FM 7-10 when preparing to conduct operations in mountainous terrain.

Doctrine provides a military organization with unity of effort and a common philosophy, language, and purpose. This manual, "Theater Army Operations" (FM3-93), discusses the organization and operations of the theater army headquarters, including its role as the Army Service component command (ASCC) to the geographic combatant commander (GCC) and the relationships between the theater army headquarters and the theater enabling commands. The manual also discusses theater army responsibilities for setting the theater, Title 10 functions and responsibilities, generally referred to as the combatant commander's daily operations requirements, as well as the operational employment of the theater army's contingency command post (CCP) to directly mission command limited types of operations.

The Army and joint force must adapt and prepare for large-scale combat operations in highly contested, lethality to exploit. The reduction of friendly, forward-stationedforces, significant reductions in capability and capacity across the entire joint force, and the pace of modernizationmake it imperative that we do everything possible to prepare for worst-case scenarios. We must be ready to winwith the forces we have, and having the right doctrine is a critical part
