NATO stages largest eastern flank drills as Germany, France test AI and high-intensity combat

Lithuania hosts NATO’s largest-ever eastern flank exercise as Germany’s new Panzerbrigade 42 trains for high-intensity combat, with France deploying AI-powered battlefield command systems in a parallel drill.

For the first time, the Bundeswehr’s Panzerbrigade 42 “Lithuania” conducted live-fire manoeuvres near Rukla on Sunday, simulating the high-stakes conditions of a full-scale conflict along NATO’s eastern frontier. “In a real war, I would already be dead,” said a German Leopard 2 tank commander, underscoring the brigade’s role as both a deterrent and a proving ground for the alliance’s war-fighting readiness.

The drills, held under NATO’s enhanced Forward Presence framework, mark the alliance’s most ambitious eastern deployment since Russia’s 2022 invasion of Ukraine. More than 4,000 German troops, supported by Dutch and Norwegian detachments, are testing integrated air-defence, electronic warfare, and long-range strike capabilities in a contested environment. The exercise follows last week’s activation of the brigade’s forward command post in Lithuania’s Pabrade training area, where commanders are rehearsing rapid reinforcement under simulated cyber and missile threats.

France, meanwhile, is integrating its own AI-driven command-and-control system into NATO’s annual “Steadfast Defender” exercise, which concludes this week. The system, developed by the Direction Générale de l’Armement, uses machine-learning algorithms to process real-time sensor data and recommend tactical decisions to brigade-level commanders. “This is not about replacing human judgement, but accelerating it,” said a French defence official. The AI module will be stress-tested against electronic warfare jamming and spoofing scenarios during the final phase of the drills.

The twin exercises reflect NATO’s pivot from theoretical deterrence to operational war-fighting, with eastern members pressing for permanent brigade-sized units rather than rotational battlegroups. Lithuania’s defence minister, Arvydas Anušauskas, told reporters that the drills send a “clear signal” to Moscow while accelerating Lithuania’s integration into NATO’s integrated air and missile defence architecture.

Analysts note that the German brigade’s deployment—just 18 months after its formation—signals Berlin’s accelerated reorientation toward high-intensity land warfare, a shift confirmed by the Bundestag’s May 2026 approval of €12 billion in emergency procurement for Leopard 2 upgrades and Patriot missile batteries. The exercises also coincide with NATO’s push to secure critical supply routes for rare-earth minerals, as highlighted in a separate report on Europe’s AI-driven strategy to secure African mining assets.

With tensions in the Baltic Sea region remaining elevated, NATO officials insist the drills are defensive in nature. Yet the presence of live ammunition, electronic attack pods, and AI-assisted targeting systems underscores the alliance’s readiness to escalate rapidly if deterrence fails.
