The three most important things the Marine Corps does for the Nation are make Marines, win battles, and return quality citizens. Public affairs (PA) is an integral part of warfighting and solidifies the existing, indispensable bond between the Marine Corps and the American public. Professional, sophisticated PA is just as important as tactics and weapons training. As a powerful, nonlethal capability with application across the range of military operations, PA builds understanding, credibility, trust, and relationships with domestic and foreign publics-publics that are critical to the Marine Corps' mission success and the Nation's larger strategic objectives. Marine Corps Techniques Publication MCTP 3-30F (Formerly MCWP 3-33.3) Marine Corps Public Affairs 2 May 2016, describes Marine Corps doctrine on PA. It provides the requisite information needed by commanders and their staffs to understand PA. Although this publication is particularly relevant for Marine air-ground task force commanders and their staffs, it is important for every Marine to understand the information contained herein. This publication addresses the information environment, the news media, policies and principles governing PA, and command responsibility for PA.

Marine Corps Tactical Publication MCTP 3-01C (Formerly MCWP 3-15.1) Machine Guns and Machine Gun Gunnery 2 May 2016 describes how various machine guns are maintained and employed by the U.S. Marine Corps' machine gun crews. It also provides the principles and techniques for their use in engaging and destroying enemy targets.

The authors present a methodology to determine optimal personnel capacity for Marine Corps intermediate-level supply accounts and other measures to help these accounts work more effectively and efficiently to meet supported units' needs.

Marine Corps Reference Publication, Religious Ministry Team Handbook, guides commanders, chaplains, Religious Program Specialists, and lay leaders in providing religious ministry and effective command religious programs.

Doctrine provides a military organization with a common philosophy, a language, a purpose, and unity of effort. Rather than establishing a set of hard and fast rules, the objective of doctrine is to foster initiative and creative thinking. To this end, FM 3-06 discusses major Army operations in an urban environment. This environment, consisting of complex terrain, a concentrated population, and an infrastructure of systems, is an operational environment in which Army forces will operate. In the future, it may be the predominant operational environment. Each urban operation is unique and will differ because of the multitude of combinations presented by the threat, the urban area itself, the major operation of which it may be part (or the focus), and the fluidity of societal and geopolitical considerations. Therefore, there will always exist an innate tension between Army doctrine, the actual context of the urban operation, and future realities. Commanders must strike the proper balance between maintaining the capability to respond to current threats and preparing for future challenges.

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.
