NATO has announced a new defensive initiative, “Eastern Sentry,” aimed at strengthening the alliance’s ability to respond to Russian drone incursions. NATO Secretary General Mark Rutte and Supreme Allied Commander Europe (SACEUR) General Alexus G. Grynkewich made the announcement at a joint press conference on 12 September 2025.
This comes just two days after a wave of Russian drones entered Polish territory, sparking alarm among NATO members.
The operation is a direct response to Poland invoking Article 4 of the NATO treaty, which calls for consultations among allies when a member’s territorial integrity, political independence, or security is threatened.
Rutte said Eastern Sentry will bolster the eastern flank, ensuring the safety and security of alliance nations.
The operation will begin in the coming days and involve military assets from Denmark, France, Germany, the United Kingdom, and other member states.
NATO Secretary General Mark Rutte said the effort will combine traditional military capabilities with measures specifically designed to address drone threats.
“Eastern Sentry will add flexibility and strength to our posture, and make clear that, as a defensive alliance, we are always ready to defend,” he said.
SACEUR highlighted that integrated air- and ground-based defenses will be central to the initiative. While the immediate focus is on Poland, he emphasized that the threat transcends national borders and affects the entire alliance.
Eastern Sentry will enhance deterrence, increase information sharing, and allow rapid deployment of counter-drone technologies.
