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....

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...

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...

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...

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...

He served 30 years in the US Army, with his last assignment as chief of Army Capabilities and Integration Center's Future Warfare Division. He describes the Army’s different approaches for thinking about and studying the future of warfare, including major efforts beginning in 2014 to focus on global urbanization, including by incorporating it into wargames like Unified Quest. The discussion highlights the complex...

During the 2022 Battle of Mariupol, approximately three thousand Ukrainian defenders, vastly outnumbered by Russian forces, were quickly surrounded in a steel plant with their backs to the Sea of Azov and little hope of anyone coming to their rescue. Running out of ammunition, short of medicine, and with casualties mounting, they were in desperate need of resupply. A bold plan was conceived, which would involve risky helicopter flights to the besieged defenders. In this episode, John Spencer...

Over several dozen episodes, the Urban Warfare Project Podcast has explored many of the unique challenges of urban warfare. But what is urban warfare, exactly? The simple answer is that it's simply combat that takes place in the man-made terrain of cities. But going deeper, what are the variety of urban patterns and urban functions, for example, and how do they influence the conduct of military operations? What about building types and construction materials? And how do all of these variables...

When Russian forces invaded Ukraine in February, one of their first targets was the city of Mariupol. The battle that followed is an epic story of resistance in which a very small number of Ukrainian fighters defended the city for over eighty days against a Russian force five to eight times their size, preventing the Russians from diverting to other parts of Ukraine. In this episode, John Spencer is joined by Aiden Aslin, a British citizen who took part in that battle and was captured by...

The laws of war govern the initiation and conduct of armed conflict. What can be legitimately targeted? What constitutes a war crime? The laws of war provide answers to these questions and others. They apply everywhere, but there are unique considerations in certain environments—especially in cities. The hostilities in Gaza over the past several weeks offer a case in point. To examine the laws of war and their application in urban areas, and to specifically explore the case of Gaza, John...

In this episode, John Spencer is joined by Dr. Deane Baker, an associate professor at the University of New South Wales, Canberra at the Australian Defence Force Academy. He specializes in the ethics of armed conflict, and he joins the podcast to discuss his research on military ethics and how ethical dilemmas present themselves on the battlefield. In particular, he explains why urban warfare creates a context that generates unique ethical concerns—concerns that remain unresolved and are of...

Almost immediately after Hamas launched its brutal set of terrorist attacks in Israel, it became clear that the Israel Defense Forces would respond militarily. That meant a campaign against Hamas targets in Gaza. Because of Gaza's heavily urban terrain and the specific location of Hamas military forces, the fight has occurred—and will continue to occur—in deeply challenging environments for military forces, places where the law of armed conflict's provisions aimed at protecting civilians must...

If the Israel Defense Forces conduct a ground campaign in Gaza, the threat of Hamas tunnels will be one of the most significant challenges to contend with. But how many of these tunnels are there? What can Israeli forces do about the tunnels when they encounter them? Can they seal them? Can they destroy them with bunker-buster munitions or other explosives? The answers to these questions are not simple. In this episode, John Spencer welcomes Dr. Daphne Richemond-Barak back to the show. She is...

On October 7, when the militant group Hamas launched a large-scale set of coordinated attacks against Israel, the tragic result was the deadliest day in the country's history.

On February 24, 2022, when Russian forces invaded Ukraine, they quickly targeted several key cities. One of those was the industrial hub of Mariupol. For three months, Ukrainian forces defending the city held out, until they were told to surrender on May 20. While thousands were taken into captivity, many whom are still being held as prisoners of wars, at least one civilian fighter, a man named Gennadiy, survived and remained in the city. In this episode of MWI’s Urban Warfare Project...

How does Ukraine’s military balance the need to train its forces and fight in a major land war at the same time? In short, any way it can. That includes training led by a number of organizations created and staffed by foreigners in Ukraine, among whom are a number of military veterans from the United States. In this episode, John Spencer speaks to one of those them. Retired US Army Lieutenant Colonel Erik Kramer is the cofounder and director of the Ukraine Defense Support Group. He describes...

He also explains the historical trends that influenced the form Phalanx would take and details the specific changes made to...

Since Russia's invasion of Ukraine last year, a series of battles have taken place for control of cities—Kherson, Mariupol, Kharkiv, and many more. Each of those fights have shared a common characteristic—the presence of civilians—that also represents one of the greatest challenges in urban warfare. Specifically, how can a military force protect noncombatants while it seeks to accomplish its objectives in a city? To explore this question, John Spencer is joined on this episode by Sahr...

When Russia invaded Ukraine in February 2022, one of its first targets was the city of Mariupol. Despite being outnumbered by—and less well equipped than—their adversaries, Ukrainian defenders held out for three months. As the Russian siege of the city intensified, Ukrainian forces defended a shrinking perimeter with a command post in the Azovstal steel plant. One of those Ukrainian defenders was Sergeant Arseniy Fedosiuk. He joins John Spencer on this episode, relaying his experience in...
