The AUSA Institute of Land Warfare (ILW) has recently released two new publications."The Army Operating Concept 2020-2040" (Defense Report 15-1, April 2015) outlines the challenging future operating environment that the Army faces.This environment is unknown, unknowable and constantly changing.To meet these challenges, the Army has created the new Army Operating Concept (AOC) to address prompt conduct of joint operations to prevent conflict, shape security environments and win wars.The AOC describes how the future Army forces will operate to accomplish campaign objectives and protect U.S. national interests by winning at the tactical, the operational and – most important – the strategic level of war.This paper should be of great interest to everyone who would like to know more about future threats facing the Army and the new Army Operating Concept (AOC) that has been created in anticipation of those challenges.************"The U.S. Army in Motion in the Pacific" (Torchbearer, April 2015) describes the complex and uncertain strategic operating environment that America’s Army faces in the future.To meet new challenges with success, the Army senior leadership has added two new concepts as core competencies that emphasize the Army’s role in providing options to joint force commanders across a range of operations.First, setting the theater, i.e., establishing a presence with the purpose of increasing capabilities and capacities.Second, shaping security environments, i.e., working to further both partner and allied relationships by fostering understanding and cooperation.While developing these concepts, the leadership has begun investing Army resources in the Indo–Asia–Pacific region.They are emphasizing a whole-of-government focus on the security and prosperity of that region, assigning a four-star general to the area and increasing the force assigned and available to the theater by approximately 40 percent.The Army now has an opportunity – through an innovation called Pacific Pathways – to put its new concepts into practice.These and other ILW publications are available online at http://www.ausa.org/ilw and can also be obtained by calling (800) 336-4570, Ext. 4630, or by e-mailing ilwpublications@ausa.org.
