PLA Urban Assault Drill Highlights Taiwan's Push for Stronger City Defenses

Rubble, roadblocks and a $40 billion defense plan

China's People's Liberation Army has released rare footage of troops conducting a live fire assault through a ruined cityscape, showing reconnaissance, room clearing and the seizure of a building described as critical to the city's infrastructure. The broadcast came shortly after Taiwan's president, Lai Ching-te, advanced a plan to spend roughly US$40 billion over eight years starting in 2026 on stronger defenses, particularly air defense, uncrewed systems and other asymmetric weapons.

As of December 7, 2025, the parallel developments put urban warfare near the center of the Taiwan Strait standoff. Beijing is displaying preparations for fighting beyond the shoreline. Taipei is building a more mobile, dispersed force intended to survive an opening strike, resist a landing and make any advance into its cities slow and costly.

The Chinese footage showed infantry moving through concrete rubble in light protected tactical vehicles. A heavy machine gun fired overhead while a sensor mast mounted on a vehicle roof scanned for threats. Soldiers advanced behind smoke, crossed burning barricades and rolls of barbed wire, and gathered at doorways carrying rifles and portable antitank rockets.

The broadcast gave no time or location for the exercise and did not identify the unit. Its visible sequence was a coordinated effort to enter, clear and hold urban ground. Such coordination, often called combined arms warfare, brings different weapons and military roles together so that troops can support one another.

Taiwan's geography gives those preparations particular weight. Towns and industrial areas crowd the western coast, forming an irregular urban network from Taoyuan to Tainan. A force advancing inland would face neighborhoods, roads and built infrastructure rather than an uninterrupted stretch of open ground.

What the PLA practiced inside the mock city

The PLA broadcast placed reconnaissance before movement, followed by a deliberate breach, room clearing and a phase devoted to holding the objective. In a city, each stage creates a different problem: finding concealed defenders, getting through obstacles, checking enclosed spaces and keeping captured ground supplied and secure.

The target building was described as essential to the city's functioning. Substations, telecommunications hubs, water facilities, bridges and major intersections belong to the same broad category of infrastructure that can shape an urban battle. Capturing a block provides limited advantage if a counterattack can isolate the assault force or sever its routes.

Similar PLA formations regularly train with light armored transports carrying stabilized guns and turrets combining optical and thermal sights. Thermal equipment helps soldiers detect heat, including in conditions where ordinary vision is restricted. Troops leaving the vehicles carry weapons against armor to respond to ambushes.

The rubble, flames and wire obstacles resembled the conditions used at Chinese training complexes to put assault teams under simulated combat stress. The exercise concentrated on the practical sequence of approaching a defended site, breaking in and maintaining control while other threats remain nearby.

Drones, robots and replicas of Taipei

PLA urban units are bringing uncrewed equipment into this training. Small drones scout stairwells and rooftops, while ground vehicles without crews move ammunition or investigate possible booby traps. Computer simulations let troops rehearse entry routes and fields of fire before repeating similar movements in physical mock towns.

At the Zhurihe Training Base in Inner Mongolia, replicas of Taiwanese government buildings give these preparations a more specific political meaning. Satellite imagery over recent years has shown the complex expanding. Soldiers have practiced removing barricades, establishing or negotiating roadblocks, and advancing with armored vehicles through settings resembling parts of Taipei.

The mock government buildings and a replica political district serve both training and signaling purposes. Assault teams gain places to repeat difficult tasks. Their visibility also puts psychological pressure on Taiwan by showing that Chinese forces are preparing for government districts, transport nodes and city centers as well as beaches.

Drones and robots bring their own weaknesses. Small quadcopters are noisy and vulnerable, ground robots can fail in rubble, and a computer rehearsal cannot reproduce every surprise of combat. Their growing use nevertheless reflects an effort to reduce infantry exposure and shorten the time between finding a target, identifying its position and attacking it.

Why Taiwan's cities shape its defense

Taiwan's urban areas can restrict the advantages of a larger attacking force. Tanks have less room to move, buildings interrupt the view of sensors operating over long distances, and communications can become unreliable indoors. Civilians add another layer of difficulty to every military decision.

Urban battles such as those in Mosul and Marawi illustrate how slowly fighting can progress and how quickly ammunition can be consumed. For Taiwan, imposing a prolonged struggle through streets and buildings would increase the time and resources an invader needs, while creating repeated opportunities for ambush and deception.

Taipei's first aim is to prevent a large landing. If troops reach shore, its preparations seek to turn city blocks into defensive strongpoints while disrupting the supplies needed to sustain the attack. Engineers are improving barriers, mobile units can place obstacles within hours, and precision guided weapons can threaten support ships and ferry routes.

