ADP 3-0 Operations In 2011 the Army updated its warfighting doctrine to conduct unified land operations executed through decisive action and guided by mission command. ADP 3-0, Operations,is a natural evolution of past capstone doctrine that captured the most critical lessons of almost fifteen years of sustained land combat. In this edition, we not only reflect on the past but also look to the future. This publication builds on the idea that success requires fully integrating Army operations with the efforts of unified action partners. ADP 3-0 provides a common operational concept for Army forces who must be ready to operate across the range of military operations and across multiple domains, integrating their actions with unified action partners as part of a larger effort. Today, Army forces are engaged with more than 140,000 Soldiers in over 150 countries, either conducting combat operations, deterring aggression, or reassuring our allies and partners. The United States Army is also relentlessly hunting terrorists throughout many other parts of the world. We are engaging our partners in Africa and throughout the Americas. Readiness for current and future operations requires a force that is honed through effective training and education and well versed on how our Army conducts operations. The central idea of operations is that, as part of a joint force, Army forces seize, retain, and exploit the initiative to gain and maintain a position of relative advantage in sustained land operations to prevent conflict, shape the operational environment, and win our Nation’s wars as part of unified action. ADP 3-0 discusses the principles of unified land operations—mission command, develop the situation through action, combined arms, adhere to the law of war, establish and maintain security, and create multiple dilemmas for the enemy. ADP 3-0 incorporates the tenets of unified land operations—simultaneity, depth, synchronization, and flexibility. It highlights the concept that operational art is the connection between strategic objectives and tactical actions, and it supports a common construct for organizing both joint and Army operations. The construct consists of the Army operations process, an operations framework for visualizing and describing operations, and combat power. ADP 3-0 serves as the common operational concept for the Army. The central idea, adapted to the unique conditions of each conflict, represents the Army’s unique contribution to unified action. It must permeate our doctrine, our training, and our leader professional development programs.
