After three years at the helm of the International Military Staff (IMS), Lieutenant General Janusz Adamczak (POL Army) concluded his tenure as Director General. Appointed in July 2022, General Adamczak led the IMS through a period of raising challenges, leading to strategic adaptation, increasing of NATO's deterrence and defence posture, and enhanced coordination across the Alliance's military structures.
At a farewell ceremony held at NATO Headquarters, Admiral Giuseppe Cavo Dragone, Chair of the NATO Military Committee, praised Lieutenant General Adamczak's tenure, stating: "Your leadership has not only shaped the IMS, but has strengthened the very core of our Alliance. The IMS has been able to support the Military Committee and me, every single day, ensuring that we could focus on our purpose: to build and maintain the greatest military Alliance the world has ever known."
In a farewell address to the IMS, Lieutenant General Adamczak praised his staff: "Trust between divisions, between military and civilian personnel, and between nations, has been the foundation of everything we've achieved. Our responsibility has been to provide honest, professional, and clear military advice, even when it is difficult. And that is precisely what this staff has done. You have delivered truth without hesitation, and you have done so with integrity. Thank you to every single one of you who contributed - often quietly, often without recognition - to the mission we serve. Your work has not gone unnoticed. Your dedication has not been taken for granted."
During his time as Director General, the IMS continued to play a pivotal role in shaping NATO's military response to a dynamically changing security environment. From supporting the Alliance's evolving defence posture to enhancing its ability to respond to crises, and from coordinating support to Ukraine to advancing military planning coherence, the IMS helped align strategic decisions with real-world implementation.
Lieutenant General Adamczak is succeeded by Lieutenant General Remigijus Baltrėnas (Lithuania Army). A senior officer with deep experience in national and international defence roles, Lieutenant General Baltrėnas was selected for this position by the Chiefs of Defence at the 2024 Military Committee Conference in Prague. He takes up the post as NATO continues to adapt to a new era of collective defence.
The International Military Staff is the executive body of the Military Committee and NATO's primary source of military expertise at Headquarters. Comprising both military and civilian personnel from across the Alliance, the IMS provides sound expertise across the whole spectrum of military activities to the Military Committee, thus contributing to the synergy between NATO's political and military structures, and supporting the consensus-based decision-making process.
