The Underground Strategy: Germany’s Berlin Exercises Inspired by Taiwan
Last July, the Taiwan subway experience took an unexpected turn. Instead of the usual passengers bustling with their belongings, troops armed with anti-tank missiles filled the stations. This operation aimed to send a dual message: one of resolve within the nation and another directed towards China.
Germany’s Bold Emulation of Taiwan
Inspired by Taiwan’s unique approach, Germany has embarked on its rearmament journey. Recently, in Berlin, the German army executed the Bollwerk Bärlin III exercise, bringing soldiers back into an urban battleground reminiscent of the past century. Soldiers could be seen descending U-Bahn stairs into simulated chaos, complete with smoke, mock gunfire, and vehicles overtaken by “saboteurs.”
Transforming the U-Bahn into a Tactical Training Ground
Over three nights, approximately 250 members of the Wachbataillon—traditionally known for ceremonial duties—transformed subway stations like Jungfernheide into authentic underground battlefields. This exercise focused on critical skills: assault tactics, civilian evacuation, and essential infrastructure protection within the real confines of the subway system, emphasizing real-world conditions such as limited visibility and confined spaces.
A Renewed Sense of Urgency Against Russian Threats
The shift towards urban warfare is reflective of deep-seated concerns regarding potential conflicts, particularly with Russia. Analysts noted that operations like these symbolize Germany’s evolving strategic landscape. Gone are the straightforward military preparations of the past; today’s exercises must equip forces to respond to threats that feel increasingly imminent.
A Historical Shift: From Ceremonial to Combat Ready
The Wachbataillon’s transformation underscores a significant metamorphosis. Once merely a display of national stability, the battalion’s role has evolved into a crucial defensive force, tasked with protecting the government and its infrastructure in crisis situations. Colonel Maik Teichgräber emphasizes the need for readiness for “the worst-case scenario,” which involves real combat training in urban settings.
The Modern Battlefield: Underground Operations
Utilizing stations closed off to the public allowed the Bundeswehr to practice quick assaults on trains, enemy neutralization, and rapid medical evacuations within the confining spaces of the city. Additional scenarios, like the former Rüdersdorf chemical plant, show a desire to create a multifaceted defense strategy that can handle everything from internal sabotage to major incursions targeting Germany’s political heart.
Global Resonance of Urban Warfare
Germany’s method of utilizing urban infrastructure is mirrored in other global contexts. Taiwan’s subway system serves as a vital asset during military exercises, while the U.S. places a priority on underground warfare preparation for its special forces. This shift comes as urban landscapes become increasingly fortified, and the proliferation of drone warfare becomes a prevalent concern.
A New Dimension in Warfare
As unmanned systems gain prominence, future warfare will require defending both above and below ground. Command of subways, tunnels, and interconnected bunkers will be of strategic importance, necessitating a dual focus on aerial and subterranean threats.
Echoes of the Cold War
This training brings to mind a divided Berlin, where urban operations were rehearsed to delay invasions. With the rise of present-day uncertainties, Germany is revisiting these strategies, recognizing the necessity of a robust civil defense structure previously thought obsolete.
Historical Rearmament
Germany’s military enhancement plans are set to increase defense spending drastically by 2029, reflecting a significant shift from pre-COVID budgets. This transformation not only modernizes capabilities but also adapts the military to contemporary threats, particularly those emanating from 900 kilometers away in Ukraine.
The Path Ahead for European Security
Teichgräber’s remarks highlight the reality that the war engulfing Ukraine could one day reach German soil. The future isn’t just about defending borders; it’s about safeguarding Europe from emerging hybrid threats within its cities. The Underground in Berlin now serves as a potent reminder of preparedness in a world where the security of Europe can no longer be taken for granted.
Conclusion
What we witness in Berlin is not merely a rehearsal but a reflection of the new realities of warfare. It illustrates a pressing need for adaptability in strategy, indicating that the fate of cities like Berlin may well hinge on the actions taken underground.
