Last July, the Taiwan subway experienced an unusual day: Instead of passengers loaded with purses and suitcases, soldiers, soldiers and more soldiers armed with anti-tank missiles began to arrive at Taipei stations. The reason was twofold: to send a message inside and outside (China) of the country.
That idea seduced Germany, and now that it has begun its rearmament it has launched in Berlin.
A disturbing return. The exercise Bollwerk Bärlin III Last week, he returned to the German capital a scene that seemed banished to the memories of the 20th century: soldiers descending U-Bahn stairsjumping onto the tracks and advancing through smoke, simulated gunshots and cars taken over by “saboteurs.”
For three nights, between 1 and 4 in the morning, about 250 members of the Wachbataillon (a unit known for its ceremonial role but with infantry functions) transformed stations like Jungfernheide into a real underground battlefield to practice assaults, close combat, evacuation of civilians and protection of critical infrastructure in a realistic environment in which nothing is altered or mocked up: the narrowness of the tunnels, limited visibility and changes in light are the same as they would find in a real war scenario.
In the background: Russia. They remembered the TWZ analysts that this return to urban warfare in tunnels and stations, without embellishments or theatrical simulations, symbolizes a profound change in Germany’s strategic priorities and revealed the extent to which the shadow of a possible conflict with Russia has penetrated into the very heart of Germany. his military planning.
The metamorphosis. The battalion in charge of displaying honors on state visits had been conceived for decades as a symbol of institutional stability, not as a combat force. However, its real operational mission (protecting the federal government and its facilities in the event of a crisis) today takes on an urgency that has not been seen for a long time. Hence the direct tone of his commanderlieutenant colonel Maik Teichgräber: Berlin is your area of operations and they must prepare for “the worst case scenario,” which means training where you would really fight.
The use of stations closed to the public allows practice quick entriesassaults on trains, neutralization of enemies and immediate removal of wounded, integrating snipers, perimeter security and coordination between units in a densely urbanized environment. The presence of additional scenarios (such as the former Rüdersdorf chemical plant or the Ruhleben police complex) underlines the desire to turn the capital’s defense into a multidimensional exercisecapable of absorbing everything from internal sabotage to coordinated incursions that seek to paralyze the political center of Germany.
Global dimension of the trend. Which happens in Berlin It is also reflected in other regions of the world. How we countTaiwan uses its subway as a defensive artery during the Han Kuang exercises, aware that, in the event of a Chinese invasion, underground infrastructure they would be vital to move troops and supplies while the surface becomes a continuous target. In parallel, the United States has raised the underground war a priority for its special forces, responding to the proliferation of fortified tunnels, dense urban areas and the expansion of drone swarms that force troops to seek refuge underground.
The growing autonomy of unmanned systems, already present in Ukraine, accelerates this trend: in a future where aerial surveillance will be almost constant, defending in depth will mean dominating not only streets and buildings, but subways, tunnels, pipelines and interconnected bunkers. The war of the future, according to these emerging doctrines, will be fought both upwards (against drones, sensors and loitering munitions) and downwards, in an underground network that takes on strategic value.
Echoes of the Cold War. He training on the U-Bahn inevitably refers to a divided Berlinwhen the city was a western enclave surrounded by Warsaw Pact forces. At that time, the United States, the United Kingdom and France were rehearsing urban operations aimed at slowing down an invasion to gain political time, aware that holding the city indefinitely was unrealistic.
Units like the (secret) Detachment A They practiced sabotage and unconventional warfare techniques from the shadows. Even stations, such as Pankstraße or Siemensdamm, were designed like nuclear shelters for more than 3,000 people for weeks, with armored doors and air filtering. The reunified Germany had left behind that architecture of fear, and today, faced with a panorama of uncertainty, it returns to study how to reactivate these civil protection capabilities. The contrast is evident: what in 1994 seemed unnecessary is once again considered a strategic necessity.
Historical rearmament. we have been counting. The exercise is also part of a context transformation unprecedented german military apparatus. By 2029, Berlin plans spend 153,000 million euros per year in defense (around 3.5% of GDP), an enormous jump from the levels that for decades were a source of friction with Washington.
It is a rearmament designed not only for modernize capabilitiesbut to adapt the country to threats that They are no longer theoretical: What happens 900 kilometers away, in Ukraine, conditions the entire strategy. This budget increase has led NATO to consider a symbolic turn that would have been unthinkable during the Cold War: that Germany would command the allied forces in Europe. Although that moment has not arrivedthe expectation underscores the pressure on Berlin to demonstrate that it can take on top responsibilities and is willing to prepare its military for complex scenariosfrom urban sabotage to large-scale conventional warfare.
Strategic warning. Teichgräber put it clearly: Nobody can guarantee that the war that is currently devastating Ukraine will not one day reach German territory. That phrase sums up the background of Bollwerk Bärlin III. The Bundeswehr trains in the subway tunnels because it understands that contemporary conflicts do not respect borders or capitals. The hybrid warcoordinated attacks on critical infrastructure and the massive use of drones They make the interior of cities as vulnerable as their borders.
If you like, what is at stake is not only the defense of Berlin, but Germany’s capacity to react facing a moment in which the strategic certainties of the postwar have been blown up. For the first time in decades, the capital’s underground is once again a stage military preparationa reminder that European peace should no longer be taken for granted and that the future of continental security is also being written underground.
