Abstract:
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.

Abstract:
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.

Abstract:
Although 1775 is indisputably the birth year of the US Army, two events occurred on June 14 of that year to which the Army can credit its birthday. One is the adoption by the Continental Congress of the collective militia forces from several colonies outside Boston to form a Continental Army, of which Congress appointed George Washington the commander in chief on June 15, 1775. In addition, the US Regular Army officially dates its beginning to June 14, 1775, when the Second Continental Congress directed 10 companies of expert riflemen to be raised immediately in Pennsylvania, Maryland, and Virginia. William Thompson’s commission as the colonel of the Pennsylvania Rifle Battalion was dated June 25, 1775, and made him the first colonel of what would eventually become, through George Washington’s Continental Army, the US Regular Army. But William Thompson has not found a prominent place in the American pantheon of revolutionary heroes for a variety of reasons. In addition, Thompson’s Pennsylvania Rifle Battalion later became the 1st Continental Regiment and ended the American Revolution as the 1st Pennsylvania Regiment, but its lineage has not continued in the modern US Army.

Abstract:
The essays in this volume analyze Germany’s Zeitenwende, a pivotal shift in security policy triggered by Russia’s reinvasion of Ukraine in February 2022. Key topics include national security strategy, defense policy, energy policy, industrial strategy, and international relations with Russia, China, the United States, NATO, and the EU. Regarding strategy, Germany’s approach lacks focus, offering broad goals without addressing trade-offs or specific threats. On defense policy, the Zeitenwende marked a renewed commitment to defense spending, bolstered by a €100 billion modernization fund. But delays in procurement, operational shortcomings, and an underfunded long-term defense budget hinder Germany. Similar challenges affect the defense industry, despite increased spending and exports. In energy policy, Germany rapidly diversified energy sources and expanded its liquefied natural gas infrastructure to reduce its dependence on Russian gas. Still, achieving energy security, affordability, and sustainability remains complex. Internationally, Germany abandoned decades of Ostpolitik, prioritizing Ukraine over ties with Russia. Germany’s evolving China policy focuses on derisking and maintaining economic ties, raising questions about whether Berlin has reduced vulnerabilities. Though Washington supports Germany’s strategic shift, concerns remain about its sustainability, particularly in Germany’s NATO and EU commitments. Each chapter concludes by identifying the implications for the United States as well as the steps to overcome identified challenges.

Abstract:
Innovative new thinking on the security dimension of the challenges posed by the PRC’s engagement in Latin America and the DoD’s role in the whole-of-government US response is needed. This monograph highlights risks from PRC influence networks, digital architectures, and dual-use commercial facilities in the region, particularly at ports and in the space sector; shows how PRC economic engagement and other support sustains illiberal regimes, indirectly contributing to the risks these regimes pose by hosting criminal and terrorist groups and other US adversaries, such as Russia and Iran; and illustrates how commercial, people-to-people, and security engagements create options for the PRC to exploit against the United States in times of war. It advocates for new effects-based strategic concepts for how the DoD can strengthen cooperation with the region and limit PRC access through enhanced security cooperation and leveraging partners’ valuation of their relationships with the United States to influence their choices regarding cooperation with the PRC and gain better situational awareness for responding to China. Finally, it discusses how the United States should work with regional partners to plan for likely PRC actions in the region in times of war, leveraging the presence, relationships, and knowledge created through engagement.

Abstract:
As China continues to rise as a global sea power, its maritime strategy continues to evolve. Among these critical evolutions is one of the People’s Liberation Army’s naval special operations forces’ most elite units: the Sea Dragons. A small yet highly specialized unit, the Sea Dragons entered the global spotlight and international consciousness with the 2018 film Operation Red Sea, raising several questions for Chinese naval experts. What does Chinese military strategy and doctrine require of special forces, and specifically naval SOF, to be able to accomplish the mission, particularly along the Taiwan Strait and in the South China Sea? What are their capabilities and limitations? What real-world experience do they have and how might they be employed in the future? This volume attempts to answer those questions and many more regarding one of China’s more enigmatic units and its role in future peacetime and low-intensity conflicts.

Abstract:
The MENA countries have been confronting profound and far-reaching climate shocks. Experts widely agree that human-driven activity intensely shapes escalating climate stressors—including extreme weather events—dwindling natural resources, and persistent environmental degradation. These climate dynamics are expected to deepen existing conflicts, destabilizing an already fragile landscape. Conflict contributes to further visible environmental deterioration, leaving a trail of devastation in its wake. Despite this intimate interplay, environmental and climate considerations are often ignored during peacebuilding efforts. More than ever, the situation in the region is shaped by conflict and war. The climate-conflict nexus takes on greater urgency in the Middle East and North Africa. The unpredictable security situation, coupled with rapidly changing conditions on the ground, has presented challenges for this publication: the inclusion of a dedicated chapter on Lebanon had to be reconsidered due to war. The remaining country analyses, however, capture and present the current situation. This publication marks a collaborative effort between the Arab Reform Initiative and the Robert Bosch Stiftung as part of our joint program, “Conflict, Climate Change and Environment in the Middle East”, which we launched in 2021. The program’s central aim is to create spaces for exchange and sharing expertise among diverse local, national and regional actors, practitioners, and scholars from the MENA. By fostering these connections across sectors and geographies, we are building networks and alliances that support local actors, amplifying the voices of those most affected by both conflict and environmental change. Due to unforeseeable events on the ground, some of the chapters in this publication have been rendered outmoded, a testament to the environment’s volatility during times of conflict. We extend our deep gratitude to the dedicated contributors of this publication, particularly Hussam Hussein, Sammy Kayed, and Tobias Zumbraegel, whose commitment has helped bring this work to fruition; and to the authors’ meticulous contributions towards each of the chapters. Special thanks go to Zaki Boulos for his careful editorial guidance. Lastly, we are grateful to all the local stakeholders and sources who enriched this publication with their insights and expertise, adding depth and nuance to the analyses. This publication is both a call to action and a resource, designed to catalyze collaboration and informed action on the complex relationship between climate, conflict, and environment in the MENA. We look forward to continuing this vital work alongside all those committed to building resilience and fostering sustainable peace in the region.

Abstract:
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.

Abstract:
Integrating Artificial Intelligence and Machine Learning Technologies into Common Operating Picture and Course of Action Development explores the potential of artificial intelligence (AI) and machine learning to revolutionize military planning processes by enhancing situational awareness and expediting course of action development within the Joint planning process. The study delves into technical, organizational, and resource considerations that are critical for AI integration. In addition, the study highlights the importance of clean, structured data in training AI systems, addresses challenges in data collection across varying formats and classifications, and emphasizes the need for AI-friendly infrastructure. By automating processes like common operational picture generation and leveraging AI for course of action analysis, military planners can achieve greater efficiency and decision-making speed. Furthermore, this publication underscores the challenges of ethical implementation, resource sustainability, and organizational adaptation, including upskilling personnel and integrating commercial vendors. Case studies, such as the Maven Smart System and STORMBREAKER, demonstrate AI’s ability to enhance data fusion, improve battlefield awareness, and streamline operational planning. This research provides a robust framework for overcoming barriers to AI adoption, enabling the US military to harness AI technologies for enhanced planning, decision making, and operational success.

10. Weaponizing Risk: Recalibrating Western Deterrence

Author:

Abstract:
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.