Asymmetric defense means using tools and tactics that exploit an opponent's weaknesses instead of matching every large platform with an equivalent one. Mobile missiles, small uncrewed systems and dispersed units fit that approach because they can create problems for a heavier force without requiring equally large ships or vehicles.

Urban defense also demands restraint and organization. Troops must control when they fire, use covered routes and place obstacles or traps that direct attackers into areas where defenders can concentrate fire. Small drones, thermal sights and commercial cameras help watch alleys and rooftops, including through the night.

Supplies remain essential on both sides. Soldiers isolated inside a city can rapidly consume ammunition and medical stocks, become exhausted and suffer rising casualties. Taiwan is therefore preparing protected movement through tunnels and underground stations as well as positions from which its troops could fight.

The supply chain behind a landing

U.S. military analyses of a Taiwan conflict argue that urban defense works best when it is paired with attacks on the resources feeding an invasion. Troops crossing the strait would depend on a continuing flow of fuel, ammunition, equipment and reinforcements.

Civilian ferries, cargo ships designed to load and unload vehicles, fuel barges and small landing craft could become part of that supply network. Missiles based on shore, artillery rockets and fast attack boats could threaten those vessels and the routes they use.

Interrupting the flow would force an attacker to pause or continue deeper into cities with shrinking stocks. Defenders would seek to combine that pressure with the heavy consumption of supplies inside urban areas. The intended result is a contest in which maintaining the advance becomes progressively harder.

Han Kuang brings the fight into the capital

Taiwan's largest annual military exercise, Han Kuang, has been redirected toward a conflict that could spread from beaches into urban centers. Its most recent iteration lasted ten days and nine nights, twice the usual duration, and tested command decisions under conditions that were less scripted.

More reservists were called up than in previous years. Civil agencies joined the exercise to practice keeping electricity, transport and emergency services functioning during wartime disruption. The longer schedule put sustained operations, rather than a brief demonstration, at the center of the test.

At the Wanban Bridge between New Taipei and Taipei, military police closed the crossing during the early morning and built a blockade with four layers. Buses, concrete blocks, wire coils and rapidly assembled Hesco style protective bastions created successive barriers intended to delay an approaching force.

Drones watched a simulated approach, snipers operated from elevated positions, and domestically produced Clouded Leopard wheeled vehicles swept the bridge to clear simulated infiltrators. The drill addressed a practical defense task: restricting access to bridges and intersections leading toward the Presidential Office Building and transport hubs.

The bridge exercise also showed how military plans depend on ordinary city infrastructure. A crossing used for daily travel can become an approach route, a defensive position or a bottleneck. Coordinating its closure requires military units and civilian authorities to work within the same plan.

The Metro becomes a route for troops and supplies

Taiwan has also used the Taipei Metro to rehearse moving troops and supplies while the system was closed to passengers. Soldiers practiced boarding with heavy weapons, loading materiel onto maintenance cars and emerging at stations near potential conflict areas before moving underground again.

Metro tunnels offer protection from missiles and aircraft and could provide space for temporary command posts or field hospitals. Their military use also creates difficult choices because the same network serves civilians. Transport safety and the coordination of military activity with civilian needs remain part of the preparation.

For defenders, the attraction is movement under cover. Roads exposed to observation and attack can become difficult supply routes. Underground connections could help units relocate and receive equipment while reducing the time they spend above ground.

Civil defense and Lai's argument for deterrence

Taiwan's civil defense exercises, presented as urban resilience training, have been combined with Han Kuang. Sirens sound across northern cities, vehicles pull over, shops close and residents move to shelters while mobile alerts give instructions.

The procedures include entry only arrangements at Metro stations and blackouts when ordered. Authorities have also signaled that people who disregard instructions can face fines. The aim is to make public behavior more predictable during disruption and keep emergency measures working when large numbers of people need help.

Lai has visited reservist training and observed instruction in small drones and urban blocking tactics. He has tied military reform and public preparedness to deterrence, the effort to prevent an attack by convincing a potential aggressor that its costs would be too high.

During one inspection, President Lai Ching-te described military strength as the basis for the peace Taiwan seeks:

Taiwan must rely on strength to obtain true peace.

His proposed spending plan would fund air defense upgrades and accelerate the development of uncrewed aircraft and maritime systems. Those systems could observe, attack or deliver supplies at a fraction of the cost of larger platforms. The approach reflects lessons from recent conflicts in which relatively cheap, mobile equipment has complicated operations by heavier forces.

