The purpose of this manual, Army Doctrine Publication ADP 7-0 Training August 2018, to provide the Army the framework leaders follow to effectively ready Soldiers and units to execute unified land operations. Readiness is the Army's number one priority, and training represents the most important activity units do every day to achieve readiness. The Army does this by conducting tough, realistic, standards-based, performance-oriented training. ADP 7-0 is founded on the concept that training management is a logical extension of the Army's operations process. The ideas and concepts of planning, preparing, executing, and assessing operations is fundamentally the same whether the unit trains to achieve readiness at home station or trains to operate when deployed. Learning and applying the concepts, ideas, and terminology of the operations process as units train makes the transition from training to operations more seamless for both leaders and their units-and improves the overall readiness of the force. ADP 7-0 contains four chapters: Chapter 1 introduces the Army's overarching concepts of training Soldiers and units to conduct operations. This chapter discusses the links between unit training and the Army's fulfillment of its strategic roles. It explains the foundations of the Army task hierarchy as individual and collective tasks and the mutually supporting relationship between them. The chapter also introduces the concept of multiechelon training as the primary method of simultaneously training several echelons to replicate how units operate when employed for operations. It discusses a commander's responsibility for developing subordinate leaders, ensuring that trained, competent, and certified leaders lead all unit training. Chapter 2 discusses a commander's pivotal role and activity in training the unit. It discusses the activities of understand, visualize, describe, direct, lead, and assess as the mechanisms commanders employ to drive unit training. The chapter reinforces the necessity of the commander as the unit's primary trainer who determines the tasks to train, the methods the unit will use, and the subordinate leaders' understanding of the standards to attain. The chapter emphasizes the shared and mutual understanding that must exist between the commander and subordinate leaders to ensure unit training proficiency is achieved. Chapter 3 introduces a detailed discussion of each of the Army's principles of training. Units employ effective training based on an understanding and application of the Army's principles of training. These principles provide a broad but essential foundation to guide unit commanders and leaders as they plan, prepare, execute, and assess sustained and effective training. The chapter provides leaders with a base understanding of the most effective concepts of training which are elemental to developing the skills necessary to conduct successful operations. Each principle provides an enduring and central tenet to how all leaders think about and conduct unit training. Chapter 4 describes the major actions and procedures units perform as training is conducted. The chapter begins by discussing the measures of training proficiency and transitions into the concept of battle-focused training-training that develops required operational skills and capabilities. Top-down training guidance provided by the higher commander begins the planning process for subordinate units to develop the most effective training plan possible. The chapter covers how units plan, prepare for, execute, and assess each training event in challenging conditions with the highest fidelity of realism. Training performance is objectively evaluated with the results providing the commander the firm basis for an accurate assessment of unit operational skills and capabilities. The commander's training assessments become the basis of training readiness reporting.
