Army Tactics and Procedures (ATP) 3-20.16 covers the mobile gun system platoon's organization and functions; its internal roles and responsibilities as well as its roles within the Stryker brigade combat team Infantry rife company; the platoon's capabilities and limitations; and the doctrinal guidance, tactics, and procedures the platoon uses in unified land operations. ATP 3-20.16 provides doctrinal guidance for commanders, staff, and leaders, who plan, prepare, execute, and assess operations of mobile gun system platoons. It is also intended for mobile gun system platoon leaders, platoon sergeants, team leaders, Stryker brigade combat team company level leaders, and supporting units. It serves as an authoritative reference for personnel who develop doctrine (fundamental principles and tactics, techniques, and procedures), material and force structure, institutional and unit training, and mobile gun system platoon standard operating procedures. The doctrinal principles and procedures contained in ATP 3-20.16 are to be used as a guide and are not considered prescriptive. ATP 3-20.16 outlines the framework in which mobile gun system platoons operate, either alone or together as part of the combined arms company team. ATP 3-20.16 also includes discussions of doctrine applicable to all mobile gun system platoons. This publication applies to the Active Army, Army National Guard (ARNG)/Army National Guard of the United States (ARNGUS), and the United States Army Reserve (USAR) unless otherwise stated. The proponent for this publication is the United States Army Training and Doctrine Command. The preparing agency is the U.S. Army Maneuver Center of Excellence.

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.

This publication, Army Techniques Publication ATP 3-21.8 Infantry Platoon and Squad April 2016, provides the doctrinal framework for all Infantry platoons and squads. It provides techniques for employment of Infantry platoons and squads in conducting decisive actions. The principle audiences for ATP 3-21.8 are commanders, staffs, and leaders who are responsible for planning, preparing, executing, and assessing operations of the Infantry platoon and squad. It serves as an authoritative reference for personnel developing doctrine materiel and force structure, institutional and unit training, and standard operating procedures (SOPs) for Infantry platoon and squad operations. Army Techniques Publication (ATP) 3-21.8 encompasses techniques for the Infantry platoons and squads of the Infantry, Stryker, and Armored brigade combat teams (I, S, and ABCTs). It replaces Field Manual (FM) 3-21.8, published in March 2007, Army Tactics Techniques, and Procedures (ATTP) 3-21.71, published in November 2010, and ATTP 3-21.9, published in December 2010. ATP 3-21.8 provides doctrinal guidance; describes relationships within the platoon and squad; defines organizational roles and functions, capabilities, limitations; and lay outs the responsibilities for platoons and squads during unified land operations. The Infantry platoon and squad is an all-weather, all-terrain unit. Against this backdrop, the Infantry platoon and squad must be ready to adapt to various levels of conflict and peace in various environments. This requires bold, aggressive, resourceful, and adaptive leaders- leaders of character, competence and commitment - who are willing to accept known risks to accomplish the mission. Infantry leaders must use their initiative and make rapid decisions to take advantage of unexpected opportunities. This publication addresses the significant changes in Army doctrinal terminology, concepts, and constructs and proven tactics, techniques, and procedures (TTPs): Chapter 1 - Organization Chapter 2 - Offense Chapter 3 - Defense Chapter 4 - Stability Chapter 5 - Movement Chapter 6 - Patrols and Patrolling Chapter 7 - Sustainment Appendix A describes the process of troop leading procedures (TLPs). Appendix B describes direct fire planning and control. Appendix C describes indirect fire support planning. Appendix D addresses security. Appendix E describes vehicle employment considerations. Appendix F addresses machine gun employment. Appendix G describes and addresses shoulder-launched munitions (SLMs) and close combat missile systems (CCMS). Appendix H describes obstacle reduction and employment. Appendix I covers chemical, biological, radiological, and nuclear (CBRN) operations. Appendix J describes 14 selected battle drills for both the Bradley and Stryker. ATP 3-21.8 applies to the active Army, the U.S. Army National Guard, Army National Guard of the U.S., and the U.S. Army Reserve unless otherwise stated. It is designed for platoon, squad and company level chains of command, company grade officers, senior and junior noncommissioned officers (NCOs), U.S. Army Training and Doctrine Command (TRADOC) institutions and components, and the U.S. Army Special Operations Command.

For the US Army to succeed in the 21st Century, Soldiers of all ranks must understand and use Mission Command. Mission Command empowers leaders at all levels, allowing them to synchronize all warfighting functions and information systems to seize, retain, and exploit the initiative against a range of adversaries. This collection of historical vignettes seeks to sharpen our understanding of Mission Command philosophy and practice by providing examples from the past in which Mission Command principles played a decisive role. Some vignettes show junior officers following their commander's intent and exercising disciplined initiative in very chaotic combat operations. Others recount how field grade officers built cohesive teams that relied on mutual trust to achieve key operational objectives. Each historical account is complemented by an annotated explanation of how the six Mission Command principles shaped the action. For this reason, the collection is ideal for leader development in the Army school system as well as for unit and individual professional development. Mission Command places great responsibility on our Soldiers.

Volume 5, Deep Maneuver: Historical Case Studies of Maneuver in Large-Scale Combat Operations, presents eleven case studies from World War II through Operation Iraqi Freedom focusing on deep maneuver in terms of time, space and purpose. Deep operations require boldness and audacity, and yet carry an element of risk of overextension - especially in light of the independent factors of geography and weather that are ever-present. As a result, the case studies address not only successes, but also failure and shortfalls that result when conducting deep operations. The final two chapters address these considerations for future Deep Maneuver.