The roughly US$40 billion allocation over eight years beginning in 2026 still depended on approval by lawmakers. Its practical purpose would be to help Taiwan survive initial attacks, maintain surveillance and keep dispersed forces operating.

Military messages and equipment schedules

Beijing's urban assault broadcast combined training with strategic communication. Chinese leaders have called for more realistic combat preparation, and televised scenes of troops fighting through mock towns display progress toward that demand while applying pressure to Taiwan.

Taiwan's longer exercises, reduced scripting and participation by civilian agencies send messages to both partners and adversaries. Foreign observers, including retired officers and defense industry representatives, have attended training sites, reflecting outside interest in how the island prepares.

Those exercises also expose problems for the authorities to address. Transport safety, clear chains of command and coordination between central and local governments are being refined through successive rounds of training.

Equipment schedules form another part of the competition. China's third aircraft carrier, Fujian, is moving through trials. PLA aircraft and drones regularly cross the Taiwan Strait's median line, while Chinese air and naval activity near Taiwan has become routine. Taiwan's mobile rocket artillery and additional air defense systems are arriving on staggered schedules.

The main sequence described by the preparations is:

• In recent years, satellite imagery has shown expansion at Zhurihe, where PLA troops train around replicas of Taiwanese government sites.
• The most recent Han Kuang exercise ran for ten days and nine nights, combining military operations with civilian resilience measures.
• Lai advanced an eight year defense spending plan beginning in 2026, followed shortly afterward by the PLA urban assault broadcast.
• As of December 7, 2025, Taiwan's proposed allocation required legislative approval, Fujian was undergoing trials and Taiwanese equipment deliveries were proceeding in stages.

How planners connect blockade, landing and city fighting

A possible conflict could begin before troops approached a city. China could seek to isolate Taiwan through a blockade, cutting air and sea traffic and restricting supplies of food and fuel. Precision strikes could then target air bases, radar installations and missile batteries.

Small, mobile teams could also attempt raids on bridges or government offices. Taiwanese planners anticipate possible efforts to land near airports or ports and quickly open a route toward the political center. Exercises at Taoyuan Airport and urban bridge crossings reflect those concerns.

If PLA troops secured a foothold, attackers would seek routes along wide roads and rail lines, elevated positions on overpasses or office towers, and utility sites that control power and water. Defenders would try to break those routes with obstacles and attack the forces supplying the advance.

Possible defensive measures include collapsing stairwells, flooding tunnels if needed, and using missiles and rockets over short distances against support columns and logistics hubs. Small teams could strike armored units with antitank weapons before withdrawing through side streets or Metro access points.

Taiwan's partners could focus on the transport network sustaining an amphibious attack. Intelligence gathering and strikes against ferries, barges and supply vessels in embarkation ports could slow deliveries across the strait. Submarines and aircraft could complicate resupply without seeking full control of the sea.

The central connection is between distance and consumption. An attacking force must bring supplies across water, move them inland and distribute them through contested streets. Taiwan's preparations aim to place pressure on each part of that journey while prolonging the fight in built areas.

Drones, communications and the risk of escalation

Drones would have roles throughout such a battle. Small quadcopters can drop small munitions, locate snipers and follow vehicles through alleys. Larger uncrewed aircraft can watch convoys and send targeting information to artillery units.

Both sides are fielding jammers and decoys to interfere with those activities. Jammers disrupt the signals used for control or communication; decoys try to draw attention toward a false target. Keeping a reliable communications network while disrupting the opposing network would be a major advantage in dense urban terrain.

Information reaching civilians would matter too. Rumors, panic and disinformation can travel quickly through crowded districts. Taiwan's standardized alerts and civil exercises aim to maintain order when electricity or communications fail.

China would seek to spread confusion through cyberattacks and manipulation on social media. Taiwan would seek to distribute verified information through radio, text messages and public address systems. Reliable instructions could affect whether residents reach shelter and whether roads remain usable for emergency services.

Military exercises train personnel, demonstrate resolve and try to influence decisions. Real combat introduces uncertainty, disrupted plans and events that can move faster than commanders expect. More frequent and realistic activity around Taiwan also creates opportunities for accidents or misunderstood signals to escalate.

Beijing and Taipei are both seeking capabilities they believe will deter the other while avoiding an incident that spirals out of control. For Taiwan, preparation means keeping civilians informed, maintaining supplies under attack and threatening an invading force's transport links. For the PLA, it means practicing operations against small, mobile defenders in streets those defenders know.

The prospect of a city battle would carry devastating costs for soldiers and civilians. The footage of ruined streets, the barriers across a Taipei bridge and the movement of troops through Metro stations show why both militaries are preparing for a conflict that could extend far beyond a beach landing.
