# NATO Baltic security and defense strategy > Live situation record from CLSTR: https://clstr.news/situations/nato-baltic-security-and-defense-strategy > Updated: 2026-10-03T03:05:01.000Z. Sources: 16. Developments: 5. NATO officials report significant improvements in the military security of the Baltic states, driven by the implementation of the Deterrence and Defence of the Euro-Atlantic Area (DDA) strategy. This approach integrates regional defense with national-level planning to address evolving threats and capability gaps. Specific operational successes include the ‘Baltic Sentry’ operation, which has reportedly prevented further incidents of underwater cable cutting, and the ‘Eastern Sentry’ operation, designed to protect the alliance’s eastern flank airspace. To further bolster regional security, NATO is prioritizing investments in emerging technologies, such as artificial intelligence, autonomous systems, advanced air defense, and cybersecurity. Efforts are focused on ensuring these high-tech systems are fully integrated into NATO’s command, communication, and intelligence networks to provide real-time data sharing. In a significant structural shift implemented in August, NATO transitioned its Baltic Air Policing mission into a broader air defense mission. This expanded mandate moves beyond monitoring Russian military aircraft to addressing a wider range of threats, including missile risks and unmanned aerial vehicles (UAVs). The new model aims to improve coordination between Lithuanian and NATO command centers. As regional tensions persist, Lithuania, Latvia, and Estonia are intensifying military preparations to counter potential Russian aggression, specifically planning for scenarios where United States assistance might be delayed or limited. In Lithuania, large-scale simulations involve the Lithuanian Riflemen's Union—a volunteer organization that has doubled in size since the 2022 invasion of Ukraine—training civilians in combat roles and intelligence gathering. Defensive measures include constructing anti-tank trenches and ‘dragon’s teeth’ concrete barriers along the Belarusian border. Officials emphasize that the first 72 hours of a conflict would be decisive. Recent intelligence reports indicate that while there are no immediate signs of a large-scale conventional invasion, there are heightened warnings regarding hybrid warfare. ## Claims - Any Russian incursion into Lithuanian territory will be met with a counterstrike.
