Joshua Arostegui, Editor; Conference papers from the US Army War College, Strategic Studies Institute, US Army War College Press; The US Army War College’s 2024 Carlisle Conference on the People’s Liberation Army was held on October 16 and 17 at Carlisle Barracks, Pennsylvania. The conference featured keynote speakers from the US Department of Defense and the think-tank community, and panels focused on assessing the People’s Republic of China’s understanding of and capability to carry out a protracted war in the Indo-Pacific. The conference brought together over 100 participants from government, military, US Intelligence Community, academic, and think-tank organizations. The conference papers were authored by expert speakers and panelists and were designed to provide insight into key People’s Republic of China and People’s Liberation Army advances that could enable Chinese forces in a future protracted war against a US-led coalition. The papers were also crafted to enable in-depth seminar discussions following each panel, allowing the authors to garner feedback to improve their analyses.= The conference volume is organized into four sections based on the conference panels: understanding the People’s Republic of China’s views on historical and modern protracted wars; assessing the People’s Liberation Army’s operational endurance in the land, maritime, and air domains; analyzing China and the People’s Liberation Army’s ability to command and control a protracted war; and determining how Russia and North Korea could support the People’s Republic of China in a protracted war.

John A. Nagl, Project Director, and Michael T. Hackett, Chief of Staff; Integrated Research Project from the US Army War College, Strategic Studies Institute, School of Strategic Landpower, US Army War College Press; Following the 2024 A Call to Action: Lessons from Ukraine for the Future Force, which explored military lessons learned from the first year of the Russia-Ukraine War, this book examines the changing character of war as the second year of the war unfolded. This year’s authors explore the conflict from four different angles: information advantage (intelligence, information operations, and cyber); landpower operations (fires, maneuver, force protection, mission command, and mercenaries); multi-domain operations (air and maritime); and crosscutting themes (diplomacy, sustainment, and innovation and adaptation). The second year witnessed the innovative approaches to combat of the first year—drones, unmanned aerial systems, and electronic-warfare offensive and defensive capabilities—combined with entrenched warfare not seen at the current scale in Europe since World War I. The use of mercenary private military companies like the Wagner Group generated moments of high suspense (with a failed mutiny in July 2023) and led to changes in Russian force structure and tactics. Delays in continued allied support tested the resolve and operational capabilities of the Armed Forces of Ukraine, which nevertheless kept up the fight and held Russia back. Through it all, the conflict offers a compelling picture of the war of the future, along with lessons for the US Army Training and Doctrine Command to prepare the Joint Force to meet the challenges of the large-scale combat operations of tomorrow. ©2026 John A.

by Brennan Deveraux; Monograph from the US Army War College, Strategic Studies Institute, US Army War College Press; This monograph challenges the Department of War to reframe the conversation about humans’ involvement in lethal autonomous weapons systems by codifying a human-centric framework built on the employment pillars of certification, authority, restriction, and accountability. Although an ample body of literature discusses lethal autonomous weapon systems, this monograph takes a novel approach by proposing a theoretical framework and applying it to historical and hypothetical practical scenarios involving weapons with autonomous characteristics. In terms of methodology, the monograph relies heavily on primary sources, including UN documents and Department of War publications, which are augmented by secondary sources from experts in the field and creative speculation about the characteristics of future warfare. The study’s conclusions will help US military and policy practitioners manage and integrate lethal autonomous weapon systems. This study is designed to spark a necessary and likely uncomfortable conversation about when relying on lethal machines is appropriate. The monograph provides tangible recommendations to help shape future policy decisions about developing and employing lethal autonomous weapon systems.

Antulio J. Echevarria II, Larry P. Goodson, and Brennan Deveraux – Project Directors; Integrated Research Project from the US Army War College, Strategic Studies Institute, US Army War College Press; The US government and the US Army are unprepared for a great-power war. This integrated research project (IRP), sponsored by Vice Chief of Staff of the Army General James J. Mingus, is a critical first step in helping senior US Army leaders increase their knowledge of, and preparations for, deterring or fighting a great-power war in the twenty-first century. No one knows how long the US government and the US Army have to prepare for a future conflict. Consequently, the US Department of Defense faces difficult decisions as it balances preparing for a future war with maintaining readiness to address current challenges. The student research in this IRP only scratches the surface of what the US Department of Defense and the US Army should do to understand, deter, and prepare more effectively for the possibility of a great-power war in the twenty-first century. While the steps outlined here are preliminary, they are not tentative. Readers will find that each chapter offers concrete, actionable recommendations based on duly considered analysis. But more work lies ahead.

Antulio J. Echevarria II; Monograph from the US Army War College, Strategic Studies Institute, US Army War College Press; This monograph discusses how NATO might better leverage risk to strengthen the alliance’s extended deterrence. Such leverage would prove especially useful because Kyiv is unlikely to be permitted to join NATO and the United States may reduce its presence in Europe. Western analysts have not given Russian deterrence enough credit for the alliance’s deterrence failure on February 24, 2022. The alliance did not act fecklessly, nor did it self-deter. Rather, NATO’s deterrence measures were calibrated more for hybrid/gray-zone attacks of the sort it saw in 2014, not for the large-scale combat operations the alliance witnessed in 2022, which involved a nuclear-armed adversary with stronger interests in Ukraine than NATO had. To be sure, the alliance’s leaders acted responsibly in managing the risk of escalation. But in so doing, they also facilitated Russian deterrence efforts, which succeeded in keeping Washington and Brussels from intervening in the war. The alliance thus demonstrated its need for a strategy that would increase the risks and costs of war for Russia without unduly raising NATO’s. In short, the alliance needs a proxy strategy of “waging war without going to war,” whereby NATO can provide its full political, economic, and military support to Ukraine without running the risk of putting alliance troops in harm’s way.

Brennan Deveraux and Joshua Arostegui; Monograph from the US Army War College, Strategic Studies Institute, US Army War College Press; This monograph establishes a contextual baseline that serves as the framework for future comparisons of the US Army and the People’s Liberation Army Army. It examines differences in five key components of land warfare: the two nations’ landpower definitions, uses of land forces to build relationships, underlying warfare concepts, associated modernization efforts, and varying approaches to simulating land warfare in the region. In examining these components, the authors identify warfare intangibles that highlight analytical findings in a way that promotes future research. The existing scholarship comparing the two forces is often limited in scope, focusing on funding or comparing capabilities such as the number of specific weapons systems. This monograph differs from existing scholarship by providing a broad, in-depth comparison of critical landpower components. The analysis challenges long-held assumptions about US Army superiority and sets a foundation for future research. The authors rely heavily on primary sources and ample secondary documents translated directly from Chinese vernacular sources. This study’s conclusions challenge conventional thinking surrounding the People’s Liberation Army and will assist US military and policy practitioners in assessing the relative strengths and advantages the US military can grow or exploit.
