By its very nature, urban warfare involves the presence of civilians. And when cities become battlefields, it may be necessary to evacuate noncombatants from them—either due to humanitarian imperatives or because military objectives require it. But an array of legal obligations and other considerations arise when civilians are evacuated. And because discussions of evacuations are closely linked to those surrounding the conduct of siege warfare, this raises further questions of the legal issues related to sieges and the obligations of parties on both sides of siege warfare. To explore these questions, John Spencer is joined on this episode by Laurie Blank, a clinical professor of law at Emory University School of Law, director of the International Humanitarian Law Clinic, and author of the book International Conflict and Security Law.

According to US military doctrine, legitimacy is one of the twelve principles of joint operations. But that concept—legitimacy—is a complex one. How is it defined? How should we understand the ways in which the laws of war, rules of engagement, national policies, and civilian harm mitigation measures overlap—and how they differ? How can rules of engagement and policies change in different missions, theaters, operating environments, and wars? This episode examines those questions and features an insightful discussion with an expert on the subject: Laurie Blank, a clinical professor of law at Emory University School of Law, director of the International Humanitarian Law Clinic, and author of the book International Conflict and Security Law.

In what has become a holiday tradition, the Urban Warfare Project Podcast turns its attention to an important question: What items should be on a military force's urban warfare holiday wish list? To do so, John Spencer is joined once again this year by two urban warfare scholars to discuss the unique capabilities, ideas, and initiatives they would like Santa to deliver. Major Jayson Geroux is a Canadian Army officer and urban warfare historian assigned to the Canadian Army Doctrine and Training Centre. And Mr. Stuart Lyle is the urban operations research lead for the UK-based Defence Science and Technology Laboratory. From new scholarship to cheap tactical drones, they discuss the items that would help militaries be best prepared for urban warfare.

When thousands of Hamas militants invaded southern Israel on October 7, 2023, there were only 110 police officers on duty spread across hundreds of square kilometers, concentrated in four police stations and several other posts. Despite their relatively small numbers, these officers played a critical role that day. On this episode, John Spencer is joined by Israel Police Chief Superintendent Shlomi Chetrit, head of the Israel Police History and Heritage Branch, who discusses the role of the police on October 7, including their actions during the battle for the Sderot Police Station.

Cities' complex man-made terrain, the presence of civilian populations and infrastructure to support those populations, a complicated information environment, and a range of political and other factors make planning for brigade and division urban operations extremely difficult. Too often, militaries rely on a limited set of options—such as the deliberate assault or an effort to bypass cities completely. But history yields lessons on how to overcome the unique challenges of urban warfare. Chief among these lessons is that developing operational approaches to major urban areas requires planners to account for unique, environment-specific considerations. In this episode, Dr. Jacob Stoil—the chair of applied history at the Modern War Institute, an associate professor of military history at the US Army School of Advanced Military Studies, and a senior fellow at the 40th Infantry Division Urban Warfare Center—explores these considerations and details several operational approaches for brigades or divisions in the offense, drawing on historical case studies to illustrate their value.

From ancient Jerusalem to today's urban battlefields in Ukraine and Gaza, we can find many examples of urban conflicts that have been heavily influenced by their underground components. But how should military forces categorize subterranean spaces and consider the different functions of underground structures? How does this subterranean dimension influence the conduct of military operations? What about the unique hazards of sending soldiers underground? And what are some of the planning considerations for attacking or defending subterranean positions? This episode addresses those questions and more in a comprehensive overview of underground warfare.

A strongpoint is a heavily fortified battle position tied to a natural or reinforcing obstacle. It is used to create an anchor for the defense or to deny the enemy decisive or key terrain. Throughout the history of urban warfare, buildings turned into strongpoints have played an outsized role. Multiweek battles have even been fought over single buildings used by the defender as strongpoints. In this episode, John Spencer is joined by Major Jayson Geroux, an urban warfare historian assigned to the Canadian Army Doctrine and Training Centre, and Mr. Stuart Lyle, the urban operations research lead for the UK-based Defence Science and Technology Laboratory, to discuss strongpoints on the urban battlefield.

What do engineers bring to urban operations? How do the basic capabilities resident in engineer units—like those in the US Army—enable maneuver forces to achieve their objectives when operating in cities? For commanders, what are the most important considerations to account for when employing engineers in combined arms operations, and what effects can they expect from specific engineer tactics and equipment? This episode examines those questions and more as John Spencer is joined by Lieutenant Colonel John Chambers, an engineer commander in the 1st Infantry Division.

John Spencer is joined on this episode by retired General David Petraeus. He served thirty-seven years in the US Army, culminating his career with six consecutive commands as a general officer, including five in combat. He served as the commander of coalition forces in Iraq during the troop surge there, commander of US Central Command, and commander of coalition forces in Afghanistan. Following his retirement from the Army, he served as director of the Central Intelligence Agency. He earned a PhD from Princeton University and is the coauthor of the recent book Conflict: The Evolution of Warfare from 1945 to Ukraine. He brings both scholarship and deep, firsthand experience fighting enemy forces in urban ares to this conversation.

In this episode, guest host Jayson Geroux is joined by retired Lieutenant Colonel Louis DiMarco, a professor of military history at the United States Army Command and General Staff College. Dr. DiMarco is the author of the influential 2012 book Concrete Hell: Urban Warfare from Stalingrad to Iraq. In the conversation, he discusses how he became interested in urban warfare and describes the urban warfare history course he developed and continues to teach at the Command and General Staff College. He also highlights a number of historical urban battles while also noting the themes that have consistently featured throughout urban operations history.

Many will be familiar with the major facts about the October 7 Hamas terrorist attacks against Israel. Over 1,200 people were killed and another 240 kidnapped and brought to Gaza as hostages. But what do we know about the specific sites—more than twenty in total—that the attackers selected as targets? What about the specific tactics they employed? And since many of the sites targeted were in built-up, inhabited areas, what lessons on urban warfare can be extracted from the attacks? John Spencer explores those questions and more, based on firsthand research, in this episode.
